Richard, I agree with mcgsxr regarding quality. I may be the source of some of the things you read. I bought two of the JVCs and returned each before finally getting a keeper. My problem may have been where I bought them, an eBay retailer here in Southern Cal. They seem to buy up a lot of returns and resell them. When I brought back the first one they did not even bother to learn what was wrong, instead they just checked to see that everything was there and put it back in stock! My third, (bought from a different source) has been a trooper. It does have a tube like sound to my ears, but it iws not quite there. I love it for its price and for how convenient it is, but I will likely end up going back to tubes.
One question, I thought you have found sonic nirvana in the form of a Clari-T? Does it have a chink in its armor? Some reason to go back to the JVC?
