Ayre QB-9 USB DAC

Feel the same way as Horacio. I'm usually open minded about audio components, but when year old thread is resurrected just to promote a competing product by small number of people that cross post to several different threads, it makes me wonder. I did look at the web site for Tranquility DAC. There is very little technical information about the DAC there, other than the use of non-oversampling DAC. There are a dozen different NOS DAC sold on eBay for less than $500. It's not clear to me how this one is different from the rest of the pack, other than the use of $30 extruded aluminum case from Hammond Manufacturing. I would love to hear from someone who compared Tranquility against another NOS DAC, but perhaps in a different thread.

My comments are not directed at specific member. Rather I was commenting on the "situation" in this thread. Personally I would care less if Tranquility is the best thing since sliced bread or not. Some prefer NOS DAC. Some prefer Sony PS1. Some prefer Bose sound. To each his own.

What I was trying to point out was the manner the comparison was presented. As I see it two cardinal audiophile rules were violated.

1. giving an unsolicited advice.
2. comparing product you own against product you haven't heard.

No, there are no such written rules and I'm only half serious. I cringe every time someone does that. For example,

user1: "I just bought a CD player XYZ and it's great!. Has anyone heard this before?"
user2: "Player XYZ sucks compared to ABC that I own."

user1: "Has anyone compared amp AAA and BBB?"
user2: "I own AAA and it's better than BBB"
user1: "Have you auditioned BBB?"
user2: "No"
