Tannoy Everyone?! with Leben CS600 or Pass XA25/30.5?

@pdreher I feel you. I used a Cary 306/200 for many years - the BurrBrowns were hard to beat! A good friend uses the same DAC and loves it too. The 3V may have been all I needed, but I'm skeptical. Bass and dynamics loss, congestion/breakdown with "busy" passages - particularly around the top edge of female  vocals and no room to move after 1100 on your dial - HEY don't touch that dial! Commercial free zone. JK. Anyway, I'm excited to find something new and reengage with happy, happy listening. It's a big drag with nothing to power the Stirlings...even for a day!

The triode mode works well on the Evo 400 for even less efficient speakers but does well with the 93db Tannoys. This wasn't the case for the Dialogue Premium I had before. I use triode for a few harsh LPs but tend to keep it in UL.

Pass XA25 will put out over 80W AB.  I don't like that sound.  If you stay in class A, it is a forever amp.  I tried to find an impedance curve but couldn't.  Adding a sub with a crossover point less than 100 Hz will take load off your main amp.  I bet the 25 will work then, There are other benefits as you well know.  Good luck.  Once set up you will have a beautiful sounding system. 

Ok, I have settled in and see two options, both keeping in mind that if a pair of Dynaudio Confidence 3's show up, I want to be able to accommodate them. In the meantime, I'm loving the Tannoy sound and the Stirlings are staying for some time.

1. Supratek Cortese (I've wanted one for 15+ years)

+ amplifier TBD 

Pass XA25 and Rogue Stereo 100 are both contenders (I know, I know...it's tubes), but I feel like they're sort of temporizing.  

- a Gamut D200i might be the things down the line if/when Dynaudios appear.

2. Accuphase E480 w/phono card.

I may be discounting the PL and maybe I shouldn't, but it also feels like a temporary solution.

"From looking around, the 30.5 seems a little rounder than the .8 with the 25 being the warmest of the three. Hopefully, someone's tried one or more of them with some tannoy Stirlings or Turnberrys (Turnberries?) and can weigh in."

I can weigh in. I had a Pass XA-30.5 and Pass XP-10 with Turnberry SEs. It was not a great combination. Not very dynamic. Much better results (with Turnberry) using an MC-275, Yamaha AS1200, and Benchmark HPA4/AHB2 (amp in use now). Maybe there was something wrong with my Pass amp. But I sold it to an audio engineer at Apple and didn't hear back that he was unhappy with it. Don't know what speakers he was using .....
