Pass XA-25 Review (Part 1) from 6Moons. http://www.6moons.com/audioreviews2/passlabs3/1.html And a nod to our very own @teajay also : ) |
"After 25 watt in class A, does It switch in a/b?? How much is its Power in class a/b??" I think the 80W@8R and 130W@4R are the class AB continuous RMS limits, with "class A" envelope extending to 50 watts. Most class A push pull devices have a considerable transient overhead above their class A power ratings into class AB, as much as 5-8db. |
Has anyone tried the XA25 with a Spendor D7? It’s 90db, but stereophile found the actualy efficients of the D7 to be 89db. I do like to crank it at times, so wondering if the XA25 has enough juice. Based on the actual power ratings I think the answer is yes. I’m in a smallish room (13x13) so that should only help. Planning on pairing it with a tube preamp like the Backert Labs Rhumba, or Primaluna EVO 300/400. |
Has anyone tried the XA25 with a Spendor D7? It’s 90db I use Acoustic Zen Crescendo II's with the Xa-25. They also spec at 90 dB and measure 89. The impedance curve is pretty benign, never below 5 Ohm's, a bit like the D7's. They'll go regular stupid loud, maybe not drunk stupid loud, in my 15 x 25 room. Sound is fantastic through a Herron VTSP-360 with REL S/5 SHO. |
