    Diamonds where to buy in the UK?

    I have (for a price) found really nice vintage jewellery for the Mrs in Burlington Arcade on Picadilly. It's less the stone than the setting for us so YMMV &c. Sent from my BLA-L09 using Tapatalk

    Cartridge run in

    Hi Richard, That's 68 pF plus the wiring, presumably approx 100pF so in the rightish ballpark. Maybe an impedance issue instead? I've just rattled up an impedance adjuster (basically for MC carts through SUTs) into phono stages. It is proving rather enlightening! More anon, probably in a new thread [emoji106] Sent from my BLA-L09 using Tapatalk

    Cartridge run in

    I have read earlier today that Ortofon expect (some if not all of) their MM carts to see 400pF capacitance upstream. That might make this a loading issue if the issue is sizzly treble or overly bright presentation? Sent from my BLA-L09 using Tapatalk

    A quick DAC. Maybe...

    If my AN DAC is anything to go by there is magic in the trafo coupled I/V conversion stage too, though that makes most output trafos look a bit cheap in comparison... Implementation and system synergy, one easy, the other obscure. DIY is such fun! Sent from my BLA-L09 using Tapatalk

    Stupid question: What's the difference...

    How does it do this? Personally I hate floating t/ts just because they make me nervous - all that bouncing around. I prefer mass and damping to achieve the same thing, purely from a stylus safety perspective - nothing to do with SQ

    Stupid question: What's the difference...

    I suspect resonance comes from way back when things were more normal in this thread . WRT the turntable, acoustical and or mechanical coupling of the speakers to the platter/arm/cartridge assembly, howsoever caused, will lead to feedback. Unavoidable resonances in the platter/arm/cartridge assembly will amplify certain frequencies which if significant enough may become audible or even self-sustaining. The cartridge is designed to respond to mechanical displacement, so if there is feedback through the platter/arm/cartridge assembly the cartridge is correctly doing its job if it is transducing that energy into electrical energy, so it is not exhibiting microphony. The assembly might be described as doing so since in this case the undesired mechanical coupling is being translated into unwanted electrical energy, but this does not seem to be the common meaning of the term which targets individual components.

    Not really because it's just plain wrong.

    I think Rabski is saying microphony isn't microphony when it is resonance. I hope this helps Sent from my BLA-L09 using Tapatalk

    Indeed how true, and believe me I really don't [emoji16] but it's my hobby so I am interested [emoji106] Sent from my BLA-L09 using Tapatalk

    Stupid question: What's the difference...

    I was hoping someone would pop up with links to research on the effects of inertia (motor and platter assy), motor torque, any accompanying drive mechanism, and the ensuing effect of stylus drag in lightly and heavily modulated material. I have read on forums that it can appreciably slow the rotation of a turntable, however momentarily, but seen no investigation or figures. Anyone know if this is a 'thing' or if investigated and disproved ages ago? Links appreciated [emoji16] Sent from my BLA-L09 using Tapatalk

    A quick DAC. Maybe...

    I'd daisy chain it all up, have a listen, and then think "what next". The chip is nice, but the I/V conversion implementation will have a very significant effect on SQ. If this is done well then maybe worth playing around with valve output stages (trafo output or cap?). If it isn't then you've saved time and chassis [emoji16] Sent from my BLA-L09 using Tapatalk

    I can't help there. Again, Greg's your man. I imagine he can sort out loaners as well if you are considering new but can't speak for him of course. Sent from my BLA-L09 using Tapatalk
