Your tube preamp and ss amp thread

Over the past year, been using a Audible Illusions L3A with a combination of SS amps in this order. 
McIntosh MC152
Rowland Model 12
Pass XA 30.5
and now a Levinson 532H

All combinations sounded good to my ears. I’m interested in going for an even blacker background which I think there could be limits with a tube preamp. Kind of a trade off between detail with a SS preamp or a musical tube preamp presentation. I’ve read reviews that the AI L3B provides that blacker background but that’s going to cost me another $3k, so I might change out tubes on the L3A for now to hear what happens. 

I run Meixing Ming da MD90's monoblocks with four KT90's a side, using a Yamaha as1100 as a pre amp, which also doubles as an integrated amp. This is essential to troubleshoot the system and tubes when needed. Thankfully my system has been stable for a couple of years now.

Ayon S-10 Mk 2 Signature
Karan KAS 270

Rouge 99 Magnum
Mark Levinson No. 436 monoblocks

Right now in my main system I'm running an Aric Audio Unlimited pre, with a First Watt J2.
