Favourite upgrade?

[docbot]

Over the last month I have been on a whirlwind upgrade path, from an Atom, to Atom plus Rega P6 to Rega P6 plus SN2 and ND5SX2. Wonderful, I am a very lucky chap. However, today I received one of the new Pro-ject VC-E record cleaners. Just tried it on an original stereo pressing of Time Out, which had been virtually unplayable although the surface looked clear of obvious scratches. Wow, what a difference. Must be my favourite “upgrade”! Now onto the rest of my vinyl

So my question is, what has been your, perhaps not so obvious, upgrade?

For me the unexpected vfm upgrade going from the Musicworks Flexlite to the G3 block- for a £ 1000,- lay out this added more in my system than say a £7000,- box upgrade. ATB Peter
