    I respectfully disagree. Low wattage SET, 99 dB Daedalus in a larger than 40 x 30 x 27 foot room. No issues and certainly no distortion.

    Tungsol KT 170 just landed

    In conversation with KS, my understanding to attain the best benefits the KT170 offers, some circuit and chassis redesign was needed. Larger power transformer, larger chassis with thicker metal and other implementation to reduce vibration. Their new integrated T-2000 30th Anniversary KT170...

    " There are no speakers; there are no walls." - A brief summary of Allnic's current Line Stage (preamplifier) product line.

    After some time with the Allnic L-9000 and tube rolling any variant I could source, the NOS tubes supplied by KS Park hit all the marks well for the overall best presentation. This was a journey I do not regret. Alternatively, I found the 300B of the L-10,000 had much less influence than the...

    SET amp owners thread

    I was saddened to hear about the discontinuation of the Allnic A-311 low wattage series, the amps with which I am most personally smitten. I found better resolution and a dead silent circuit by in part omitting the parallel circuit design. 60W to 7.5W in my personal system missed nothing...
