After almost three weeks with the TAT1 M2 in my system, I can provide some more insight.
The CSPort TAT1 is not plug and play and requires some skills for fine tuning especially the air flow management between the platter and the linear tracking tonearm as well as the levelling of the tonearm.
Several upgrades have been implemented.
A graphite Boston Audio Design Mat 2 has been added.
We compared the stock headshell against the ones from several My Sonic Lab and the Phasemation. The latter was chosen as the best fit with the Transfiguration Proteus Diamond. The headshell leads are a prototype from Elpispandora.
The stock tonearm cable has been replaced by a Black Cat Graceline Level 3 which I compared against the Phasemation and the Black Cat Graceline Level 2 cables.
In my previous post, I mentioned that we compared several cartridges. François had brought five 5 cartridges: the Mutech Hayabusa, the Audio Technica ART-1000, the Phasemation PP2000, the Sculpture A A.5 Ebony and the My Sonic Lab Signature Platinum. Though the final choice will be confirmed once I receive the second tonearm, the My Sonic Lab Signature Platinum cartridge has impressed me the most.
François came back a week ago for a follow up.
We have slightly increased the tension of the string/thread which has yielded in better speed management. This was confirmed by measurements with Analog Magik.
As François had brought back his Phasemation EA-2000 phono stage (mine should arrive soon), we also compared some phono cables between the SUT and the Phono stage. The best cable was a top of the line Black Cat from the late Chris Sommovigo (here connected to the Consolidated Audio Silver SUT).
