Hi to everybody! I'm selling the very well known and appreciated Metrum Acoustics Hex DAC! Five years old, it has the M2Tech USB module upgrade, the only scratch it has is on the front plate but looks like a crayon scratch - so visible only from the near distance, the rest is like new. At the interior, you will see only few solder points where the white ribbons wires are, because I have tested the Amorphous Core Lundahl LL1684 replacing the LL1588, just to compare the sound. I was surprised to find that the stock LL1588 sounded better that the LL1684 in this position...so it is not much to do for upgrading this DAC! You will be rewarded with a great sound and a very reliable product. The product is set now for the 220-240V Power Supply. If you will need the 100-120V Power I can fix it for you, just changing the strap wire ( in the last picture, left side) and doubling the fuse value. Just communicate with me and everything will be all right. Please ask for the shipping cost ( the package has almost 16 lb weight), it varies from Country to Country.. Just an example, for USA the shipping cost is $106 and for Germany is 57 euro.
