First of all, Raul wanted me to listen to the Essential, not do a comparison between it and my Aesthetix.
We disconnected both of the Aesthetix units and set up the Essential before our listening session.
Aesthetix has been my reference for 7 years, Raul wanted the 3150 plus the rest of my system, so we were both OK with skipping the Aesthetix intro.
I judge only with my ears, not the numbers. The Essential is an excellent preamp-phono and although the specifications are impressive, that says nothing more about it's sound than the specifications of a Yamaha integrated or Boulder phono (both of these, typically a decimal point followed by multiple zeros as a distortion spec).
My psychic mind tells me Albert Porter had a serious reality check...
Psychicanimal, if that happened, I didn't realize it. Thanks for the update.
I hope to listen to the Essential again. Raul and I discussed that possibility and I offered to do some product photography as Raul has no professional images. At that time I could listen longer and in a relaxed mode and maybe even write a review at Positive Feedback. I can listen to a piece like this and rave about its merit, regardless if it qualifies as a replacement for my Aesthetix or not.
I think anyone who's read much of what I post here, I rave about Vandersteen, Kharma, Maggies, Quads, Avalon, Dynaudio, Martin Design and Evolution Audio (to name just a few). Does this mean I plan on selling my Dali Megalines and move to another speaker? .......No.
All those brands are superb designs but none of these speakers are necessarily better in EVERY area than every other one on the list. Each has major strengths and a little weakness and each represents a particular designers shot at perfection. There simply are NO perfect pieces in audio, not my Dali's, not the Aesthetix, not any brand spoken of in these forums.
However, I am not surprised when someone claims one of these as "best," or at least the best they've ever heard.
Not surprising, as they are all within the top tier.
As for Raul:
I reserve my opinion about the Essential 3150 quality sound reproduction against not only the Aesthetix one but about any other phono-line-preamp. This not belongs to my targets and I'm not the right person to do it because the Essential 3150 is an important part in the José and my life and we could have some bias in favor of the Essential 3150.
I would hope Raul would have a bias for the Essential, it's a project he is passionately involved in and the end result is a beautifully designed and built unit that I think will find great success.
There will also be people who prefer EAR, CAT, BAT, Aesthetix or ARC simply because these tube designs perform so differently than transistors. That is part and parcel of the high end business and neither confirms nor denies Raul's passion or the value of the Essential.
I look forward to another session with it, hope that happens as we discussed.
