I've been listening to my Croft Hybryd Basic intigrated for a couple of months, great amp as I have said a number of times . . . but recently I have been feeling less than satisfied over the music presentation, 'less satisfied' is the only way I can describ it? I have been toying with the idea of having the amp rebuilt to the 'R' specification, make a considerable difereance, but finding £500 goes against the grain at the moment.
So, here we are, Christmas, sitting listening to plays, music and watching films. The Icon ST40 staring me in the face . . . 10 minuites and all was swaped over, what would be my reaction? It was definatly pleasurable, touching my weak spot for valves. I biased them after warm up, relaxed and listened. Warm, and easy to listen to, I then checked and biased then again, just to get the spot on feeling.
Sat back and listened again . . . different, power, authority, not quite so warm but still valve-like in presentation. Whats going on, the bias was not that far off the second time. The penny dropped, I had not switched back to 'triode mode', biasing is done in 'ultralinier mode'.
