I had a Pass x350 for fifteen years and it never got more than warm to the touch.
Heat from amps?
Looking through the forum threads on amplifiers I’ve read posts stating how the Pass Labs x250.8 gets warm enough for the occupants in the room to take notice, along with comments of being thankful for having an air conditioned room. In degrees, how much are we talking about at what levels of volume? I’d like to take all things into consideration while comparing power amplifiers. I have not been playing my Bryston 4B3 demo at loud volumes for long periods of time, but, as of yet, and the heat sinks have only gotten warm to the touch.
update : Keith English at Pass Labs had me call the dealer who I,ports Harbeth. "The 250.8 is too powerful, the XA25.8 is what we recommend." When asked about the XA30.8 I was told there is little difference compared to the XA25.8," and they reiterated the recommendation of the XA25.8 which has more than capable for handling my Harbeth 30.2 XDs. I thought dealers like to up sell? I'm worried about the handling of the bass on the XA25.8.

Pass 250.8 does get warm, no doubt, but I would never call it HOT...to me, hot means you couldnt touch it without burning yourself....incandescent lightbulbs get hot....both of these items indeed radiate heat, own them all, but have never found they make a room "uncomfortable", and I live in Florida....owning the 250.8, I have never seen it leave Class A, per the meter, even at loud levels...my speakers are rated @ 90 db efficiency....I imagine the idle temp and "max" temperature of the unit are pretty much identical, as that is the design of the bias and heatsinks.... |
Jim Bob the coda gear sounds better then the pass gear which tends to sound a little too warm The coda amps sound warm but are a touch more neutral then Pass Labs amps The coda is configurable so you can choose yrour total power and amount of class a power that you need Also thecoda amps run warm but don’t heat up the room At any time you can send the amp in to coda and they can re bias the amp The reviewer Terry London found the 6k coda .8 poweramp came shockingly close to a 14k pair of pass mono amps https://hometheaterreview.com/coda-technologies-continuum-no-8-stereo-amplifier/ Dave and troy Audio intellect nj CODA DEALERS |
