High dynamic range music like classical takes it up to about 1 o'clock. With a 1.2V output on the Concero you will probably need the +18 or +20dB gain to be in these knob areas.
Sounds about right. with some of the high dynamic range stuff, I can easily max out the volume at 10db gain using the Concero. An additional Caveat to those planning on using the Concero as a converter: The 6db cut when using the upsampling filters seems to me to be a greater cut than just using the Concero as a DAC.
I believe the Nuwave puts out ~2.7-2.8v out of RCA and with the upsampling filters engaged it's almost slightly less loud than using the Concero by itself as a DAC at 1.2v. Though without the upsampling filters engaged, it does put out a full scale signal and is very noticeably louder.
By the way Maxvla, I think even you would appreciate the Nuwave with Concero feeding it. Ironically enough, it sounds more similar to an enchanced Concero, than an enhanced Nuwave. I suppose similar results could be achieved using a W4S DAC1 or similar. The W4S DACs in particular are very similar internally, since their designer used to work for PS Audio and also designed the DL III. I'll get to compare directly to the Gungnir later in April. Hopefully I'll get to hear that X-Sabre one day, to see how it compares.
The Concero is really a great DAC for the money, but I think it's true value lies in using it as a USB converter. I hope that with the DSD Concero release, they either keep this one at this price point, or release a slightly cheaper USB converter only, to remain price competitive with the Audiophillieo.
