    One thing to note, the fans are very so slightly audible between tracks from my sitting position but it certainly isn't even close to the noise I've I've heard from buzzing Transformers on other kit.

    The powerline adapters are no longer making noise through my speakers either.

    So far so good.

    Not unless you want to take everything off the top of them. It could be done with some patience mind you.

    struth you could stick a resistor in line with the fans to slow them down

    Mine are pro Amps and have fans as the cases have no holes and were designed to sit in jukeboxes so fan noise wasn't a consideration. As I don't have mine on for long much I dare say I could cut the power cable. Even when left on they don't get warm

    I love the fan cooling. Liquid cooled? That's where the money is

    yes liquid nitrogen and CLC filters where the C is made whit ultra capacitors, The new Graphene Ones and the L is superconducting tube serves to carry the Nitrogen around
    of course one will have to use CVD diamond in place of the Kerafool WTF may as well get the sinks in CVD diamond deposited over the superconducting tube inductors

    I am working on it

    Well maybe in 10 years time …
    By then they should have found a way to negatively dope the CVD diamond , only positive doping had same results so far
    In the mean time Silicon carbide transistors are at the top of my shopping list
