The headphone amplifier of this is great!
It's real fun to listen to music now with headphones.
It looks absolutely stunning is wonderful.
This is quality!
headphone amplifier is gold! Where an edited upgrade with this as an amplifier!
Can not give it more than 10 out of 10 for the incredible sound and functionality for the price. DAC, headphone amplifier and preamp that everyone plays in a really high league.
Was bought primarily as a replacement for my Cambridge DacMagic http://www.prisjakt.nu/produkt.php?o=372708 and the result was bigger difference than I could believe.
Dacmagicen cost the new 2700 - and right when it came praised the DAC for its price but only DAC part in HD-DAC1 is easily worth it 3 times higher price.
Have only used it for 2 days now but it struck me directly right of the large difference in detail in the treble, midrange and control in the base. It still Marantz character in tone as little about it warmer and fuller way. So to me that is sensitive to light / cutting / crisp treble, this is as close as I can get high definition audio that is still pleasant to listen to (with the peripherals I have).
The first I tested huh running Squeezebox to HD DAC1 and to my Mid surround amplifier Marantz SR5004.
This gave a really big lift greater than switching to my amplifier NAD M3.
The right to my Marantz SR5004 lifted from performing 50% of the NAD M3 sound quality to 90%.
So if you buy a surround amplifier in the SR5004 class (7000 :-) + HD DAC1 (8000 :-) for a total of 15000: - you can get 90% of the sound quality to the if you buy a 2 channel amplifier in the NAD M3 class (around 20000 :-) + HD DAC1 (8000 :-) for a total of 28000: -. The biggest difference huh pressure and check the base of my floor-standing speaker but with stand why huh difference is even smaller.
The following setup I have had time to test HD DAC1 with so far.
B & W 703
Nad M3 (M3 running only as the final step and HD DAC1 as preamp + DAC)
Marantz SR5004 (Run HD DAC1 to DAC only)
Squeezebox Touch SPDIF / Coax only slush for better sound quality
Windows computer (USB DAC)
Will test the following forward too.
XTZ 93.23 / 21 Speaker
XTZ sub W8.16
XTZ sub W12.16
Newer Marantz amplifier
PS Drive Marantz HD DAC1 with upgraded power cable then this will make a tangible difference and have not tested with the original.
