I have commented on HP4 elsewhere on head-fi. Just search on my username.
I have extensively listened to the EAR HP4 and compared them to other very high end amps. In short I can inform you that casual comparisons at Hi-fi shops won't reveal anything on the sonic qualities of this amp.
For me it all started to make sense after very extensive listening with music that I am intimately familiar with.
I can summarize my findings into one phrase: without equal
It produces sound that is very difficult to explain:
+ it is highly dynamic, yet utterly subtle.
+ it is hyper detailed, yet extremely effortless.
+ it is equal or better than Sennheiser Orpheus in low level detail retrieval, yet produces additional body and dimension, lacking on the Orpheus.
+ it has a three dimensional, expansive, airy soundstage, yet it is hyper-exact in positioning instruments in that soundstage.
+ its bass response is fine (although not world class) with good continuity with the rest of the spectrum.
+ It is a magical, ALL TRIODE, T-coupled design, no hybrid solutions here.
- it is ridiculously expensive.
- it features a very strange circuit design. I have talked to a few people who have done some simulations on it, and they all have informed me that it performs sooo **** it makes BAD look good.
Based on what I have heard on its electricaI performance I can't really make any recommendations or condemnations. I believe that an amp SO EXPENSIVE should also perform fairly ok (within reasonable limits) on the test bench. It seems the HP4 cannot, I don't know, I haven't seen any measurements myself.
Its sonic ability is so beyond anything on the marked ..... I am really without words ...
