I had the pleasure of dealing with Jack at the Audiobarn earlier this year. I'd just returned from living abroad in the United States and was seeking to trade a very high-end piece that had become surplus to requirements. We rapidly came to a deal and within a short time, I was the proud owner of a Mola-Mola Tambaqui DAC which has now taken pride of place in my home theater system. The whole process was very simple, Audiobarn took care of all the shipping arrangements and when the Tambaqui was delivered, Jack took the time to thank me for the purchase and make sure that everything was as it should be. High-end Audio is well-served by dealers in the United States but it's rare to find a dealer here in the UK of the calibre of Audiobarn. I have no hesitation at all in recommending them. If you are serious about your HiFi then Audiobarn should be your first stop on your personal path to audio Nirvana
