Report Review for product Vacuum Tube - E34L, JJ Electronics

You are reporting the following product review:

Replaced the stock 6550’s in my Black Ice Audio 3502s Stereo Amp with the JJ E34L power tubes. Major improvement in sound stage and overall listening enjoyment. The 6550’s were way too bright and actually hurt my ears. The E34L is nice and mellow without a hint of harshness. Makes me want to keep on listening for hours and hours. Great choice and excellent customer service too.
