Review on 🔊 Bellari PA550 Preamp by Crystal Palmer

The Bellari PA550 preamp is well built and sounds great, but there are a few things to note. First, there's no power switch, so you'll need to plug it into a switched outlet or it'll just stay on all the time. The second and more annoying point is that the audio inputs are not isolated from each other, so there is a lot of leakage from inputs 1 and 2 to the phono input. I like the bass and treble controls and the headphone output. Connecting this preamp to a pair of Dynaco Mark Three 60 watt tube amps is primarily for volume control, and also because this preamp has enough power to push these amps to their full potential, unlike some of the cheaper amps that are I have tried.
