Hello fellow Modwright disciples - having been a long time user of Modwright equipment ( my venerable level II modded P1a/P3a has only recently been pensioned off, and I currently use the excellent LS100 ) I was very pleased to get my hands on a very well looked after Elyse DAC - currently on approval - for which I have acquired a small selection of valves to try before committing the purchase - I have just installed a black base Mullard GZ34 and a pair of National Matsushita PC88's (I have also ordered some other PCC88's recommended by DW himself....) - so far, the clarity, resolution and soundstaging are all pretty stunning, but bass weight/extension is somewhat lacking - this could be partly down to the valves needing some sort of breaking in period (?) but I would very much like to hear other's experiences/ recommendations, especially with regard to achieving ample quantities of deep, well articulated bass - all suggestions greatly appreciated, but I should mention that I am based in England, so don't have easy access to any of the American suppliers - thanks in advance chaps - MH
