Luxman DA-06 Dac...anyone?

Price apparently has been reduced to $5,000. Given the importance of the power supply in high end equipment, in general, and in DACs, in particular, I would definitely expect a step down transformer to degrade sound quality.

Very positive reviews have been published in AudioStream and The Computer Audiophile.

I've heard Luxman had some issues with the DA-06's USB interface (relay noise) have they fixed this? reviewers don't say anything about it.

The relay "noise" you refer to is merely an audible "click" that can be heard when the DAC changes formats. There is no click between tracks of the same album or between albums of the same format, at least with playback via J River Media Center. One reviewer, in response to a question, commented that he heard it but it didn't bother him.

I can confirm that the list price is $6K not $5k. Also, the click is also present with their D-06 cdp using the digital inputs. Finally, I am really on the fence about getting a 100V Japenese spec version and using a step down transformer. Assuming the transformer is of good quality, why would using one degrade the sound? The DA-06 doenst care if the power came from the wall or a transformer right?

Some US dealers continue to list the DA-06 at $6,000, e.g. Music Direct, while others list it at $5,000, e.g. TTVJ. I was told about the price reduction by a Luxman dealer in Canada.

Tboooe, it seems like you are trying really hard to convince yourself that a step down transformer is not going to affect the sound, judging from the fact that you are asking for agreement rather than opinions.
