Winston Ma was considering reissuing some Direct-To-Disc LP's from the past like M&K's For Duke and others. He called it his "Dream Project". The idea was to create copies of the D2D LP's using some great phono cartridges from the past and recording to tape. Winston had three cartridges in his collection he though would be good candidates for the project, they were Kiseki Lapis Lazuli, Win Labs FET-10 and Audio Note IO LTD. Winston asked me and Gary Koh to check the cartridges out and advise him. The cartridges ultimately were not suitable due to their age and condition, but evaluating them was very interesting. The Dream Project never went forward, but I though member of the forum would be interested in some of my observations. If anyone has interesting experiences with great phono cartridges from the past, please share.
Kiseki Lapis Lazuli was one of the great cartridges from the past utilizing solid gem stone quality Lapis Lazuli and a real diamond cantilever. The suspension was no longer optimal so it's performance had diminished. Still, it had some of it's magic and was the best sounding of the bunch. I fantasize what the sound would be like if the suspension was brand new. It was something special.
Win Labs FET-10 is a "Field Effect Transducer" and is unlike the strain gauge cartridges that Dr. Sau Win is famous for. Unlike the vast majority of cartridges out there that generate electrical power, the FET-10 actually transmits a signal to an external preamplifier for creation of the analog waveform power. The cartridge actually was capable of performance down to 1 Hz! Although it's overall performance was noisy and not competitive with current cartridges, it had the best bass I've ever heard from a cartridge by a big margin. This was really a laboratory quality product. I can only imagine how good this cartridge could be using current technology and a DARPA budget.

Audio Note IO LTD was given to Winston by Kondo in appreciation for all the business Winston gave him in Hong Kong. This very special cartridge used a field coil for generating the magnetic field for the moving coil rather than a permanent magnet. If you look closely at the picture, you will see that it has 6 pins. Two pins were for the external DC power supply. Two wires were run from the power supply taped to the arm tube. The cartridge had ultra-low output and was played through a Kondo pure silver SUT. Again, the cartridge suspension was too old for optimal performance, but the cartridge definitely had some magic. I fantasized how good the cartridge would be if Kondo was still around to produce a modernized model.
