![]() ![]() This was another component blend choice that aimed to offer the La Scala's as transparent and neutral a source as possible.īottom line, IMHO good horns should not be mated to source electronics with the aim of attempting to smooth over any possible brightness or edginess with a bunch of harmonic distortion. The high frequencies were neither granular nor dull, but held in check the slight propensity for the top two octaves of the SL700 to be too forward."Ĭombining the amps "sound" or rather the lack of it, along with some details like the amps high input sensitivity 0.775, and 137k input impedance, made it a perfect choice to be mated to a full passive preamp. This is one hell of a transparent amplifier. I am not quite talking "straight wire with gain," but their faults were minor. "Enough of the grumbles: what did the VTL 100W Monos do to the sound of my system?įirst, as any power amplifier should, they did very little. Strictly ultralinear with no triode switching or SET builds. Noise levels, too, were impressively low, measuring –90dB, unweighted, with the input shorted, this improving by just over 6dB when an A-weighting network was switched in circuit ahead of the meter."ĭesigner David Manley during this period of his life had been designing/building tube gear for the recording studio and was focused mainly on making his designs as transparent as possible rather than turning them into some sort of expensive distortion producer. "On the test bench, you could have been forgiven at first for thinking that this VTL was a solid-state design, the small-signal frequency response (1V into 4 ohms) extending from 2.2Hz to 77kHz (–3dB). He started off the measurement section of the review saying this, The VTL's I purchased was done in large part due to the measurements and listening review done by John Atkison of Stereophile. I did run VTL tube power amps for close to 20 years and my choice of them was done using somewhat unusual criteria in the face of today's trends.
