Dear Songmic,   I wonder when did you order your Airmotiv 4 as their website did not show any more 10% promotion discount. I am on the fence now, but the 10% discount would make me jump the fence. How do you like the Airmotive4 sound compare to the ones you had.   Thanks for sharing your...

I think NAD might overestimate dealer service in their international network. Is NAD policy allowing dealer to charge consumer for every firmware upgrades? It should be made clear as it could be out of control. I for one will not buy it until it is clearly stated. About to pull the trigger until...

I wonder if the op amps you chose move the sound stage to the front rather than the back of the speakers like mcullinan mentioned. Thanks for sharing.

Echohifi, is your minimax has socketed op amp? Or you have to desolder the solder the new opamp in? I look at EE website and they no longer has the normal Dac but only the Dac plus version that has tube output stage. Do you have the chance to audition one?

I am trying to get completely into computer audio, so a Dac with digital volume control would be my target. Use it to connect to the mono blocks. As home auditioning is next to impossible, so I rely a lot on those with direct expericence to guide me. I try to get the Dac that I could live with...

I have been following this thread and hoping that those who has both M51 and Wyred 4 Sound DAC2 could share their experiences comparing the two. Thanks.

Has anyone try remove the Power Supply module from the unit? I would like to know if the input voltage could be changed from 220V <--> 110 V by just soldering and de-soldering some wires or not. Would appreciate the picture of underside of the power supply module. I plan to buy one unit to be...

I plan to buy the V8P for my daughter. But we live in Thailand (220v) and she will be using it half of the year in USA (110v). Can you please advise if the included power supply is universal 100-240V or a dedicated 110V for US? Thanks.

How can I obtain Lawrence e-mail so I could confirm what are in the price asked? I saw some of the thread talks about USB-coax adapter is included, but I could not see it on the eBay ads by biglawhk (I presume he is Lawrence)

Which opamp he put in the Pig? What is the supply regualtion and if there's any cross feed circuit?

Andrea, Thanks for the input. On paper, my preference is in favor of the XM3, but the xfeed function is the one I will rely on the most as the normal headphone amp with absolute channel separation is too much for me for continuous listening. Will await your report with keen interest.

Living in Bangkok, the money back guarantee does not do me any good. That's why I follow this thred with keen interest. Do not have a chance to try out any amp. Those that attracts my attention are Total Bithead, XM3, and Xin Mini. Your input is highly appreciated. I would very much interest to...
