Review: Parfait
Review: After a bit of a rough start, which the guys at bellari solved without any hassle, I have been using this device as a phono preamp on my U turn orbit turntable with very pleasing results. My turntable came with an integrated preamp that worked ok but was a bit on the quiet side for my system. After looking at several options, this one seemed to have everything I was looking for at a reasonable price. It had volume control and looked nice. First thing I noticed was the built quality. It is very solidly build, and very pretty in my opinion. Reminds me of a US made product from the 1950s. Its all thick sheet metal. The knobs seem high quality too, as they turn very smoothly, very nice feel to them. Sound quality wise is overall very good. I am no audiophile and my system is not exactly very high end but I am enjoying how it sounds very much. There is maybe a tiny bit of harshness on the high end when compared with the old integrated pluto pre amp, but I can basically only barely detect that when using my headphones and listening carefully. Everything else is just better. The bass is sounds fuller and deeper even at the 0 position, and it can get very loud. I am now using with the volume knob at a bit more than halfway and it is way louder than my old pre amp, without any distortion. The noise floor is even quieter as there is no hiss heard at high volumes like my previous pre amp had, even with the volume knob at full. You need to ground it for it to get this quiet though. Uturn says that components connected to their turntables dont need grounding but I find that to be not true. I used the pa550 without the ground wire at first and there was a small hiss, this completely disappeared once grounded. For the price this is a great pre amp. It not on par with my friends nakamishi ca 5, but thats a thousand dollar component. I am now enjoying my records much more.
