I recently bought Audiobarn's exdem Naim NAP500DR power amp, together with some new SuperLumina cabling and some Fraim levels/legs. As this purchase made some of my equipment redundant, I asked Audiobarn for a part exchange deal (involving my NAP250DR, some SuperLumina cables and a PowerLine). Jack was extremely patient during the negotiations and equipment ordering and was more than fair with the trade-in deal. Now that the NAP500DR and new cabling have settled in, I am delighted with the superb uplift in sound quality. Combine this with great advice, patience and a good deal I have experienced with Audiobarn, I am absolutely delighted. I would not hesitate to recommend Audiobarn and, I am sure, will be dealing with them again in the future. Keep up the great service!
