“This Vincent SP-332 is an extremely nice amplifier with plenty of power to drive my KEF R11 tower speakers. it is not harsh by any means and amplifies the input signal cleanly throughout the frequency range. It has that tube "warmth" feel to it. As a hybrid, the tubes do need to break in at first and they need to warm up upon power on. I recommend turning it on in the morning and leaving it on. Seem like it sounds better the longer you have it on. Love the VU meters and the choice of backdrop light colors so you can match to the rest of your system. This amp is very attractive IMHO. I've only had this for a couple months now and really need to test it with an 85 or 90 dba output someday. It barely takes any effort to run my KEF's at 75 dba. It's certainly a unique amplifier and I really like it so far.”
