Nagra classic phono selects a new class a circuit pure bile amplifier architecture consisting of four vacuum tubes - two e88cc / 6922, one ecc81 / b739 and one ECC83 / b759, with a gain of 64db! (VPS is two vacuum tubes plus subsequent transistor amplification). It adopts a new generation of patent input booster cattle (based on the core technology of HD pre stage); two groups of inputs (MC / mm with boost cattle, mm without booster cattle); adjustable and customized impedance load adaptation.

And for the needs of playing the front page or old records, the front panel is more user friendly and more convenient to choose from RIAA, teldec and Columbia curves; the stereo / mono selector on the front panel can be compatible with mono in real mono mode; and the adjustable high and low gain can be easily selected on the front panel: for MC input, the gain option is 54/ 64db, for MM input, the gain option is 38 / 48dB.
The new built-in mute power supply can be upgraded through classic PSU; its sound has density and expansibility, and its pure quality is impressive.
