I read somewhere that the Fosi manual describes internal gain settings for their V3 monos. Is this true? How are the settings made? Jumpers? Switch? Is there an online manual for the V3 monos? P.S. I also read this: "For V3 MONO units purchased on or after August 2nd, 2024: The output polarity of V3 MONO has been revised. You can connect your speaker terminals normally without reversing the polarity." |

Agree about models having too much gain and output these days. Some brands game the distortion results with models producing 5.2V output! What kind of amplifier needs that? In my case, the line stage provides 14 db. Which is plenty given that using balanced connections, the DAC alone could easily overdrive the power amps. Like others, however, I have discovered that having an active preamp (paradoxically) really does provide a better overall experience. For reasons that engineers like Charles Hansen and reviewers like John Atkinson cannot reconcile, having reserves of low impedance drive(?) can work wonders. While still not requiring any *correction* for low distortion output with my unit. Since I occasionally enjoy listening to my vinyl collection, I like the fact that the phono stage offers 58 db of gain which allows the preamp as a whole to easily drive a mid output MC cartridge. In the HT system using a pair of powered subs, the output comes from a separate LFE channel that can be individually adjusted for output. I attenuate at the sub itself for linear output.
I ordered a 1/4 phone plug to 3.5mm stereo adapter from Azon (to be delivered tomorrow) for my Shure SE535s. The pre "bolts on" LME49720 secondary unity gain buffers to further lower output Z to front panel jack. edit: Just did my first listen. The Shures are waaaay too efficient and noise level is high. Full gain is at about 26 on the volume scale where normal operation is more like 80 or slightly higher. |
