I have Magnepan 3.6's driven by an Ampzilla 2000 (200 wpc @4 ohms) in a 16 x 8 x 24' room and have more than enough power.
The Pass lab power amps work great with Magnepans. The Xa60.5 is very expensive, perhaps you should also look at the X150.5.
I do not think heat will be a big problem if you do not listen continuously all day. I turn off the air to reduce noise when I listen.
I own a Pass Lab Xono, X1 for pre-amplification and they are hard to beat. Nelson Pass has designed many of the Magnepan xovers and knows Magnepans very well.
I haven't heard both amps, but I've used the Cary 500 MBs for a couple of years with my 1.6QRs. The Carys run cool. They don't put out nearly as much heat as my McCormack DNA 1 monoblocks did. I would describe the Cary/Maggie midrange as heavenly. I just love those amps and I expect to keep them until death do us part! For me, they are the "stop looking" answer. Before I bought the Cary's I also had a strong interest in the Pass amps. I decided to go with the Cary's and have never had a moment of regret. I don't doubt the Pass amps are also a good match. They good thing is that resale of either is no problem, so experimentation is not that painful.
Thanks guys. Appreciate the input. Yes, the Pass XA60.5's are expensive, so I'll need to find a good deal on a used pair. I'd prefer to go with monoblocks, and love Class A, thus my preference over the X150.5.
The Cary's seem to be hard to find, so that's the downside there. However, I think I may just wait for a pair to come up on Agon, unless a really good deal on a pair of XA60.5's presents itself.
I do love my Cary's, but....I think Pass Labs makes about the best sounding amps there are period. With almost any speaker.
That said, for the 1.7's I would look at the new Sanders Sound (or an Innersound ESL 300 if you can find one). I had an Innersound ESL with my first pair of Maggies (1.6's), and then used it with a set of 3.6R's and that is one great amp.
There is a great synergy with the Sanders/Innersound amps and Maggies. I would try that before I ponied up for the Cary or Pass. But, you can't go wrong with any of those great amps.
Congrats and enjoy.
I think that is a sound approach (no pun intended). I spent a good long while deciding on the Cary's, then waited another good long while for a pair to show up on Agon. In the end, we listen to a whole system, so Cary/Maggie may be better for one source/preamp/room/listener preference situation and Pass/Maggie may be better for another. When I bought the Cary's, I expected to rotate through a few other options before I reached Valhalla. If you find a good buy on the Pass, go for it. If the Cary's come up, that's great. You can resell either without any issues if you want to continue exploring.
This 1.7 review
made me interested in the XA100.5 monos for my 3.6´s
Hasse - thanks for the link. How do you get to read stuff? Do you have to buy the print magazine, sign up fo ronline subscription, pay to read, what? If you do sign up or somehow get to read the articles online, do you get lots of emails / spam from them and their sponsors? I guess I've become an out-of-touch old fart who doesn't understand the new way of doing stuff. Thanks again for any info.
Honest1 - just click on one of the links next to the cover image at the top of the page to download either the standard or high resolution versions. The standard version is fine to read the review, while the high res version provides much better images but in a significantly larger download.
Hasse - Thanks for the link. I also read this review and that's what got me interested in Pass. Did you actually buy a pair of XA100.5's?
Kenl - no, but they are on my shortlist of amps.
The best amps for you are the TRL Samson monoblock amps. They are amazing and run cool.
They never show up used, but I see a set for sale now. You will not find better sound and based on your comments are exactly what you want.
The XA-60.5 are exceptional amplifiers. They will be sufficient for your room and listening volume, but they will not provide much room to grow if you shift the system to a larger room and start listening at louder volumes. That said, if you don't see this happening, then the XA-60.5 amps would be an excellent choice provided they create a sound you enjoy versus the other alternatives.
A bonus is their strong resale value, particularly if they are purchased used.
Both are great amps
I would say the Pass would match best with the Pass solid state Pre amps and The Cary would run its best with a tube pre amp.
In any regard check out this awesome Pass Labs/ Magnepan video and how its owner of this Magnepan 1.7 /Pass Labs system is in a blissful state of mind.
Thanks everyone. Earlier today I purchased the pair of Pass XA60.5's that have been listed here on Agon. The seller made me a very good deal, and I'm picking them up on Wednesday. I'm really looking forward to hearing them in my system. I just wish I had a room like that in the video. Cool set-up.
