I have a feeling that the Micro Amp struggles powering the HD 650s (even through the MicroDAC). At higher volumes, it just doesn't as smooth as I would expect it to. Is this just the sonic signature of the headroom amps, or is it a wee bit underpowered, or is it a problem with the power...

I've got the Micro Stack. Just wondering if HeadRoom Micro Amps are a good match for Grado 225i? Or will they end up being way too bright? I currently run the stack with Sennheiser 650s and Denon 5000s. They're fine with the denons, but I feel they don't have enough power for the Sennheiser...

I've got the following headphones: Sennheiser 650, 448 Denon 5000, 1001 Grado 228   I also happen to have the headroom Micro Amp and Dac.   I'm looking for a setup for the office and one for home. I'll be keeping the sennheiser 650 at home. Everything else is up for grabs.  ...

Any recommendations on a good source for the burson HA-160. I'm thinking of the following options: a) Get the HA-160D instead of the HA-160. b) Get the Arcam rDac. c) Cambridge Magic (or something like that).   Any opinions?   It'll be the same money for the most part. I expect DAC...

Just wondering what Woo Audio amp would be in the same category as the Little Dot MK IV ($350). The WooAudio 3 ($500) or the WooAudio 6 ($600)?

I'll be running Denon 5000s and Sennheiser 650s with the amp. Any recommendations between these two amps? Any other amps I should consider that are better value (same quality, cheaper price?).

I'm currently running the HeadRoom Micro Amp/Dac stack with Sennheiser 650s and Denon 5000s.   Any recommendations on what I could upgrade? (Amp? Dac? Headphones?).  What I should try out that would be a substantial upgrade and not a sidways move?

Any recommendations? I also own the headroom Micro Stack (Dac + Amp). Might consider selling that stack if someone can suggest a headphone Amp to go with the Arcam rDac.
