Hi from another Suffolk refugee.

Both Adam speakers will be designed from the outset to be explicit in their reproduction and not add any false warmth or 'colour.' You do seem hell bent on adding extra colour by valves and vinyl... I think you should be upgrading your digits first as its so easy to bleach out the sound from domestic digital sources. Maybe you should be asking in pro audio shops that know the Adams and how clear they can be. Just my vibes, but when ATC were top of the tree (not sure they are any more, twenty years on), I started going to live music at local pubs to get a better idea of 'audio reality' and this helped a lot in future system configurations on all sources, especially now when money is non-existent.
