I have a Galion TS A75. I've had it since February 2024. Customer feedback is 4.98 out of 5 stars, based on 102 reviews, which includes my own personal 5-star review. Plenty of independent positive reviews on YouTube as well. The A75 has been powered on in my system all this time. In over 20 months, I've never had any problems. Beautiful sound, doesn't run hot, dead silent, built like a tank. I like that it has both XLR and RCA inputs. I'm using it to drive my more insensitive speakers, currently KEF R3, or Cabasse Murano, whatever is in rotation. (My more sensitive speakers are all driven by tube amps.) The TS A75 sounds way more powerful than its nominal 75W suggests. I have 200W+ GaNFET amps (LAIV and PeachTree), and the A75 easily keeps up. Sounds strong and clear. Perfect bass (no sub needed for music) and extended yet smooth highs. Some people (including Thomas & Stereo himself) claim that it's a bit V-shaped. However, I do not think that it lacks in mid-range. Talking about Thomas, I have had quite a bit of interaction with him, and he is extremely responsive and supportive. An honest, knowledgeable, and hardworking gentleman. The TS A75 is a "no frills", solidly built power amplifier with a great sound signature and punches way above its price point. Please note that the sound of your power amplifier is very dependent on your source and your pre-amplifier. I'm using either LAIV Harmony or Vincent SA-32 preamps, and both sound great. I haven't bought a Galion preamp yet, because I'm waiting for one with XLR connections, as I run longer cable lengths. More info: https://www.galion-audio.com/products/galion-ts-a75-power-amp
