Customer Feedback :

From Peter

I have now auditioned quite extensively, using a variety of familiar music, my new STR-1002.  I am very impressed by the improvement it brings to my 300B-based headphone amplifier. It is hard for me to quantify the percentage improvement, but the improvement I hear is all round and significant. 

The 1002 replaces the 5AR4 rectifier tube used in the circuit. I have been using my much treasured NOS Phillips / Miniwatt metal base 5AR4, and I really thought its performance couldn't be bettered. How wrong I was!  I have compared carefully, by switching the 5AR4 and STR-1002 back and forth. Your STR-1002 with 872A tubes is a complete revelation. The stunning midrange, thunderous bass and crystalline highs are all something to die for. There is so much detail and air in the music; every time I listen to a recording, I simply forget that I am listening to or through some gear, but rather listening to a live performance. I have never experienced anything better than this in headphone listening.
