Anyone own one of these preamps ?

I own a Herron VTSP-360.  It's very dynamic and detailed, without being overly so.  It's very neutral, and does not sound "tubey".  More of a "straight wire with gain" preamp than one that will sound a certain way.  

I've heard Anthem preamps, but don't consider them in the same league.  IMHO, room correction is for home theater, but to each their own.  No experience with the other products mentioned.

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.
