Still at it . . .
Yep, I am still tweaking . . . I had a few weeks off after I changed the valves in my amp. Up graded to some very expensive jobbies, two sets and they did not work properly so took a full refund and installed some cheap Russian valves, less than £100. Worked well from the start, and improved as the 'burn in' went on. After 50 hours I stopped keeping count, then I has a few week cervatical from vinyl. Almost 200 hours on with Archers, radio plays and Spotify, it was time to dip the toe again. Wow, big change, rich warm, detailed sound, loads of base. So one listened, with a big smile. The running in had moved things on to a new level . . . is there any more to come? I went back over things I had tried and dumped. Revamped the method in my mind. I have been watching a Gyrodec/Orb thread. ???the Orb is better, why . . . then I thought of the new Rega 6 and its double glass platter, the extra mass, is that what helps it sound better? My P5 is modified to use a light platter isolated from the glass platter that now works only as a flywheel. I have tried massing up the glass platter directly as well as acrylic platters, both smear my sharp tight sound. So mass up the glass, isolating the mass from the glass platter, the mass is cut from rolled sheet lead, in dimension, similar to the extra glass ring under-slung glued to the P6 12mm platter . My mass disc probably weighs twice the amount and is isolated from the main platter with high density, self adhesive double sided industrial foam. It works, smooth, much smoother involving sound, more inner detail, base extension coming through as a continuous base line underpin, or stronger base line, extreme top end is very tidy. Subtleties, yes, complimenting the work I did in the summer as well as the quality Russian valves. It has cost me nothing I had all the bits in my 'useful one day box', took about a couple of hours to mark up and fashion. CJSF
