I have had a Telwire power cord for a month or so now and it sounds wonderful on my refurbished Pilot EL84, 17 watt tube integrated amp. It bested a couple of other well-known brand cords. The cord, on initial listen, sounds better than most cords when new. However, after about 150 hours, the highs and lows become fully extended and the midranges really start to fully flesh out. This is a very muscial cord when matched to the right component. This cord is as close to neutral as any cord that I've ever listened to, with very little of a "house" sound. It is very well built and because of its unique construction, it is very flexible and easy to fit on most components without having to wrestle it behind the cabinet. The connectors are the excellent Oyaide P004 and C004, in my opinion, the best Oyaide models with the least sonic signature. The current introductory price of $399.00 for the Telwire cord is a good bargain and the maker offers a 30-day return policy.
