Pass Labs Amps - Does the heat bother you?

Friend

Congratulations on being able to have discretionary funds to make the purchase.  Since this question will have many responses - I will be brief:

Please add Convergent Audio Technology to your list.  If you can somehow make it to an audio show where they showcase their equipment - you can get a great feel for the sonics of their product.

My perspective may be on the warmer end of this spectrum - I have a set of Pass XS150s, ~450lbs of all Class A in a room that measures 27X36X9ft. These idle around 700W. In the winter they can add 5-6 degrees to the room after about 4-6 hours of listening. In the summer, the air conditioning more than compensates - and the impact is nil. 

I love the sound of Pass - especially Class A, and they have had some time to warm up. They sound even better after 2-3 glasses of amazing pinot, and even more so as the lights dim. 

Curious if anyone has any experience with the Coda s5.5 and if that thing is hot as well?  Would love to audition one to try vs my XA30.8

@jrareform, I've owned the X250.8 and XA30.8 and now own the Coda S5.5, and with my easy to drive speakers I don't find the Coda runs near as hot as either of those Pass amps.   I have a smallish 12x17 very well insulated room with no AC, and in the winter months either Pass amp would keep my room warm which was nice, but in the summer I would leave listening sessions in a sweat :(   Not so with Coda; I think the S5.5 is a killer sounding amp for the $$ if you can live with its very muscular 50w.

@ddafoe oh awesome.  What did you think of the pass Labs vs coda sound wise?  Been staring at the s5.5 for a while considering comparing the the xa30.8 but want to hear more opinions.  Thanks!

I find the S5.5 more like the X250.8 than the XA30.8 in terms of sound signature and also power, which is interesting.   I find the Coda much more resolving than the 30.8 which I found was less resolving than the X250.8; the 30.8 has some warmness and more rounded edges with a very meaty midrange.   I found the X250.8 more neutral compared to the 30.8 and allowed me to hear a little more into the recordings with slightly sharper resolving ability.  I thought the X250.8 was very refined but gave up little of that midrange magic and mass to its smaller class A brother.

I find the S5.5 a little more resolving then the X250.8 with a maybe a slightly drier sound while still offering a nice midrange and imaging.  The S5.5 high frequencies are likely the best of any amp I've owned.  They are very detailed but not in your face.    Considering its cost, size, and warranty, I really like it!
