New Pass Labs X.5 series versus previous X series

I've listened to both the Pass 600.5 and the 350.5 for a good amount of time on each. I ended up with the 350.5 as they fit my budget and space constraints. They are both very robust in thier presence. You can really tell the difference between the two as the 600.5 really had alot of power all accross the spectrum and would probably drive the hell out of some good line source peakers. At 155lbs each they were formidable giants in my living room when I auditioned them for a month. But when it came down too it I got a great deal on the the 350.5's and the fit nicer into my salamander rack. As far as a loss in performance between the two I would say that the the 350.5's are are about 15-20 % less in performance than the 600.5's. They still bring a smile to face when I think about them and if I do a major remodel to my place I will definately make more room for larger amplifiers, just in case I score really sweet deal like I did on the 350.5's in the future. OOps almost forgot to mention that previously I had owned the 100watt Aleph O's and the X.0 pre-amp. also Martin Logan Statements.

Magichandslarry, did you perceive any other difference between X350.5 and X600.5 except for power? Please elaborate. What is the rest of your system? What music do you listen to? 

 

Hi, I'm wondering the real differences between the x600 vs the x600.5. With quite a bit of price difference, can anyone tell me if the x600.5 is worth the extra $$$. Thanks all.

Pass Labs is introducing a new series of amps, dubbed the XA.5 series. Some initial details on three of these amps have been posted on the Pass labs site in the last few days: XA330.5, XA60.5 and XA100.5. They seem to differ from the original XA series in that power doubles into 4 Ohms and input impedance has been raised to 30KOhms. See:

If anyone has any further info or listening experiences, please do post them here.

Hey Guidocorona,
I am currently using the 350.5's with my Wilson 5.1 speakers and they are doing a great job. I have been wondering about the Magico system 6 but I'll have to save some pennies. The 350.5 vs. the 600.5 well I'm not one for monster trucks but I do like Cadillacs especially the STS so hmmm.... how do I quantify the performance? Pass makes awesome ballsy amplifiers. along with my Watt 5.1's and my MIT Oracle V2.1 I feel that I have amassed a great set of gear. But as all audiophiles know technology marches on and I am curious about the Watt 8's. I am also curious about MIT's new Dot 2 upgrade. I'd like to know if anybody has heard a similar set-up? Any way I feel like I 'm rambling about my gear which always seems to be on my mind. I always seem to hear the words of grandfather in my head when I think about getting new stuff. He always said, "Better is always the enemy of good enough", True but what the hell.
