I am currently using a Roksan Xerxes MK1 piano black)with an Audio Origami fully upgraded (internal, external wiring, new end stub and filled arm tube,fully chromed for aesthetics) and a Ortofon Rondo Red MC cartridge. The sound is fast tight and slamming with base as I have the end stub on the tonearm weighted for base. I use this TT for Rock music and R@B. The most significant upgrade sonically was the upgrading of the Rega 250 by by Johnnie at AO, I reckon this arm would be a match for any Roksan in house arm.
I have a Systemdeck IV, had it from the eighties with a Alphason HR200 tonearm and AT OC-7 cartridge, sounds brillian too , weighs a ton and I play classical, well my Dad does on this TT. Its a bug, I`ve seen on a well known auction site, Gyrodecks, Manticore`s and Townsend all from the eighties and have to stop myself from jumping in simply to hear their sonic abilities. Ihave a Ariston RD40 which was my first TT in the mid to late 80`s , hasnt been played since 1989.
Avoided LP12 for the future when I`m truly looking to explore other avenues and I can afford to do the whole LP12, EKOS properly. Did hear a LP12 , Ittok and Troika in the early 90`s and it was superb.
