I use a couple Emotiva amps and, if you look at my systems, it's not because money is an object.
Granted...I use one of their big amps for just low frequency drivers on my Wisdom speakers and another Emotiva for just rear channels in my HT.
However, I've tried the XPA2 amp in other capacities and it's gives very strong performance on a super modest budget. If you try to pick this thing up, you quickly realize it's not your typical cheapo product. It has a big toroid transformer, good heat sinks, and speaker terminals/switches/connectors that compare well with virtually anything out there. Some parts could be improved internally, but you can say that about many amps charging $5k+
Their pre/processor is a bit clunky and "cheap" with the interface, but it actually sounds very nice, which is what I value most.
If you've got better speakers that are more resolving of differences in equipment than my Wisdoms or Maggies...plus a dedicated room with full treatments...and an active crossover/room correction like mine for even more refinement...more power to you.
Here's the problem with threads like these.
First, the original poster never mentions which Emotiva model he tried. Was it the same power rating?
He never mentions which preamp is feeding the amp. Parasound is a great value brand just like Emotiva, but I once made their JC1's sound terrible by driving them from a high quality Resolution Audio CDP that supposedly could go direct to amps. On other amps, it worked fine, but not the JC1s with the cables we were using. This is just one example of why these clowns who make categoric statements about brands without providing any details earn my "clown" title.
Next, he mentions using these amps on Sonus Faber Venere. I find it odd that someone would choose a solid state amp versus a tube amp for this speaker, but nevertheless, it is also very sensitive to setup and listening axis. Thus...just like the JC1s...I could easily make this speaker sound horrible with even $100k amplification.
Few people realize how much a speaker crossover impacts the sound from the amplifier. A tube amp can sound terrible on Speaker ABC which needs lots of current, but sound great on one that needs an amp to swing voltage.
Even without the drastic difference of tubes versus solid state, you can have large swings in performance within solid state and tube categories based strictly on the speaker.
For example, my McIntosh amp is rated at 250watts per channel. It will mate great with almost any speaker...especially because it has an autoformer. Thus, it has outperformed amps well above its price on many speakers.
Conversely, my modified Mccormack amps are among the best sounding (super transparent, liquid, and detailed) solid state amps I've heard...yet...they only do 125watts and can sound much less impressive when asked to drive certain demanding speakers full-range.
In short, be careful who you listen to and be wary of anyone making categoric statements with little experience or details.
Also, for the record, Benchmark, PSB, Emotiva, and Parasound are my recommendations for "best-bang-for-the-buck" brands.
