For the asking price I thought to try them out to go along with my purchase of Thomas’s Discovery mono blocks *** Absolutely Superb *** I will never buy high priced interconnects again ,,Well Done Thomas !

I had been eyeing the TS A75 for a few months and kept it on my short list of amplifiers. When I saw these available on the site, I immediately bought them, already familiar with the rave reviews surrounding the TS A75.

They look fantastic and run impressively cool. There is plenty of power on tap, with no trouble driving my lower-efficiency speakers. They sound far bigger than their wattage would suggest, delivering a surprising amount of current and authority.

Anyone who values dynamics should be more than pleased. The presentation also offers a spacious, airy soundstage with excellent spatial cues. I usually judge new gear by one simple test: whether it gives me that feeling where I don’t want to stop listening. With these, I kept telling myself, “just one more song.”

I received my (2) P100 Power cables two days from ordering and I must say the packaging and presentation exceeded my expectations for this price point. I am currently using them with my new Galion Discovery Monoblocks which have also exceeded my expectations. I was using Wireworld's Stratus 10s, but the P100s will be staying in this system now. I look forward to your future releases

i am really impressed with the subtleness of the tube sound in the p75. i have 2 discovery amps driving my speakers. right now i have the starke bookshelf but i change to buchardt p300 and jbl 4411or def tec dm60. all have a different sound, i have bought the Lii Song ZF15 M, they are not here yet. if they sound weird with Galion i have an el 34 amp at 15 matts max on triode output

The Galion P75 is a beautifully voiced preamplifier that strikes a rare balance between transparency and musical warmth. It delivers a wide, holographic soundstage with excellent low-level detail, while preserving natural tone and dynamics. Build quality feels solid and purposeful, reflecting its high-end intent. An outstanding choice for listeners who want refinement, realism, and long-term listening pleasure.

The best audio systems have balance. They aren't too anything(either positive or negative). They give you the right amount of everything. I used to think that was obtained by just throwing more money at the problem...That is a mistake I made time after time for decades. I've shifted goalposts and changed what I am aiming for in the hobby. I'm not in search of better (specs/watts/snr etc...) and searching for more satisfaction listening to music. That is not found in a spec sheet. You have to identify what attributes in an audio system make you want to listen to "just one more song" over and over. For me, the Discovery monoblocks get it all perfectly balanced. My sytem is very linear/matter of fact speakers and these amps have given them life that takes advantage of their capabilities. This balancing act is a remarkable feat and at this price point is really a testament to Thomas' passion for the hobby. Are these the best purchase I've made in the last 25 years in the hobby-quite possibly.

Very nice power cables. Solid build quality. Packaging is also top notch.

Bought a tsa 75 amp and a p300 power cord.The improvement over the standard cord was a wake up call.This was the best upgrade since my stand alone dac.When I ordered the Discovery Monoblocks I naturally got 2 more p300 power cords.I’ll eventually replace all my standard power cords in my system.Highly recommended.

Upon taking delivery of the Discovery mono blocks including Galion’s silver RCA interconnect’s I wasn’t expecting much in the way of attention grabbing sonics certainly with little run in time put on them ,,…LOL was I wrong ,so down the road it excites me knowing there’s much more to come . The Navy preamplifier should be the icing on the cake so to speak ,,,,.WELL DONE Thomas !

Had some power issues with my electricity which I didn't know about till I switched over to a transformer based amp but I’m very happy with it. Had a emotiva xpa gen 3 amp before and this is a big upgrade compared to it. Currently running bookshelf speakers and the bass punches hard and fast, it’s kinda a weird experience. Still waiting on some new equipment but it sounds so good right now.

I bought the Galion Discovery Monoblock for my B&W center channel because I knew my center was weak, muddy and I could not hear the dialogue even at high volume so I had been looking for a good amp and I am so glad I found the Galion Discovery Monoblock. For those who into the hometheater you know how hard and how expensive to have a decent sound system for movies, I already tried three amplifiers and still not happy. My system is 11.2 channels, Denon AVR -4700, Musician Knight for front L&R speakers, B&W center and the rest are satellite Energy Take speakers. The left and right speakers are driven by the Classe CA-300 and all the satellite speakers connected directly to the Denon AVR and of course the center is connected to the Discovery. First video I watched was Khatia Buniatishvili Beethoven piano concerto no. 1 and my goodness, it sounds incredible, the music is so inviting, detailed, clear and lively. I can hear and feel the vibrations from the cellos, I was shocked of how good the Discovery is. Ladies and gentlemen, this is truyly a hi-end performance monoblock, it has a lot of bass, a lot of power and details. When setting up center speaker level, I only adjust the level to -8.0 dB to achieve 75db at reference level. For the left and right speakers driven by 300W amplifier, I have to adjust them to -2.0 dB. For movies, I rewatched many of my favorite movies like 300, the Shallows, Bad Boys for life, Kill Bill vol. 1, the Matrix, Mission Imposible, the sound of the music.....and I can't believe how good they sound. Watching the fight in Kill Bill chapter 5 Showdown at the House of Blue Leaves, I feel I am in the fight, it's so realistic. For scary movies fans you will be startled and jump off your seat because the sound, yes I can hear the pin drop. I also listened 5.1 and Atmos music for a few hours and it sounds great. I am really happy with the Discovery and I plan to buy a pair of Discovery monoblocks for my left and right speakers to replace my Classe CA-300. I highly recommended the Discovery monoblocks for those who want to upgrade your system. Thomas, I can't thank you enough for bringing this hi-end product to us, it beats many amps out there that cost 3 times the price.

Galion Discovery

Through the years I have had many amplifiers, from many brands and all costing much more than these mono blocks. All of them had much more power and watts RMS, etc. I do believe in diminishing returns when it comes to audio, and these amplifiers make a clear statement here in comparisons! Sometimes one gets what one pays for and others maybe not.

The Galion Discovery, just out of the box, to shelf, connected, powered on…….WOW!
Words that came to mind…clear, revealing, and so musical. Playing tracks I know very well now have more details, but NOT analytical at all. Chris Botti “When I fall In Love”, track 2 “What’ll I Do”. Paula Cole vocal, Vinnie Colaiuta drums. This is so much more than a delicate brush, and cymbal treatise and when Paula takes a small breath before singing….I now hear it forward of the speaker, dare I say in the room! Yamamoto, Tsuyoshi Trio “Midnight Sugar”. To me these amps redefine this track, in there Tsuyoshi hits the keys hard at times, but they now come through as they should, music, simply sublime. Nat King Cole “The Very Thought of You, a test of vocal reproduction, Discovery deliver as though present, so smooth. Johnny Hodges “I Didn’t Know About You”, this track has much for a system to handle without harshness, the Galions came through. Steely Dan “Babylon Sisters”, a fine recording for sure in SACD, now so smooth as well. I could go on, but it is clear these are special. While I continue to listen, and can’t seem to stop….the money has no relevance here, but a creators vision and voicing are self evident. Thank-you Thomas!

System: Two JL Audio Fathom F112 Subwoofers, crossover with JL Audio CR-1 90 hz to subwoofer, thus bass from satellites not a heavy load. So, I am not concerned with bass emphasis in main amplifiers, and I am in a tuned room I built. On the small tower, two amps are fine, but on power hungry large towers, Im getting another pair of Galion Discovery!!

Every review of this Giant Killer amp is SPOT-ON!!! I'll attempt to describe my experience with a bit more emotion and passion. Cause ultimately, isn't music all about plunging into those sweet vocals and instrumental arrangements with a beautiful story line? This A75 amp brings a tight, evocative analogy that captures sweet, entrancing bass,mids and highs. I'm using gas vs. diesel analogy, with diesel as the more captivating character in my story. Think of a typical power-amp a gasoline engine: quick to rev, immediate, punchy, and exciting on first hit like my 200wpc Emotiva amps or my flagship Tonewinner 300wpc amp. They jump off the line with snap and speed, delivering impact that’s fun and energetic I thought I was happy with this kinda sound— but...it can feel a little lightweight, a little breathless once the novelty wears off. Now I'll try to compare that to diesel the TS A75 amp. This truly sweet power amp delivers like a well-tuned diesel engine — not flashy, not frantic, but deeply compelling. The torque is there from the very bottom, effortless and unforced. Notes don’t just hit; they roll in with weight and inevitability, pressing into the room with a smooth, steady authority that draws you in rather than shouts for attention. This kind of sound doesn’t rev high — it pulls. It has density, texture, and a sense of momentum that feels grounded and muscular yet refined. Instead of a sharp jab, it’s a continuous surge, one that locks rhythm in place and makes the entire acoustical presentation feel more cohesive and immersive. On the other hand, gas excites you, but diesel keeps you engaged and listening. That’s the difference between musicality that impresses (my ToneWinner and my Emotiva amps) and musicality that entrances. (TS A75 amp) — the kind that makes you lean back, relax, and let the music carry you forward on a wave of effortless torque. Don't forget, I'm still talking about musicality here. The difference is speed (gas: how fast the music shoots out of the speakers vs diesel torque: how much of the musically entrances your ears and tugs at your heartstrings when it reaches your perfectly positioned listening chair where the cushions are shaped like your bottom side. This transformative Giant Killing power amp is enigmatically amazing. Gas excites you. Diesel bass keeps you listening. This difference is exactly what Thomas's current designed amps deliver IMHO— the kind that makes you lean back, relax, and let the music carry you forward on a wave of effortless torque. Yes sound stage larger yes more air and all that yada-yada-yada. But I digress. The Galion A75 has done something remarkable with my Klipsch La Scalas and my Klipshorns both Heritage series— it hasn’t just powered them, it has resurrected them. These speakers have always been capable of immediacy and scale, but with the A75 driving them, they’ve taken on a new sense of weight, flow, and emotional authority that’s downright hypnotic. The bass is no longer just fast and punchy — it’s sweet, torquey, and grounded, filling the room with a diesel-like pull that anchors the music and gives every note a sense of inevitability. They don’t shout any more (Emotiva & Tonewiner); they draws you in A75, locking rhythm and timing together so naturally that resistance feels pointless. The midrange already a Klipschorn and La Scala strength, become almost vocal-centric and human, with voices floating free of the cabinets and instruments carrying body and harmonic density rather than edge. There’s a liquidity here that softens the horns without dulling their immediacy, allowing long listening sessions that feel immersive instead of fatiguing which is new for me in my set up.
Up top, the presentation opens my speakes up into air and light, giving cymbals shimmer, strings breath, and space between notes that feels expansive and alive. I think Thomas called it sparkle. My soundstage deepened, the image stabilized, and suddenly I was inside the performances. My overnight listening results were deeply emotional I evalated my A75 amp from 5PM to 4AM. The Galion A75 doesn’t just make my speakers sound better; it makes them sound inevitable, as if this was always the pairing they were waiting for. The music flows, time slows, and before you realize it, you’re sitting there in a quiet trance and the sun is rising and I was still just sitting here wiht coffe in hand...just listening. This isn't hi-fi fireworks this is Klipsch speakers being musicaly resurrected. I hope you understand my rants. Life is short do what makes you happy. If music is your passion look no further. Thank you Thomas your passion for audio is head and shoulders above the competition. And all this for $1500. MIKE DROP!!!

Honesty, Integrity, and Amazing Sound
Thomas represents a level of honesty and integrity that’s rare today. From the first conversation, everything was transparent, straightforward, and genuine — no hype, no pressure, just real knowledge and passion for great sound. That integrity clearly carries into the products.
I started with Galion speaker cables, and that alone told me I was dealing with something special. From there, I purchased the Galion TS P75, and I intentionally waited three months before leaving this review.
All I can say is wow.
The sound is amazing — alive, open, and incredibly detailed. It pulls you into the music and keeps you there. This is real performance, not marketing hype, and it becomes more impressive the longer you listen.
I now have the Galion Discovery Mono Block amps arriving next week, and I couldn’t be more excited. If the TS P75 is any indication, the Discovery Mono Blocks will be something truly special.
Galion products are worth the investment, and Thomas stands fully behind what he builds and sells. This has been a new discovery for me, and one I highly recommend to anyone serious about sound.

THOMAS?! COME-ON MAN!!! I was not ready to be 'red-pilled' like this. I purchased a set, to compare with my flagship Tonewinner class A 100 wpc/300wpc class AB. The Discovery Mono MONSTERS sent my Tonewinner packing immediately...no contest...instant acoustical enhancements. I connected them to my Anthem AVM-90 processor (Klipschorns La Scalas Eversolo A-8 streamer&Oppo-205 both with upgraded power supplies. The supreme and effortless bottom end instantly took my breath away! And you are correct. Highs sparkled just like you said! 'Airy soundstage', (if you know you know) and a darker/lower sound floor with deafening silence. Noticeable separation and enhanced deeper/wider sound stage. I closed my eyes and could sense the musicians vocals and their resolute instruments standing in from of my own private stage. WOW!!! After some heavy listening (F-22 aircraft take-off levels) to my usual suspects of familiar tunes. I had to prepare myself to be acoustically shocked and sonically transported with the mono signature sweetness! They breath really large and exhale velvety sweetness across the acoustical spectrum. THESE MONSTER DISCOVERY MONOs COMMAND ACKNOWLEDGMENT!!! They require lots of air and yes they ABSOLUTELY flex. They growl with luxuriousness and opulence like the dreamy throat rumble of dragon in Lord of the Rings hiding under the mountain of gold coins. These Discovery 'whose yo' daddy' mono blocks are not for the faint hearted! My speakers have never-ever been so alive, articulate and musical. As you know Klipschorns and La Scalas can be a bit anemic in the lower end...NOT ANY MORE! I now question the existence of my 2000 watt sub (turned off) that's the size of a medium fridge. Not sure how I feel about that. It cost me a pretty penny. Thomas your voicing of these monoliths is SPOT-ON!!! Thank you my, 'smarty-pants all-front-o-the-bus friend', for your incredible passion and customer service. What you've specifically done for me, I'll never forget. I claim for 2026 and beyond that the winds of success fill and never-ever leave your sails! Your humble customers for life. Ethan
