Tube-craft; thanks for the reply. Let me ask; you really like the sound of the resistor loaded version better? I don't have the experience to be able to judge so I am relying on your reply. So; what does it do better? I have heard the Bottlehead Paramours and think they sound pretty good except one thing I have always noticed listening to them with the Foreplay and Seduction ; and that is a certain grainy harsh sound on the mids that becomes more apparent on certain recordings. And a kind of brittle mettalic sound on certain instruments ie. cymbals and stringed instruments like violins. Since they are choke loaded para-feed I wondered what your experience is. I've always ascribed the sound to their use of SS rectifiers; so maybe thats wrong. Thanks J.R.
