Got it. Much appreciated, pdrm360. Happy listening.

80% of the volume scale on the. dell. Thanks.

My source is a Dell XPS all in one. http://www.dell.com/us/p/xps-27-2720-aio/pd?oc=fdcwlp1397&model_id=xps-27-2720-aio No DAC in between. Still waiting ODAC to be delivered. Thank you, vlach.

Tried T1 with Fiio E9, loud enough; tried HD 700 with A1, loud enough. Now T1 with A1? Barely audible halfway through the volume knob. Already contacted Beyer USA. Thank you again, Perhapss.

Thanks, perhapss. I tied hd700 on A1, it's loud enough. I'm starting to get concerned. My T1 on A1 is anything but loud.

I use T1 with A1, which is a combo recommended by beyerdynamic itself. But I have to go as far as 3 quarters of the volume knob to get a decent volume. Is this normal? Am I missing anything? Many thanks.   BTW, there's no gain switch or whatsoever on the A1 unit.

Own 2 pairs of m4u 1, red and gray. Definitely my go to phones. Easiest to drive, straight from my 5S., they sound great no matter what kind of music I throw at them.

Thank you, Billy. That really helps. I ordered T1 along with A1. My setup would look like: PC-->Audioengine D1 (as DAC only)-->Beyer A1-->T1. Is this ok to drive T1 properly? Pretty new to audiophile world. Thanks again for your kind help.

bump. really hope someone can help me with this concern. Thanks, again.

Quick question: it seems audioengine d1 is an entry-level amp/dac combo. Can I just hook it up to my eyerdynamic a1 as dac only? Many thanks.

Thanks, Kragen. Already got Fiio E11 and E17. E11 works great, though there's only minimal improvement in sound quality with Denon D600 amped up. E17 still in box. Been busy with burning in the phones with an online burn-in player.   Any thoughts on the upcoming beyerdynamic a 200 p? Looks...

Thanks, Kragen. Already got Fiio E11 and E17. E7 works great, though for Denon D600, there's very minimal improvement in sound quality. Haven't even unpacked the E17 which seems to require a bit of learning involved. Been so busy with using http://www.tekfusiontechnologies.com/Burner/Burner.php...

Following Eric's advice, here comes the revised list of the sets I'm gonna keep for now:   Audiophile Headphones:   --Open back: * AKG Q 701 * Beyerdynamic DT 990 Premium 32 ohm (burning-in, wanna give them a chance to prove themselves. Anyhow, they were                                    ...

Yes, Eric. Pretty much my "Go-to pairs" (Audio-Technica ATH-M50 and Sennheiser HD25SP II) ought to be "gone-too pairs". Lol. Having lost the original packaging, I wonder if i can successfully return them for a refund, though they r in mint condition, considering I have way too many pairs to...
