“Hi-Res” increases this to 199 steps for finer level control. Updated volume control w/ gain adjustment and “Hi-Res” setting: The new 8-bit volume control gives you 128dB of total attenuation via 100 individual steps. Power transformer upgrade: The power transformer is upgraded to a larger custom transformer with multiple windings to improve isolation, which results in lower noise.Ĭoupling cap upgrade: The six coupling caps on the audio board between the tube stages are upgraded to premium Japanese film caps with gold plated OCC leads. The best part? The price remains the same. We’ve recently made a few changes to all new production units that make incremental, but important, sonic improvements.
#First sound reference quality preamp ii upgrade
Really, if anyone is hesitating about the upgrade they should just do it - it is almost like getting a new component, although the basic sound signature is unchanged. In addition, the upgrades to different gain amounts and more steps on volume control are nice additions to functionality. A preamp is the heart of a system and Level 2 places the unit in rarefied air as one of the highest performing preamps I've heard (and the original was no slouch). More bass, a touch more resolution, more air on top, and with that more dimension and liquidity to the music. And wow - what an upgrade! Level 2 takes everything good about the Preamp and makes it better. It has been a couple of months after getting back the MicroZOTL Preamp upgraded to Level 2. It was easier to pick up the different voices when performers were harmonizing." There was more space between the performers and vocals were less recessed and muddy when the music complexity surrounded the voices. "Details, staging, smoothness, musicality, airiness were all improved. “A more robust overall sound and smoother finish - better bass response and glossier highs.” Feedback from satisfied Level 2 Upgrade customers:
