Great review Fred, thanks for the Head's Up... It's always great when any type of 'audioholic' goes bonkers over our beloved B7....(understandably so, of course). If I could side-track the thread just for a little readers' advice ?
I've been cruising a little for some fresh 300B's to alternate with my Sophia Carbons (Rectifier is EML 5u4G Mesh) and considering their (Sophia) 300B Mesh instead; any comments on how they may differ? I'm currently swimming in a transparent, well defined/articulate soundstage with utterly see-through transparency and precise imaging in a fairly first-few-rows perspective. In an ideal world I'd like to try a slightly more laid back viewpoint with perhaps a touch more warmth /golden glow while willing to give up a little of the dazzling detail...[but not too much!]. Footnote FWIW: My system tends towards the classic double-edged sword of ruthlessly revealing the recording quality...great when it is, pretty tough when it's not...
Thanks in advance.
