I'm not sure how that sounds, however, I remember in talking to Scott that the difference between the Tubedac and the Tubedac + was that the + used the Blackgates and some other changes to "voice" the DAC to sound more like an oversampling DAC in that it had that artificial digital "air" around cymbals and other higher range stuff. You may want to ask him if the SS + version is similarly voiced. For my money, the tubedac can't be beat!!
