Probably is since no one else has commented.  But I have to raise a Spockian eyebrow at a giving a Very High Recommendation to a component whose volume control gets so hot it uncomfortable to touch after only an hour of use.  It shouldn't get that hot after any amount of use.  Surely that has to raise some doubt as to the basic usability of the thing; I mean we are talking about the volume control not a heat sink or the back cover.  This is a $6K amp - my $400 Fatman amp doesn't overheat like that.  Taking it a step further, doesn't it suggest a design flaw if heat is being dissipated through a user control?  If the volume control is that hot, how much heat is the rest of it giving off?

Nope. You could get a quieter, higher powered, and arguably better sounding garden variety Onkyo amp for $400 - $500 - less than one tenth the cost of this turd. And in the extremely unlikely chance that your volume control got slightly warm to the touch after several hours of operation, your local Onkyo dealer would gladly exchange it for one that didn't have that problem. 

This amp, and the magazine that's "reviewing" it is a joke. Seriously, a $6,000 amp that has FM-like noise levels, no balanced inputs, and can barely deliver 60 watts without distorting heavily? 

And of course, Stereophile's resident advertising agents/manufacturer spokespersons chime in with the usual BS and blather:

"I was especially impressed by the EHF-100's overall musicality—a word I mean literally, not as a coded term for a particular sort of tonal balance: Not only did the EHF-100 sound good, it did a better-than-average job of playing music. Lines of notes had very good momentum and flow, suffering none of the temporal distortions of lesser gear (of any price)"... -Dudley

 

At least he didn't say "it had good pace and rhythm"...

 

"Overall, the EHF-100 measures well for a classic design using a pair of KT88s as output tubes for each channel." - Atkinson

Yeah, it's a horse drawn carriage and while it might not be a 2011 Mercedes V-12, it measures well for a horse drawn carriage. "Very highly recommended"...blah...blah...blah...
