Dynaudio C1 and Pass amp

Hi Keithr,
I already have the XA30.5 and C1 Sigs are on the way as well. I shall find out soon enough. If X250.5 is indeed more "suitable", there's always Reno Hifi to move "up". :) But looking at the numbers from Nelson's Leaving Class A article, XA30.5 seems to have higher bias current and higher class A peak - 1.3 vs. 0.8 and 57 vs. 20. I'll make sure to report back how XA30.5 drives the C1 Sigs in my big room.

Hi Paul,
Good to hear from you again. To be honest, it is your review of C1s that made me start looking at them. It has been awhile when I first stumbled upon that review, but Xti just reminded me the other day to read it back again, which I did and gave me a whole new perspective.
I used to have Bryston 4BSST2 but XA30.5 is just at another level entirely in terms of refinement and seduction. I didn't get to test them out driving difficult loads however, as my old Electra 1008 Be2s were quite efficient. Both amps drove them with ease.

Best,

Since the Dyno's are a 4 ohm load it is important to find a mating amplifier with plenty of current capability. It is not really about the so called amplifier 'power' because that does not tell you much about the amps ability to drive current into low impedances.

Interesting thread as I decided to go with a similar combination.I recently heard the Pass XA 30.5 with the Dynaudio Anniversary 25, which have similar specs to C1s and C2s. They sounded wonderful together. The Pass easily handled the Dynaudios even at loud listening levels. I was so taken by the combination that I ordered the XA 30.5 on the spot to run my Dynaudio Confidence C2 IIs. The dealer assured me the XA 30.5 would be sufficient. I had come into the store inquiring about the X350.5, which is more expensive, but the dealer suggested I give the XA 30.5 a listen first. He obviously could have sold me either. Pass is shipping the amp next week, so I will be able to assess in my own room with the C2s soon, but based on what I heard, I am optimistic that the XA30.5 will be able to handle the Dynaudios.

I have XA30.5 and Dyn Special25 (88db/4ohms)
Wonderful combo!
No problems with lack of power. The needle on the pass never bounces.

Hi Pnmeyer,
Keep it posted how it goes. C2 II and XA30.5? I thought I was optimistic. But I guess it depends heavily on the size of the room. With C2 II though I don't suppose your room is remotely close to small at all.

Phreak12,
How big is your room?
