Power Amp To Go With Cary SLP98P Preamp

A further thought regarding the XA30.8: Given the small size of your present room, depending on how well it is air-conditioned the heat that would be introduced by the 400 watt AC power consumption of the XA30.8 may be an issue. The XA25 I use may be preferable in that regard, as its specified power consumption is only 240 watts, while according to Stereophile’s measurements it can nevertheless supply 80 and 130 watts into 8 and 4 ohms respectively.

Your PrimaLuna amp has a specified power consumption of 232 watts, but I believe it is biased to operate in class AB, while the two Pass amps operate in class A aside from occasional instances when high volume dynamic peaks in the music may cause them to transition to AB. Consequently your PrimaLuna amp is probably consuming significantly less than 232 watts most of the time, depending on the dynamics of the music, while the two Pass amps consume essentially the same amount of power (400 watts and 240 watts, respectively) most of the time.  And the amount of heat introduced into the room will be proportional to those power consumption numbers.

Good luck. Regards,

Thanks for taking all the time Al to help me. That was my concern with the Cary tube amp and the Pass Labs amp and why are was considering the solid state Cary amp. The room is small and in the summer it gets pretty hot in Oklahoma. The smaller Pass amp is a good call. Thank you!

The little XA25 amp is pretty sweet too.  A few buddies with Cary tube amps also have the XA25 and flip back and forth for variety.  If your Ryan speakers are truly 85db, something else to consider about efficiency - depending how loud you turn it up for in-room our outside-of-room listening.   In a small room, and lower listening levels it might be okay. I can say the SA-200.2 I had before did not run that warm and does run in  Class A mode in lower wattage.  I don't recall the limits. Plan on buying some better copper interconnect cables with these SS amps IF you like a softer sound, particularly if you are running brighter tubes in your SLP-98 preamp.  

I talked to Mark at Reno Hi Fi this afternoon and he recommended the 150.8 Power amp so I am researching a little about it. Class AB so it won’t get so hot in my small room and gives me more watts for my more inefficient speakers. A really nice conversation and very informative. It should mate well with my Cary Preamp.

dylanfan,
have you heard your Ryan 630 speakers with any other amp than a Cary CAD 120S?
