AV Decoder Advice desperately needed

[admin_exported]

Ok My kit is old, however i dont see the point of throwing away my THX amp and replacing it ( unless its the general consensus that it needs to go)

I dont particulary want to have to shell out another fortune to upgrade kit, but my Harmon Kardon ADP 303 decoder is dead and besides i now have HD audio to think of.
Ideally i suppose I am looking for a dsp or decoder unit that can accept multiple HDMI / TOSLINK and digitalcoaxial and can decode to nowadays sound formats, with I presume need to use 6 channel output direct to the harmon, i am unsure if we could use the LD Digital coaxial in (never played with this)

I really would appreciate reccomendations for this. If a new amp is required, please bear in mind do use the multiroom fnctions on the harmon. and what is the difference between THX then THX ultra and then THX select, yes the last time i would class myself up to date with AV was when i purchased this lot several years ago, so im trying to play catch up

Thanks all in anticipation of your help!!

I have seen an Audiolab 8000AP for 900 GBP, does anyone have an opinion on this.

Also i dontsuppose anyone has a more exhaustive list of cheaper end processor suppliers, so far i have found rotel and audiolab. An idea of who's good at this price would be nice also if anyone can throw me a bone

Cheers
