Hi, I have been reading a lot about Sennheiser HD 700. Apparently, they are OK to be driven from a portable (not very powerful device), but for best results one should use a DAC/amp.
Now, I found a reasonably priced DAC/amp: Musical Fidelity V90-HPA. Here's my problem though: The frequency of the headphones is 8hz-44khz. The frequency of the aforementioned DAC/amp is 20hz-20khz. In other words, the headphones have a wider frequency range than the amp.
Does that mean the DAC/amp is not good enough for the headphones? Would I be losing some quality? Thanks for any hints. (Apologies if this question has been asked before; I couldn't find anything related.)
