What medium priced amplifier is best with vinyl?

Johnnyb53 and Bobgates - I'm wondering if you saw much improvement with the Cambridge 640P as compared to the phono stage of the Onkyo A-9555. I have the A-9555 and have found the phone stage to be pretty good so I am wonder how much of a differnce you noticed? Thanks.

As my previous post mentioned, since I already had the 640P, I just set up my Onkyo with the 640P from the beginning, and never really gave serious consideration to the Onkyo's phono stage until tonight.

Your question continued to stick in my craw, so tonight I bypassed the 640P and plugged my Technics SL1210 M5G with fluid damper directly into the Onkyo. All I can say is YOWZAH! In my setup the built-in Onkyo phono stage is better than the outboard 640P in every way.

I suppose it could be a capacitive loading issue. The direct plug-in to the Onkyo sounded more relaxed, more delineated, and especially had much more ambient detail retrieval. It also lost some midrange glare and hardness that I'd been hearing through the 640P that I'd been attributing to other factors up to now--a direct drive TT, an Audio Technica cartridge, a switching amp, etc. But it was the Cambridge and it alone.

Even if it's a capacitive loading issue, it tells me that in this case the Cambridge is more trouble than it would be worth. I had connected the Cambridge to a line level input on the Onkyo with a pair of AudioQuests made of single crystal six-nines copper, and AQ is well known for musicality and low capacitance in their interconnects. One meter of AQ shouldn't have made that much difference in the capacitance anyway.

So save your money and enjoy your system!

I agree with you completely. I actually tried a Bellari VP130 in my system but quickly disposed of it because the Onkyo was clearly better.

I like the Onkyo suggestion.

Another good choice in that range might be a second hand Musical Fidelity Integrated.

Or how about a tube hybrid like the Unison Unico, or something tubed and digital-ready with a nice built in DAC even like the PeachTree Nova?

I had a Musical Fidelity integrated, and have heard several of their integrateds at the local high end store, and I like the Onkyo better. Personally I hear a little bit of midrange glare in MF amps and most Cambridge components as well, which is completely absent in the Onkyo, while the Onkyo matches or beats them in low noise floor, transparency, and low level detail.

I heard a PeachTree recently and was very impressed, both for its linestage and its built-in DAC. I think the PeachTree is a great choice for a small digital-based system. Teamed with a Wadia iTransport, it can make an iPod sound breathtaking when playing lossless files.

The OP, however, was looking for a good amp for a vinyl-based system. For under $800, you can't do better than the Onkyo, Another alternative would be the Denon PMA 2000IVR. Some owners swear it has one of the best phono stages they've ever heard, certainly in an affordable integrated amp. The Denon is certainly a different beast, weighing over 50 lbs. and needing about 4" of cooling clearance on top and sides. It also has a big footprint and won't fit on every rack out there. Still, I bet it sounds sumptuous.

Even if you got a Cambridge, you'd have to get an outboard phono stage, and when it comes to that, the one built into the Onkyo is better. I find Cambridge integrateds to have a bit of glare like the 640P does.
