Graham, the fact that the cellos or also other groups of instruments are not so forward as other systems is not because of the loudspeakers. That depends on the amplification, especially from the phono stage. It is a pity we didn't hear the Leehman's  silver cube because everything becomes so more crispy and forward to you but, as I wrote several times, I wan't the music as if I were sitting in the 7th-10th row of the concert hall with lot of ambience. I don't want to hear all the groups at 2 meters distance (direct music). In this point my system is different to most of the others because nearly everybody wants the music to be as sharp and crispy as possible (clinically sharp I would say): I don't want it like that.

I didn't listen any more to the Leehman's phono stage because it was for me too sharp, the cellos were so near and present that I could touch them! In that sense the Groove had much more "ambience" but again I mustn't forget that it had a far too low impedance for my cartridge so maybe with the right one it would have sounded more crispy and forward. I hope not for the unit, because then for me it would be comparable to the  average of the other units on the market.

The Klyne, instead, has a very nice ambience, for somebody it could sound "dull" but it has a vey nice image (at least for orchestral music).

The Walker phono amp  is so far better than any other but since its price is so far higher I will not comment on it except that the instruments are also not so forward as most of the people would expect them to be.
