Henry, interestingly the Gamut is known for it's expansive imaging. Could that be partly the result of it's very simple signal path? I don't know, I'm just intrigued. As a former dCS owner, I konw there are qualities that are quite exceptional, although I doubt I will ever own some again, the price performance ratio is not right to these jaded ears these days.
Again it's a case of finding the qualities that appeal to you, but the Tact gear certainly has some that I miss, and which I feel are class leading (not bad given the price). I have seen a few comments regarding the Bristol show setup being an improvement. This is encouraging, although I must add that it was exactly the same units as last year being used, so maybe it was just a case of different mood/room/competition.
The SDA on the bass does seem to give the sound a bit more life and bounce. it retails for just £1199, which, if it is really good, suggests prices are coming down. Good news.
So cat out of the bag time, I'll have a full Tact setup again soon! The reason has as much to do with circumstances as anything. I am moving to a small flat in an old listed building, I need a system that does not need to be played loud, and that controls room resonances to prevent the sound leaking out of the room. This is one advantage of the RCS system, and the low noise floor of the S2150. But first, a trip to warmer climes beckons! So I wish you well and may well check in at odd times of the day!
Cheers
