I prefer the 701's to the 650's on all of the above units.

"ZD"= Zana Deux. Not balanced, but sounds more real to me the the Balanced Headroom units.

Just had a few minutes to listen to an hour warmed up ZD hooked up to my only available source, iRiver H340 with high bit rate mp3s. Even these sound really nice. Can't wait to try it with my MacBkP apple lossless>Cosecant>ZD>701's or S650's.

Just got my ZD. Looks great!! Have the tubes in. Any special 1st time start up procedures? Thanks

I'd also like to "hear" the best 701 tube, and a source for tubes. Thanks.(awaiting the ZD ready for shipment)

Mine is ready for sipment!!!!!

Does the iaudio7 play WMA LOSSLESS?

So what do you think a still sealed in the cleaer plastic wrap box H140 is worth? Found one.

So, which is the better sounding unit? Or do they have the same sound with different features? Thanks

Have any of you actually tried the 701 balanced yet? Results as good as claimed?

Waiting on a Zana. Using a Headroom DT Maxed with pretty good results. What do expect the differnce with the Zana will be?

Cost is the big difference in the above approaches. Even a Headroom BitHead maybe a cost effective and convenient external USB Dac/amp.

Two very different SQ approaches: have you tried simple line out to the amp? The digital out to an external DAC will most likely give better SQ. Optical out likely better than USB. However, USB external DACs can be EXTREMELY FABULOUS. I love my MacBK PRo iTunes ALL> USB Wavelength Cosecant > amp...

In my experience Macbook Pro>itunes ALL>USB >DT Maxed +Max Dac>701or 650=very very nice. (Better than WinXP WMA LL via Jriver/ASIO), BUT, add in the Wavelength Cosecant USB DAC and its now FABULOUS!! I'm now wondering how much better a Balanced Home Maxed out would add to these combinations.

Anyone have experience with HR Balanced Home with Max modules and Dac? I am currently using HRDTMaxed with Dac. This sounds very good being fed iTunes ALL from Macbook Pro via USB, BUT truely much finer sound is had when I go MBPro>USB>Wavelength Cosecant>HRDTMAX>701's. I wondering how much...
