Anyone own one of these preamps ?

I had the Anthem STR Stack (pre/amp) and loved it! Yes the ARC is great for home theater as referenced above but it was also very handy for my 2.2 system. I am able to tailer the sound to how I like it and is has great bass management when using subwoofers. It has a ton of connectivity for pretty much anything and the internal phono stage has a lot of options of adjustment as well. Now I will say it takes a little tech knowledge to tweak things but you can do a lot with it. It has an app to make things a little easier if you like that too. 

Every enthusiast has bias’s, preferences and kit. This might generate some controversy (not intended) but here goes: with over four decades in this hobby, and recently converted a number of friends to join, I have heard a lot of systems and preamps (though certainly not all) including: cj pv2a, cat sl1 mkii, arc sp10 mkii, ch precision, etc. but most recently the latest Herron 360 was in my system (hoping for synergy with my herron VTSP-2a phono amp) and sounded fantastic.  I recently A/B it with a CJ GAT and couldn’t decide on my preference.  That being said, I sold it a month ago in favor of a much, MUCH cheaper alternative which I preferred sonically.  That is a DiyAudio korg nutube B1 with modifications.  A number of years ago, I was fortunate to meet Nelson Pass at his place and listened to various FirstWatt and Pass components. He made a change in the kit we were listening to and I was stunned- It was the precursor to the Nutube B1.  I have been playing around modifying the B1 build and have landed on my current reference.  A B1 with an outboard linear power supply, 6 high end caps (jupiter, mundorf and clarity) and taking as many switches (eg- on/off switch out of the circuit) because the Lps provides that and the nutube biased around 10.2 vdc.  Total cost around $750.  Rest of the system is a VPI TNT w/ 12” arm, zyx cart and pre-pre, herron phono, nutube B1, CJ Premier 11xs (triode) and spatial X4’ modded to 16ohm.Couldn’t be more pleased.  I know DIY is not for everyone, and I am no EE, but an interesting alternative for the adventurous.  Thanks for reading.

@stevehardy1 I made the same upgrade with the same result, everything about the music is dramatically better and just keeps getting better the more I listen.  At first I didn't know if it was a 6 grand difference, but now I am glad I made the change.  Highly recommended.  

I’m going to recommend the PS Audio BHK preamp. They can be found refurbed on PSA website and used in the $3K range. It’s an excellent piece. 
If you don’t need balanced connections the Galion P75 is another excellent option. 
 

if you want a workhorse solid state preamp with excellent functionality the Schiit Kara is my recommendation. 

I have a Herron Audio VTSP-360 Ref ESP. The most recent preamp I compared it with in my system was a NAD M66. In terms of user ergonomics, always somewhat a subjective thing, I found the Herron to be superior and much less idiosyncratic than the NAD/BluOS UX. In terms of sound quality the Herron is significantly superior, despite (or maybe because of) all extra bells and whistles of the NAD.  

In the past I've also directly compared the Herron 360 to an Aries Cerat Incito S and a Conrad Johnson ART 88 preamp. Both are significantly more expensive than the Herron. Yet both were eclipsed by the Herron in terms of  sound quality as well as user interface. Plastic remote control and all.

The Incito S could be quite thrilling on a small subset of the music I listen to, and could be fatiguing on anything with a hint of excess treble energy. And I tried quite a bit of tube-rolling and bias setting with the Incito that only partially tamed it down a bit. The Incito S build quality is Tesla Cybertruck bad -- bolted together stainless steel panels, loose hardware, overall looking like a not very good DIY project. And monstrously big and heavy.

The CJ ART88 is bigger, heavier than the Herron and harder to get into for tube changes. It has a higher noise floor even rolling in some NOS Telefunken 7DJ8s and to my ears did not offer any significant sonic advantages over the Herron. Volume steps on the CJ are larger than on the Herron and often seemed to be either just a little low or just a little high with no in-between that was just right.

Despite being retired, Keith still is available to support his products and the last time I spoke with him he said he has had no failures of the VTSP-360 in the field and considering the way he built them, he doesn't expect any, other than a tube needing replacement now and again.

My experience, for what it's worth.
