I have the Matrix M-stage amp (Opa627 mod) with Sennheiser HD 650. Matrix M-stage is better or worse built in DA8?
I have a choice between Matrix X-Sabre with M-stage (opa627 mod) or Yulong DA8 with the integrated amp. Whether will be able built in in the DA8 amplifier well to work with earphones of 300 ohms, in comparison with Matrix M-stage? Excuse for my English.
I would say to go with the combo offer. High impedance headphones can sound off with the DA8 internal amp, but the M-stage is known to work well with the 650s. However, once you get into the 600 ohms headphones, something besides the DA8 integrated will serve you better as it loses a lot of control going above a normal volume level.
The DA8 integrated amp is no slouch with 32-300 ohm headphones though :)
