Well, I don't really considering this second consecutive entry to be "bumping" my immediately preceding question, because I'm essentially seeking new, different information now. My Sennheiser 650s arrived today, and I have been tempering a degree on initial disappointment (very high expectations along with an insatiable sense of excitement at acquiring all of this new equipment and capabilities) with the knowledge that they need to be broken in, just like my ATH-50Ms did, but the problem is my little Nuforce uDAC-2 doesn't drive the 650s nearly as well (in terms of simple amplitude) as it did the Audio Technicas. Looking at specs for the two headphones, that makes sense, even given my rusty knowledge of LCR circuits generally speaking, but my question is will the headphone amplifier section of the Maverick Audio D1 be able to drive the 650s just better than the tiny uDAC-2 HP, even though it may be far from ideal in the long run?
I just don't have enough gain for the 650s right now; the uDAC-2's volume pot is maxed out (never even came close to doing that with the ATH-M50s without making my ears bleed), and I'd like to turn it up more with the 650s, but can't. Looking at the specs for the D1 and the uDAC-2 and trying to correlate them with the Sennheiser 650 specs and my experience with the M50s is just too many calculations for me to perform. My D1 should be here in three more days according to Ryan, so I need to know whether I need to be thinking about having to buy an amplifier (like the A1) sooner than I'd like to or am really able to afford to, just so I can enjoy the 650s to a greater degree of their apparently awesome capabilities in the short term. So, will the D1 save my 650 bacon at least temporarily when it arrives? My wallet says "ouch" a lot easier than many other Head-Fi-ers, I'm afraid.
