    Doesn't high-end amp sellers place their tube amps on elevated granite stands?
    Most people just listen to music and watch movies. I EXPERIENCE them.

    I built them but I have know idea what they are capable of? You have never been in the room with them, never heard them, and are going to tell me that I am wrong or missing something?

    Excuse me while I have a good laugh....

    Your arrogance is absurd John. Forgive me for trying to actually elevate your experience. Keep thinking you know it all. I don’t have to hear your amps to know there is massive potential being left on the table.

    Granite is very ring-y.
    It's consequently a lousy turntable plinth material.
    How that would translate to an amplifier is unknown to me; certainly could be a problem with any tubes prone to microphonics, though, I would think.

    Heavy absorbers will slow down transitions. It’s less about resonant frequencies but where they have to go. However, that same resonance will bleed back into the system. Absorbent materials also kill musicality. I’ll never use dynamat in a product again knowing what I know now.

    John, this was never about what you have. It’s about what you are missing.

    They are ignorant. I’ve been down the granite path. I’ve been down the wood path. I’ve been down the absorbency path. I’ve been down the grounding path. Nothing has come close to grounding.

    Mechanical grounding is an area that is so often overlooked in component and system design that it’s rather frustrating now that I understand it more. It’s such a transformational solution that there is no excuse for it.

    I like you Skip and have nothing against you, but would it not also be ignorance to assume you know more about what I have built than I do? And then rather than shoot me a pm or something to discuss, you then show your emergent arrogance by basically calling me a fool in my own thread? This was done to me back in the original thread I had when I started the first build back before you had a clue what high end audio was.

    I am proud of you and what you have accomplished in such a short span of time... I truly am. What I build, I build for me and nobody else, so if I am getting all of what I want from it, who bloody cares.

    Certainly does, and in this case it cuts both ways.... blind test between McIntosh MC601’s on B&W 802d’s at Magnolia... my amps destroyed the Mac’s by all accounts. My amps bested Bob’s 305’s at his old dealer here in Beverly Hills....

    You simply cannot claim that mine are missing something without hearing them yourself, and next time you get to L.A. you ar welcome to play with them to your hearts content. I will even send them to you to try out yourself if you pay the freight.

    I’m ending my conversation here but want to remind you where it got off track. I never should have responded as we tried this via pm a while ago and you told me then you knew what you were doing. My whole intent was to educate and improve a design for you - things that even manufacturers are blown away by but fail to implement for various reasons. The principles are simple but would take years to learn via experience.

    I have it on good authority that one of the founders of this company has purchased Robert’s stuff for their reference rig. I am trying to confirm that 100% but will need a few days.


    My invitation still stands. If you want to learn how to make the chassis work for you vs against you I’m here.

    Your posts came across as calling my babies ugly, so to speak, and after spending so long building them, not something I care to hear. I respect what you are trying to say, and as I get closer to rolling forward, I will reach out to you. Right now they are still on the sketch pad.

    What is your opinion of high mass turntables?

    Turntables are a bit of a different monster. I’m not an analog guy so I can’t comment on those. However, with other components and speakers, grounding seems to be the best solution and not by a small margin.

    The problem with absorption is all that energy has no place to go and even when it is converted to heat it is a slow process and will kill the energy of your music as a whole.
  • DSkipDSkip Posts: 16,221
    And I never said they were crap. Again, it wasn’t about what you had, but what you are missing and can gain without much if any headache.

    Its about resonant frequencies and how those frequencies get carried away from, or, transferred back in to the unit. Stone materials are notorious for being particularly bad about carrying those bad frequencies in.

    FWIW... my granite is not directly coupled to the chassis. It sits on double sided foam tape and a silicone based adhesive, so there is some isolation between it and the aluminum chassis underneath.

    Regardless of anything else they are beautiful amps.
