Earlier this year my system included a Pi2AES hat streamer, Denafrips Ares II dac, NAD C375BEE integrated amp, Rythmik F12SE subwoofer, Def tech BP20 towers with the crossover capacitors upgraded and tweeters swapped for beryllium ScanSpeaks. I was curious about an upgrade and thought the preamp and power amp sections were the place to start. I wanted to preserve or enhance the following aspects of my system: airy top end with a liquid and organic presentation, good enough imaging and soundstage, especially when speaker positioning is dialed in, well integrated bass down to 20 Hz. The last few months I've auditioned a used [well respected tube preamp] and the TS A75 power amp.

I can say the following about the power amp: the timbre is fantastic and highly musical, the upper region is more airy and refined than what it is replacing while the mids and bass are wonderfully authoritative, it handles delicate passages adjacent to or intermixed with more eruptive moments better than anything I've heard. For each of my priority areas going into a new power amp this one exceeds them all, the proof being how often it's on and I'm listening and enjoying the music. I am very very happy with this amp.

For now, I am performing volume control on my phone upstream of my streamer and DAC, so the audio files are not transmitted bit-perfect. I am also connecting my Ares II directly to the A75 and can say the sound here is better than using either the preamp on my NAD integrated or the used tube preamp (not a Schiit Freya!... came with highly praised OS CIFTE 12AU7 preamp tubes and Philips 5R4YG rectifier tubes i will be taking it to a technician to check linear response and tube health, and the product is well known and well reviewed but I have not been able to get it to play nice with my system). I just heat shrunk two Gotham GAC-1 Ultrablue RCAs to use as line level connections to my sub, and am defaulting back to using a high level connection, but either way it integrates so well I'm not in a rush to get separate preamp outs. Hope this helps someone!

I am very bad at judging amplifiers because i cant put words on what i hear,if i like them i like them if not i dont.

This one i like,it´s one of the best solid state i have heard,and i have heard a lot.

Most so called high end amps are for me only high en to the name or as Mark Levingson once said 90% of high end is bullshit!!

It will not reach the sound of my Prima Luna HP same as PL400 that cost 6000$ in sweden.

But it comes very close but with a leaner sound,the prima luna have more guts but they both sound terrific.

This is a keeper ,period.

I dont know how much it differs from other chinese clone amps of Darzeel,Goldmund or Burmester,i have not heard them so...

I previously powered my Ascend Acoustics ELX towers with a Linear Tube Audio (LTA) Z10 integrated amp. While the Z10 paired beautifully with the RAAL ribbon tweeters for mid-bass to highs, I felt the low-end lacked the control and presence I desired, especially on amplified electric bass in fusion jazz and R&B. The Z10 excels with acoustic jazz, but for my broader musical tastes, including acts like Spyro Gyra, and Fourplay, I needed more low-end punch.

After auditioning the Heaven11 Billie and Vincent SV-500 hybrid amps, neither offered enough improvement to replace the Z10. Around the same, I discovered the Galion TS A75 amplifier. My interest was sparked by a review from Terry London. So I contacted company owner Thomas Tan and got a Galion A75 in for a 15-day audition.

Initially, running it direct from my Oppo 105 sounded good, but once I introduced my Audio Horizons 6DJ8 tube buffer, the A75 truly came to life. Its midrange performance was stellar, and the bass became tight, punchy, and controlled. Despite concerns from other reviewers about a "V-shaped" sound profile, the tube buffer seemed to resolve that, delivering a balanced and engaging sound.

In terms of price-to-performance, the A75 competes with far pricier amps. Its ability to render clear, distinct instrument placement and deliver satisfying bass makes it a standout. Having also owned and/or auditioned a few other amps like Channel Islands, Outlaw Audio, STA 200, Bel Canto, and Class D Gan 5, I can confidently say the A75 punches well above its weight, earning its place in my system. It’s a keeper, and for now, my "upgrade-itis" has been cured.

I've been listening to the TS A75 for a couple months now. Honestly, my system has never sounded so good. With excellent recordings, soundstage is more expansive, yet instruments remain well focused. I listened to an 'old chestnut' tonight - Miles Davis' Kind of Blue (LP) - I know it's cliché, but it felt like I could hear all the way to the walls of the studio. Like others have mentioned, there seems to be more space around the instruments; more air. It is quite impressive. Overall, I have also noticed more texture and detail in the sound. One set of recordings I particularly enjoy is Herbert Blomstedt conducting the Brahms Symphonies. There is so much palpable texture in the basses, cellos, and low woodwinds (especially bassoon/contrabassoon). Thomas, you have voiced a really a wonderful amplifier...Absolutely recommended. Thank you for making such a great product at a price more audiophiles can afford. I'll be looking forward to your preamp. :)

I have attached a picture of my system. Room is treated. Source is Analog or Digital. Analog is Project 'The Classic' Turntable into (DIY) VTA PH-16 tube phono preamp. Digital is Denafrips IRIS into Pontus II via I2S. Preamp is one of three: Freya+ with 1950's MELZ 6n8s tubes/LISST buffers (really a fanstatic combination, btw), Denafrips Hades, or Gustard P26 with Sparkos op amps. Speakers are Philharmonic Audio 2's (I am so happy to have these...)

Upon receiving the unit I immediately hooked it up to my system, it was dead quiet background, outstanding image focus and dimensionality, and a highly resolved mid-range. One of the best amplifiers I've ever heard with regard to focusing musicians in space convincingly. I paired it with Eversolo DMP A8 as a streamer, DAC and preamp in 1 and this amplifier is driving a pair of Kef R11, all has a pure and liquid sound. Can’t wait for this company to release a tube preamp to match the poweramp. All I can say is purrrfect!
