Scot,
Thanks for the note and link to the 9GSS video. The Luxman preamp I use has two pair of SUT so it can accommodate both high and low impedance cartridges. I run the Ikeda 9GSS into the SUT for low impedance, which provides the best match. I have not tried the Ikeda SUT, so it may well be better, but it would also require another set of expensive interconnect cables as well. At this point in my system nothing is inexpensive it seems.
I had an Aesthetix Rhea phono preamp at one time. It is an all tube unit with different gain and loading available. A great sounding unit, but too much hiss for me with low out put MC cartridges.
I also had an Audio Research Reference Phono 3, but wanted to get something with a built in phono preamp and SUT so I selected the Luxman which is a better match in my system.
My former tonearm was an Ortofon RS 309D. A very good tonearm, but not as good as the Ikeda, especially when matched up with an Ikeda cartridge.
The 9GSS sound great out of the box, but gets better as it breaks in. Mine now has a little over 50 hours on it, and is still improving
Best Regards,
Jim Perry
