Suggestions for a holographic preamp?

@barts - thanks, but I specifically asked Keith Herron if a universal remote could be taught on this and he told me no, and I don't think it's because he wants to sell a few cheap remotes.

@cfarrow - yes, that ESP 360 is what I've got as well, and I upgraded the tubes via Brent Jessee. I love its sound, but I really hate that remote! I may try a few of these that have home-audition and see how they compare in my system and my listening environment. I will not be letting go of my Herron Phono VTPH-2, however! 

Also, can anybody tell me anything about impedance matching between pre- and power amps? 

In general you want the input impedance of the amp to be 10x the output impedance of the pre.  BUT, the impedance varies by frequency and may go higher or lower than the stated number, so to be safe I’d look for the input impedance on the amp to be at least 20x the preamps’s output impedance if possible.  In general I think this is more likely to be an issue with tubes than solid state.  Hope this helps.

The Spatial Audio Raven is off interest to myself, I would really like to experience it in use, hence, no ears in front of it does not encourage me to strongly suggest it can make a very good impression as has the EAR 868 has in a system belonging to another.

Synergy is what really matters and this is only to be found through trialling different devices in the home system within the dedicated listening space.

Not one recommendation or suggestion of investigation is going to bring the impression Synergy can create for an End Sound produced as a guaranteed outcome.      

OP,

My recommendation is to try out Linear Tube Audio Microzotl. This is my pre-amp and for me, reproduces a holographic image well. As some had posted above, get their level 3 upgrade and it falls within your budget. One thing the Microzotl does that other Tubes amps may not (or may) do, is that it sounds like a cross between a Tube and solid state. I.E. It has details in the music and yet it has body on the instruments and singers. 

If you claim that your existing gear already has the ability to create space and dimensionality, then the Microzotl may be a possible candidate. Check out their website and see if the remote is up to your standards.

hope you get the right one. and please let us know what you get

@pindac - you are absolutely correct, which is why I'm soliciting many opinions as well as checking reviews and forums. 

@joeycastillo - MicroZOTL is one I'll be considering, and I see they have a 30-day home tryout. 

Spacial Audio Raven has a 45-day return policy. 

For new gear, Backert has a 14-day trial on a Rhumba Extreme 1.4, and PS Audio has a 30-day trial for the PMG Signature.
