time to change tt's

Hi everyone, I am using a michell gyro se with an Origin Live Silver with the twl mod and a Transfiguration spirit cartridge.
The rest of the system consist of a Music Reference rm9 mkll and an audio research sp9 mklll mods by Great Northern Sound with Cardas interconnects and power cable. The speakers are Vandersteen 2ce's.
I would like to upgrade the source either by upgrading my current tt or purchasing another one. I am looking for suggestions as I have no experience with another tt.
The post above was meant to begin with 'Buying a 'Classic' would be, at best, a...'
Are you dissatisfied with the basic sound of the Gyro? The upgrades do bring it up to a high level, but are only worth it if you are already happy with the basic sound.

The standard upgrades are the Orbe clamp, the tonearm decoupler, the Orbe platter, and the HR PSU. The first two are cheap to order from Analogue Seduction in the UK. The Orbe platter comes with the Orbe clamp, or you can just order the clamp, which is what I opted to do.

The PSU is a big improvement in background quietness, bass, and speed stability. I got mine for $500 on ebay, and to be honest the current import price of $900 would probably have scared me away. (To be fair, the VPI SDS is even more expensive, though it is fancier.) I believe the PSU only needs a different fuse (T1A) for 120V operation, but I'm not sure about that.

I would also get a good speed tester like the KAB SpeedStrobe.
Thanks to all who posted the valuble info, insights etc.
My system has served me trouble and allowed me the luxury of enjoying the music. I just replaced the ac motor with the new dc motor so I am looking to freshen thing up. With the info you have given me I can make an informed conclusion.
I'm with Viridian here.
Where else to go with analogue? Perhaps going for the higher class speakers to make bucks spent more efficient having no experience with the other TTs.
For the starter and for the time being this setup can easily be somebody else dream final analogue setup after which there's no logical reason to upgrade further unless enthusiasm dominates common sense.
Given the time coherent design of the 2CEs, I think they will easily reveal the quality (or not) of any upgrade one might make.

If I were looking for an upgrade after making some of the cheaper standard tweaks to the table, I'd start haunting the tonearm classifieds.

I started with an Incognito rewired RB300 on my Gyro and then upgraded to a used SME 309. While I did gain much more refinement, the Rega arm has a beefy, bold sound that I bet many people would prefer. The reason you see so many arms that are just modded versions of the Rega 25x/30x series is that they are very hard to beat at that price level.
