    perfect for the V1 of my 40-watt combo... beautiful warm & chimey cleans with great drive

    reviewed by: JP

    These tubes are well-made and sound good in terms of smoothness, and warmth which is a combination of harmonic warmth and midrange droop (imagine a frequency response graph shaped like a smile).

    The key here is application:

    1. You like less presence in the midrange during playback.
    2. You like a flat frequency response during playback, but your speakers/system combine to produce a midrange-forward frequency response (imagine a frequency response graph shaped like a frown).

    They didn’t sound bad, per se, in my system. But my system’s relatively flat frequence response revealed the midrange valley presented by this tube.

    Hope this helps someone with these particular goals.
