My current headphone inventory consists of HE-400, HD600, T50RP Mad Dogs, D5000, Pro 900, AD900, HM5, and HFI-780. I would like a solid state amp. I am considering the Schiit Asgard, Matrix M-Stage, O2/ODA, and other recommendations that you might have. I would like to keep the budget under $350.
The DAC is more questionable because the ODAC might be perfectly fine for entry level desktop amps such as the ones I have mentioned. I know its measured to be transparent, which is what I'm after, but if something such as the Schiit Bifrost, Cambridge Audio DAC Magic, or HRT Music Streamer II or II+ is worth it for this type of amp, then I would certainly consider the upgrade. Obviously open to other recommendations as well. I would like to keep this under $300 but can stretch if needed.
Just curious what you all think would be best for the budget, either ones I listed or others you know of that are better. Thank you very much.
