Cayin A-88t vs. Almarro A318B

I've put a Black Treasure CV181-Z tube in the 6SN7 tube slot and was blown away with the results.
The sound stage opened up by a huge margin. Width and depth.
Tonal ballance is perfect and the extention on both ends are increadable.
I'm using a Tung Sol 6SU7 for my 6SL7 tube.
I'm in heaven.

The Almarro has warmer lusher mids, and the Cayin is more dynamic. The Cayin mids are also very good, just not equal to the lushest ever mids with the Almarro. Choosing between the two depends on your preference and speakers needs and the overall effect in regard to your system on balance. Neither is superior. Just different. And both very very good at what they do.

I tried driving some Sonus Faber Grand Piano Home speakers with the Almarro 318B. No can do. The bass was boomy and the bass clipped/cut-out/buzzed with anything other than soft background listening levels. However, I have heard the Almarro works good with Acoustic Zen Adagios and most speakers that are not power hunger like the Sonus Fabers.

I own Fritz Carbon 7's (87db) and I'm interested in pairing them with either the Cayin A-88t or the TAD 1000 mono blocks. Does anyone have experience comparing either of these?
