New Eggleston Savoys ?

FWIW, the Savoy is going to require some real power. Think Pass X600.5. I think this will have 900 watts into 4 ohms.

As a contrasting opinion to Kurt, (whose opinion I think is typically very helpful), getting rid of the Nordost Valhallas was one of my best system upgrades.

I do think Lamm makes a good amp, and I even considered it. However, my speakers probably require a minimum of 300 watts into 4 ohms to properly control them with the music I like. I think yours would require even more.

Hey Rtn1,

WHAT?!!!
You disapprove of the Nordost Valhallas?!
Infidel!
(And, I take it quite personally that you don't approve of MY choice of speaker cables! Pistols at dawn, I say!)
;-)

I can understand somebody not liking the Valhallas. They can be a touch bright, and they are very detailed, to the point that if you already have a system that is detailed oriented, (i.e. perhaps using something like Wilson speakers), that they might seem a bit much. (Although my friend with the Rockport Antares is using them, and he used them when he was running the Avalon Eidolons too. Although, now that you brought it up, he did replace the Valhallas he used to use, as a preamp to amp interconnect, with the Jena Labs Pathfinders, which helped put some of the musicality back into his system.)

However, my Lamm M2.1 amplifiers, (unlike the aforementioned M2.2s), are just a bit rolled off on top, and going with the Valhallas improved the treble response, immensely, and really let the Andra II's Isotar tweeter do its thing!

My audio philosophy is: System synergy is everything!

I doubt the Lamm M2.2 would have enough power with only 220 watts. My room is too large. Pass Labs is on my list to hear. I had a friend tell me they were cold sounding so I don’t know. I think the Savoys only dip to 6 ohms so I am really looking at the 8 ohm power rating.
I will be experimenting over the next few months with cables. I will try some of the ones you guys are using and recommended.

Pass is certainly not known to make cold sounding amps unless he's changed direction. Smooth and beautiful tone come to mind, and not the last word in bass control, usually associated with full class A bias.
Note that this is only based on having a pair of Alephs at home a few years ago. There have been a few new products from him since.
Worth a try anyway, don't dismiss them.

Coxhaus, I am assuming that you bought new speakers?
If so, they will need many hours of playing before you can evaluate them.

I have a 25' X 17' room with Andra 2 speakers. I am using a Pass Labs X350.5 and it has plenty of power for the Andra's.
I would think the Pass X600.5 would be even better. The older Pass 350 and 600 were not as warm sounding as the new .5 series so maybe thats what your friend had.

Anyway, I agree they need power to sound there best, but they also need break in time.

By the way, I own Synergistic Reasearch cables and preferred them over the Valhalla's.

Make sure you pull the speakers out from the back wall, and sides they will need space to breathe.
