pass labs x250.5 or plinius SA102 for summits


i have started a 2 channel set up from scratch with a pair of summits. iam looking at the passlabs x250,5 v/s a plinius sa102.i am unable to audition these amps so any opinions/advice from forum members will be greately appreciated.i would also apprecite any tube preamps that
would be synergistic with the amps and the summits.

Would look for amp with extended frequency extremes summits have ample midband output, the plinius might be too much for the compression driver, pass isnt the last word in lowend control which that 15 will need, from what ive heard the jc-1 might be great. What levels do you need, if your not into 115 db, A good tube amp might be in order. Ive owned summits 4350 4435 L200 L300 L250 4320 ect. Favorite amp for those is a Crown Delta omega 2000 monos, 2K 2 ohms but sweet. I now own the plinius Sa250IV LOVE IT
i am sorry. these are the martin logan speakers and they have 200 amps driving the woofers.i live in texas and would prefer a ss amp with a tube pre.thank you for your response.
Charu: With the bottom falling out of the X350.5 market, you should consider the X350.5 over the X250.5. I have a pair of Summits arriving next week. They are replacing a pair of Prodigys which were driven by the incredible JC-1s. Since the Summits have on-board ICE amps for the woofers I didn't think I needed the power of the JC-1s so I traded them for an X350.5. I've heard from other Summit users that the X350.5 is more than adequate to drive the Summits. If you're still not sure contact me off list in a week and I can give you more details.
Veloceracing,

Boring question - could you compare JC1s to Pass X-350.5, soundwise? Any palpable difference relating the power slam? Any interesting point?
Zormi: Regrettably, I can't answer that question until late next week when the Summits arrive: I've been speaker-less for a while. I can tell you, though, with much certaintly that when I compare the JC1's to the X-350.5 in the "off" mode with no speakers attached I can't discern any difference sonic or otherwise. OK, just joking .... I should say that I've never heard the JC-1s powering the Summits, nor have I heard the X350.5 powering the Prodigys (my older speaker) so I don't know if I'll be able to provide a good comparison since the speaker/amp combo will be new to me. But I'll try to theorize ...
