What is the best phono preamp you have heard?

Jeff Rowland Cadence sounds better even using entry level
table and cartridge than any other setup I have heard
regardless of the price
The music arrives from dead silent background
it is coherent and inner detail is to die for, the cleanest
Ive heard, but If you know Rowland gear you know what Im
talking about

I loved the Aesthetix Rhea. I ended up buying the Conrad Johnson EV1 though, and it's marvelous, especially at its price point. I haven't heard the Boulder yet, but from what people have told me it's the most amazing piece of gear on the planet. The local Boulder dealer, who also carries Aesthetix and BAT, told me point blank "Do yourself a favor and don't listen to the Boulder. It's THAT good."

So far the Hagerman Trumpet with NOS RCAs.

I have heard the Aesthetix IO signature but I would not list it as the best I've ever heard.

I have heard the Boulder briefly, but seriously, $25,000??? If I had the money I would still not buy a $25,000 phono section.

The Rhea is good, but a little too noisy for me.

The best one that I've spent any time with is the Pass Labs X-Ono.

Based on information I have gotten directly from friends who are owners of the Manley Steelhead I am think seriously of buying one.

So there, you have another post that really doesn't offer much help...

I notice that alot of people speak highly of the Aesthetix products in this thread, i have been looking for a new phono pre, and have found an estate sale that is selling alot of high end stereo equipment, and i can pick up a
Aesthetix Callisto Signature, for not much money, has anyone heard this particular preamp, and would it be worth $900 ??
