Decware ZP3 Phono Stage Gain Issue


Hi There....I have a zp3 phono stage that I've had for a little while but only recently realized there may be an issue with it when I recently hooked it up to a Sonos port after temporarily using a cheaper phono preamp that I got on amazon. The amazon amp is an Emotiva XPS-1 and it is substantially louder, with a lower noise floor, and more clarity. It looks like it the gain is similarly spec'ed  (but I am admittedly not super fluent in specs) so I'm a little confused as the ZP3 gives me maybe about 40% less volume than the Emotiva.

My setup is a VPI Scout 1.1 with a Clearaudio Virtuoso 1 cartridge. I run that through the given Phono stage and into the Sonos Port. Any ideas here on how to get the gain that I'm looking for? The ZP3 volume is just barely acceptable when i have the sonos turned up to max volume and the Sonos input gain set to its highest level, which I assume is why the noise floor is high.

Could it be a bad tube? Is my cartridge just a bad match for the ZP3? Should I add a pre-amp? These are the things I'm considering.

I'm not sure I can help. Can you plug your TT output (TT-phono pre) directly into your Processor/preamp/controller without the Sonos. That will tell you if it is outputting enough volts. If one phono pre works and the other one doesn't (by works I mean enough loudness) I think you can conclude the phono pre has an issue. 

What cartridge are you using? The Decware phono pre will only work with an MM cartridge. You may have been using an MC cartridge with the Emotiva unit and the ZP3 can't boost the gain enough. Just a thought
