First tube preamp recommendations (under $5k)


Right now have di20he -> terminator -> he9 -> pass x350.8 -> ATC scm7 / NS5000.
I am thinking of introducing some tubes into my chain. I like the sound I am getting but want to explore what tubes can do to the sound (slight warmth, biggest soundstage, better layering etc etc). Don’t want to go to nuts on price. If price is over $5k would consider if its really exceptional (but for sure not over $10k). Totally fine with used. Balanced would be nice but not mandatory.
So far I am thinking RP7, EVO400, bhk. Any thoughts?

I've recently purchased a Backert Labs Rhumba and am using this with a Pass XA 30.8  Absolutely love the combination. I would also consider a Cary.
invalid I talked to the space tech labs guy and the 1 thing I didn't like he wasn't willing to show me the internals (he claims since he doesn't want people to copy him). Its something I don't like about mcintosh either.


Most audiophiles don't even know what point to point wiring is supposed to look like anyway, they think it's all the internal parts are supposed to be in neat rows, which isn't  point to point wiring, it's hand wiring but not point to point. True point to point wiring is almost a lost art very few manufacturers do it.

The Cary SLP-05 is a smooth dynamic performer with a huge soundstage.  It tends to be "phatter" and bassier, I really love the sound.  The Rogue RH-5 is more neutral and transparent.

I owned the Rogue RH-5 before I bought the RP-7.  It was a direct comparison.  The RH-5 was significantly more dynamic and energetic and was more transparent than the RP-7, which was a disappointment.  
I love Rogue Audio and had a cronus magnum ii for years but I have to call them like I hear them.  

A winning circuit design will sound better with cheap parts than a average circuit design with top notch parts.

Really? Ever build anything? There are no new circuit designs. There are only compromises. Just by putting in a V-cap will change the sound of any unit for the better. Audio Note non-magnetic resistors also. Been repairing and modifying and manufacturing components for over 20 years. I am able to hear every component mentioned in these threads. Repair or upgraded most all of them also so I can compare them. Just because a component is made by a so called Tech means nothing. I have repaired or rebuilt those components also. Not all of them are that good. Recently added Manley Steelhead and Tron gear to my experience. Expensive components. Not reference quality. You are comparing manufactured gear from one company to another all made to a price point to make money. Low grade parts and mostly poor to just OK designs. Nothing point-to-point which always sounds better.

Anyone in the NYC - NJ - PA area is very welcome to come hear what things should sound like.  You are welcome to bring you own components over to compare.

Happy listening.
