Tubes and Transformers

ultra low noise tube amplifier ...looking for an "analog" sound, for any type of instrument or voice, using the best emulations of real equipment. ESR is best when the audio signal is the least compressed: probably more predictable. Comparatively, the NAM's CPU consumption is less than the total consumption of the plugins (oversampled). Among the plugins used: Audioscape(preamp), RockRuepel(amp), Manley(eq), Siemens(eq), Neumann(eq), Pultec(eq/transfo), ShadowHills(transfo), SSL(valve), Elysia, Vertigo, Telefunken ... tested on bass, guitar and vocal monos tracks... and with NamUniversal in stereo mode ?!?
