I am enjoying my analog system, but what can I do to improve?

To the OP

After writing two lengthy posts that both got lost in the either, I've given up.

Take a look at my Technics projects, a lot of work that made only a small improvement. https://www.jkwynn.co.uk/Projects.html

This is why I say try a different deck, don't take recommendations, try and listen to other set ups and buy something you like the sound of, is the best advice I can give.

The Sound Lab are god speakers, I just question their suitability in your room.

So are you currently happy with the modded Rega P10?

"So are you currently happy with the modded Rega P10?"

I'm not sure if this was meant for me? as I can't see mention of a P10 by anyone.

My Rega Arm was fitted to a modified SL-1200 mk II. It was an improvement on the stock arm, but not night and day. It required extensive work/expense and after the experience, I would say not money well spent.

The modified Technics arm project, using a straight Aluminium tube inside a Carbon tube was also only a very small improvement over the original.

The deck with the linear tracker was a larger improvement, but there were so many mods, the only thing remaining from the Technics was the DD Motor assembly/PCB. Advanced DIY skills needed for the deck and again I wouldn't recommend going that route.

I've started looking elsewhere, to idler drives, which can have their own issues, but building the decks is a hobby for me and I enjoy the making. Not everyone has the skill, tools or time to do the same.

The Technics deck is almost an over achiever, it works very well as is and not much in the way of performance gains can be had, from the many expensive mods that can be applied. Gains are only relatively small for the outlay, which is why I think your money would be better spent elsewhere, if you want bigger differences. Expect to pay for that though.

The Audiomods arms have great value/performance ratio but deserves a better deck.
The Schroeder string and magnet design, if done as a DIY build has huge potential, or for a ready made, start at around £2.5k if memory serves.

Dear @qwin  : The OP TT is way superior to the one you own, starting but the DD motor and tonearm magnesium build material. Both looks similar but that's all, are way different .
