Thanks David for the answer.
I'm an owner of Benchamark DAC1 from more then 1 year. I'm really happy about it, but, you know, as an audiophile listener I'm always serching about something better, reasonable better I mean... also because in my experience differences of price don't mean "reasonable" differences of sound. I know very well about Weiss prices, but I have not occasion to hear it.
If you heard it, can you tell me about your opinion?
Thanks again...
