Would software make the proper glow? Of course, there is a lot of voodoo and wacko stuff about tubes and tube sound. Not only in audiophile stuff, but also in low-end recording gear. A fair number of companies have solid state mic preamps or EQs or compressors with a single 12AX7 in it, and claim "tube warmth" as a result. Many of these are phantom powered, which is DC @ 48V max, and I don't know how you can properly power tubes with that little power. Most real tube gear uses 400 or 500V supplies, because tubes are great voltage amplifiers, but not so hot at current. So you modulate the voltage and then use transformers to convert high voltage at low current to low voltage at high current driving. I know that there are models of tube amps. For example, I have a Line6 guitar preamp/modeler, and it does a pretty decent job of emulating the sound of a Marshall 50 watt system or an old Fender Bandmaster. But I have no idea what makes it sound that way. I expect they have a clipping model that adds second and fourth order harmonics. I'd love to know more. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
