    The Colibri “Master Signature”

    No need - I removed the screws entirely and ran without them. The copper mat is heavy enough that it’s not going anywhere. The screws were indeed the problem! I played one of the most problematic records and it ran without issue with the mat screws removed. The odd thing is the screws are...

    The Colibri “Master Signature”

    You just made me think of something - my TT has a copper platter held in place with two screws near the mid-point of the platter. Perhaps the magnet is being pulled by the screws as they pass by assuming they are magnetic. That would explain why it only happens on the second or third tracks...

    The Colibri “Master Signature”

    I believe I'm one of those three you mention. In my case, the problem has been with the cart bottoming out on certain passages, even with perfectly flat records. I thought at first that the suspension on my cart was damaged and sent it back for a checkup. When it was returned, it exhibited the...

    The Colibri “Master Signature”

    I guess it's very different in Europe - I sent mine in for a suspension tweak and it took almost 4 months to get it back...

    Airtight Opus 1, ch precision p1, Techdas AF3 premium combo but which tonearm?

    I have the Master Sig on the VPS 100 phono stage with an Emia silver SUT and it is anything but laid back ;-) This cart has so much energy across the board - I would describe the bass in my setup as cavernous in its depth along with very good articulation. In fact I was surprised at how...

    Tesla solar and Powerwall to power audio system?

    I live in California and installed two Powerwall batteries - the total cost with installation and permitting charges was around $14.5k and I got a PG&E SGIP rebate of $9.5k so the cost to me was very cheap. The batteries are so much better than a generator backup system - no maintenance or...

    The Colibri “Master Signature”

    I believe the Master Sig at standard output (1.2mV) is 36Ω - I have a 0.9mV version which is 39Ω. I got this information from a contact who reached out to his dealer in Europe. When I asked the US distributor, they gave me a standard value of 13Ω which is clearly too low given the output level...

    The Colibri “Master Signature”

    Analog Magik does include anti-skate setup - I've found this usually puts me at a much lower setting than the tonearm instructions would suggest. I can compare to the scope method if I ever have the time...

    Cartridge Set Up

    I use a USB microscope to get a baseline setting, then tune by ear. It’s a lot quicker in terms of giving you a starting place that should be close. That said, when I’m lazy, I’ll just use a bubble level to get the cart parallel to the record, then tune by ear from there. That technique doesn’t...

    Tonearm Setup: Effective Mass, Inertia, and Sound

    Agreed about getting to 9-11Hz resonance range. I use this handy resonance calculator - Vinylengine resonance calculator. I also created some headshell weights in order to dial this in on tonearms that might be light in mass compared to the compliance of a given cartridge. The weight is made of...

    Furutech Silver Arrow 2 Phono Cable

    It’s the African Genadille wood with 0.9mV option. The CB-1 is also in African ebony to match ;-) Btw - the arm just shipped so hopefully I will have the setup running this weekend.
