Belles preamplifiers -- experiences at different levels?

I have owned a VT-01 preamp and tried a few different tubes. It was OK, but nowhere near the resolution of my Benchmark HPA4. But then that's probably the tubes vs. solid state debate, and I don't wish to open that can of worms.

@koestner I'm really only interested in his SS. I have my end game tube preamp.

LA-01's are not often found any more. People who have them know what they have. If you see one don't hesitate.

I’ve just acquired a Belles Signature duel mono preamp (2025).  I’m using XLR connections with my AR DA 400 amplifier. It’s the most beautiful preamp I’ve ever heard.  All XLR from dac to amp.  It’s stunning. 

David Belles has made a lot of great gear over the years. I have a Belles 21A released in 2003. It's a wonderful sounding preamp. I've had it in storage for several years, but your post is encouraging me to bring it out and give it a listen.
