What's your "diminishing returns" preamp choice?

Whatever Ralph, believe what you want.

I am not an expert like the rest of the folks who are posting but would say that a preamp shopper needs to try a PrimaLuna Dialogue Premium.

Hand wired, dual momo, many available replacement tubes, etc., etc. for $3K new.

this is the best my system has sounded - Maggie 3.6 and DWM bass panel, Ric Schultz modified Oppo 105, and W4S amp.

Yea, I know it is my current preamp!

Enjoy the journey!

I've lived in the no preamp is the best preamp and passive worlds. Both provided happiness and long-term satisfaction. I think everyone should experiment, as despite what anyone claims, those options do offer the best solution for many people. Or, many people at that particular junction in time...

Now, playing along that you want an actual preamplifier, my vote for "diminishing returns" preamplifier goes to the AES (Audio Electronic Supply / Cary) AE-3. With the statement that different components perform better or worse depending on the system they go into out of the way, I've seen this little preamp sound flat out amaze people. In fact, as good or better than some that if mentioned here would react like throwing gasoline on a fire. My only reservation is that it doesn't include a phono stage for those who require same.

Woofer72, I have been going through somewhat of a "final" pre-amp search myself. It is the ONE component I would pay more for to find a notable improvement. Generally what you get with more expensive designs is larger power supplies, better parts and construction but I really believe that in conjunction with that what is equally important is the simplicity of the design itself which can make many lower priced preamps really make you question how much to spend.

I really have been enjoying a Supratek Syrah for many years with little interest in pursuing the upgrade path full well knowing that there IS better BUT I recently changed amplifiers and the seed of change is planted and I am also looking, considering numerous options but far from settling on anything as of yet.

One thing I would bring to your attention is the Odyssey Candela. What I REALLY like about this preamp is the fact that it is a budget priced linestage at around 1.6k with pretty lofty performance at its price. I would describe its sound as warm, VERY resolving with well defined image outlines but most importantly, an SET like tonal presentation, really drawing you in. This is but an example of what might be out there. The Dehavilland or possibly a used Cary are other excellent considerations as well but this Odyssey REALLY caught me by surprise, lent to me by a friend. It's hands down better than another 4K preamp I directly compared it to and the linestage is better than the Supratek. On the other hand the Supratek has a great phono stage and excellent dynamics, probably the best 2.5k I've ever spent on an audio component. You might want to try their free home audition. Its hard to imagine you wouldn't like it.

You are correct about the power supply. The best preamp will be battery powered (IMHO).
