Would a Pass Aleph 5 be able to drive Thiel 3.5 ?


I have a Threshold FET-10e pre-amp and a pair of Thiel 3.5 speakers. Currently, I am using a Bryston 3B-ST. My source is mostly CD based using a Esoteric P-500 transport and a PS Audio Ultralink II. I plan to purchase a Pass Aleph 5 to replace the Bryston. Would this be a good idea ? Would I get any improvement ? Any help on this would be greatly appreciated. Thanks.

I currently own Theil 2.3's and a Pass Labs x-250(synergy):) I have listened to most of the Thiel line up past and present. Before upgrading to the x-250 I was using x-150 again synergy. When auditioning the 2.3's I compared the aleph 2's vs the x-150. I personally preferred the x-150's. The x-150's goto 15 watts in class A mode. The x-250's goto 40 watts in Class A mode. The smaller amps I compared them to were absolutely terrible; not enough power. Now my Thiel's sing:0 Also owned the x-2 preamp and it is 90% of the x-1 which I know own.
At low level volumes I think it would, but i would opt for a higher power amp. Classe are know to be good matches with the Thiels like the CA 201.
FWIW and years later. . .

I have an Aleph 5 which I purchased to drive some now "set-aside" speakers. I purchased for the third time a pair of Wilson Watt/Puppy 5 speakers (can't seem to find anything I like better long term).

While the W/P 5 are not quite as inefficient as the Thiel speakers in general, the WP's are still a demanding load (ignore their efficiency rating of 94db) as they make wide swings from about 1.5 ohms and up.

The Aleph 5 (stereo amp, 60 WPC) sounds very nice with these speakers for my listening habits, room and volume levels. However, I was recently auditioning a Gamut preamp in my system and found that when I turned the volume up well past my normal "loud" listening levels, the soundfield congested.

I suspect this was mostly caused by a combination of my room and the available power from the Aleph 5 amp (I think it just ran out of juice). Now this being said, this was a listening level well beyond what I would ever sit and listen to for any length of time.

The Aleph 5 is rated at 60 watts class A. I don't know what it really puts out. Nelson is pretty conservative with his ratings. I also don't recall what this amp does in 4 vs. 8 ohm conditions.
