Best Full-Function Preamplifier

This is an interesting subject - how to get maximum performance for $20k buying new preamp and phono stage. Just because integrating separates is more difficult doesn't mean that the result cannot be better. But maybe within this price level it would be at least not worse to get, as suggested, full function preamp from VAC, Atma-Sphere or CAT.  I am not sure what I myself would do.

All helpful discussion and suggestions so far. I agree (conceptually) that placing it all in one box has advantages, thus the question. I'll take a closer look at the units mentioned.

It depends on whether you're looking for a fancy piece of gear so you can impress people, or just want a good preamp so you can listen to the music. I say don't waste your money. Find an Apt Holman preamp, have it gone over and then enjoy the music for around $1k. Two phono inputs, both MM, one with adjustable capacative loading. Tuner input plus two Aux; two tape monitors plus External Processing Loop and two outputs. Not beautiful but, in my opinion, an exceptional piece of gear.

@vinylshadow re:Townshend Allegri Reference Passive Preamp

Do you have experience with that or have you owned it? I am very intrigued by it. I have a good passive line stage that I used for years up until about 6 years ago. I still own it and it’s a backup. What can you tell me about the Townshend? I was interested in the Tortuga passives but they apparently have stopped selling them assembled and only sell some kits.

Thanks!

I've recently purchased it after reading several reviews and talking to John Hannant at Townshend. 

I am still in the middle of a big system upgrade including the ASR Basis phono pre and many Townshend cables and Seismic Isolation devices so unfortunately I have not utilized the Allegri yet. 

The Passive nature was a big selling point but the reviews that I continue to read are Stellar. I guess I projected my anticipation in my OP....

Good luck!!
