Prepress Vincent SA-31 MK

Actually, a precursor has a thankless job: between modern high level sources and amplifiers gain services are not really necessary. The universal composability sake she must so on the one hand to increase the input voltage, down but then usually again dampen them under the original value.

All the electrical kicked and hott tonally more benefit than harm, is a demanding task, which do not always succeed even very expensive designs. Vincent countering these difficulties with a squeaky clean designed circuit, which consigned the actual amplifier job Russian tubes: in the input into the output buffer stage, two double Triodes 6_N_16 in particularly low-distortion differential counter clock arrangement work. The miniaturized, just pen thick vacuum piston considered to be very durable and are also largely insensitive to Microphonics influences due to their quite big compared to the size of glass wall. At the Vincent they not work on their own, but semiconductors supporting outbound. So, the SA-31 should enforce MK high linearity and the subjective pleasant distortion of its tubes also towards something harder to driving power amplifiers or long cable runs.

A slowed down noticeably was the ELAN of the Vincent power amplifier, if instead of the expensive reference (Accuphase C-2810), the in-house SA 31_Mk had to take over the role of instigator. The fantastically powerful, pithy contoured waves of bass, including the 331 is capable, seemed now too early to break and to lose the sound image slide the combination too much in the superficial balancing and volume dropped. This is not a serious problem, because in the price class of Vincent, the competition performs no miracles. Given the enormous qualities of the amplifier AUDIO however, or their function to save all recommends to choose a better precursor – from the outset and instead either a passive switch/regulator of a la Creek OBH-22 or a controlled source (T + A MusicPlayer, Linn Majik DS, Sonos ZP-90) to connect directly.
