Report Review for product Vacuum Tube - 12AX7 / ECC83, JJ Electronics

The JJ ECC83s is the stock 12AX7-type preamp tube in my Vincent Audio SV-500 integrated stereo amplifier. I had previously rolled all sorts of NOS tubes, Mullard, RFT, Tung-Sol, etc. but turns out the JJ ECC83s sounds best in the SV-500. Nice sounding tube, warm with good sound stage, low noise.
