Integrated Amp for Focal 1027be speakers

I was just about to post essentially the same comment that Bryon just posted. I would also highlight the following statement in the same measurements discussion of the XA30.5:

The amplifier doesn't actually clip (defined as the THD reaching 1%) until a much higher power level: 130Wpc into 8 ohms (21.14dBW). Even higher powers were available into lower impedances before clipping: 195Wpc into 4 ohms with both channels driven (19.9dBW), and 332W into 2 ohms with one channel driven (19.2dBW).

The Pass site indicates that the INT-30A is "based on the XA30.5," and the specs that are presented for it are essentially the same as those of the XA30.5. The only thing that gives me pause is that the INT-30A weighs 2 pounds less than the XA30.5, even though it includes additional functions.

Communicating with Pass would seem to be worthwhile, as Bryon suggested.

Lloyd's comment is correct. The information at the Pass site quantifies it nicely. The INT-30A consumes 200 watts as long as it is operating Class A, which will be most of the time. So it will put about as much heat into the room as two 100 watt light bulbs. Also, the manual for the INT-30A indicates that its heatsinks can be expected to be at a temperature of 25 to 30 degrees C above the ambient temperature, which probably means around 125 degrees F. Not too bad, as Class A amps go.

Also, assuming that the impedance curve for the 1027Be is similar to that of the 1037Be, and would therefore be in the vicinity of 4 to 6 ohms through most of the bass and mid-bass regions (where the greatest amount of musical energy generally occurs), the INT-30A would not leave Class A until something closer to 60 watts is required, rather than 30 watts.
