have you ever bought stereo without listening first

I don't think David Belles ever designed a bad component, and he's been working on the Virtuoso for years (it was originally supposed to have rolled out 2 or 3 years ago), so I can't imagine how you could be disappointed.  Because of the delay, there are very few still actually in customers' hands, and hence virtually no third-party feedback.  Keep us posted!

I will post a review once I get it. I am pretty convinced it will match well with my speakers. One piece of news that concerns me is that David Belles is retiring.The Virtuoso line is considered his best work.  I wonder how is this going to affect parts and service?

I'm a bad example...except my first two bookshelf speakers I got at circuit city in my twenties, everything I've bought since has never been auditioned. But I tend to research the heck out of everything. I learned early on not to worry about specs. 
  

Like sandthemall I didn’t listen to the amp, pre-amp, speakers or turntable before I bought them the past few months.  I relied upon reviews and the comments of people that had purchased the items and heard them in their homes.  When the reviews and comments pretty much agreed that the sound and functioning were pleasing, at that point I made the purchase.

i’m a bit different at this forum because I wasn’t looking to spend very much to get the ultimate sound.  I’m sure that spending thousands more on equipment would bring better sound, but I am satisfied with what I bought after listening to a very pedestrian system for 30 years.  Also, unless I was willing to put considerable money into the source music (e.g., purchasing $50-$100 enhanced def records to play on my $2,000 TT), buying more expensive equipment wouldn’t make as much sense for me.  Not saying that this is how it should be done, but when you know ahead of time the amount you are willing to spend, then that informs your buying choices.  Enjoy your new equipment — it sounds very nice.

@lobinero - If you are making a major purchase from someone on the verge of retirement. Definitely ask if he is selling the business to anyone (who will support his legacy equipment). If he isn't, ask for schematics and parts list so you can provide to any technician who may work on your stuff in the future. Why would he say "no"?
