Hi - I'm currently evaluating a Benchmark HPA4 headphone amp. I like a lot. A LOT. I'm driving it via a Benchmark DAC3 HGC, and it sits in front of a Benchmark AHB2 power amp. Senn HD800S HPs complete that picture. But the HPA4 costs a LOT - $3K (at least that's a lot for me). That part I don't like. But the HPA4 has some pretty impressive performance numbers, and it delivers some amazing sound. I would love to hear some suggestions for higher-end headphone amp alternatives that you think I should be considering in the "up to $3K" price range - alternatives that you think would offer comparable performance/value compared to the HPA4. I don't need a DAC in the HP amp. Balanced audio inputs/outputs are required, and I'd prefer a balanced headphone output as well. Remote control is a definite want as well. Not looking for tube amp solutions - I want to keep the audio chain as uncolored and clean as possible all the way to the AHB2 and speakers. Thanks for your thoughts!
