I agree with Elizabeth and lalitk, but having said that, I would be cautious about dealing with them too. I had an issue of a different nature that led me to distrust them and question their attitude towards their customers.
USA Tube Audio
Paul at USA tube audio charge my credit card after I returned a Ayon power amp to him. He gave me a complete refund for the amp.It was return with in the two week test period. He sent me an email that stated I have to paid a fee for the 0% financing. The fee was for 471.15. He did not charge this fee until 3 weeks after the amp was returned, he sent me an email. This was a unauthorize charge to my card. I am fighting this charge now. This is how he rewards customer's who brought items from him is the pass if things do not go his way. Be careful when you deal with this company, you might end up with a surprise.
