KT150s in a Preamp Design?

I've used 3b22/1616/3b28/866a in my space tech labs rectifier. They all sound different, the 3b22 has great instrument separation but sounds a little harsh like solid state, the 866a and 1616 sound the best smooth detailed dynamic sound with a big soundstage.

Hey I'm interested, and more so if you actually try it and compare KT150s to 6SN7s in a preamp.  I run four 6SN7s in my preamp and four KT150s in my mono amps. 

Have wondered who's actually tapped the real potential and ceiling limit of a KT150 tube in different ways. Let us know if you do.   

I believe you can use EL32 tubes in that particular preamp as well as kt150.

I been looking at their tube EQ for a while. I like tone control and that EQ with a balanced passive pre, Tape and LP playback heaven. I like the options too. It has a bypass and can loop right in with phono/tape preamp.

Gives a balanced option for a Reel to Reel,  XLR to record..

4-6k for a Manley.

These guys Under 2k, I just wonder about crosstalk? Balanced though.

They have good reviews on their passive with remote too..

What's their lead times? Anyone know?

I like um...
