I just finished a 2nd read through this thread and I spent some time with the reviews
@twister6 and
@gLer posted, so apologies if this has been covered already…
I am surprised by the very slight affect that Turbo Boost has on the monitors (Mezzo and Singularity) I have tried so far with my new r8ii. I had my studio partner listen as well while we toggled the Turbo Boost switch on and off. We came to the conclusion that it appears to provide a 1-2 volume click boost with the Singularity and the Mezzo (with the r8ii set to Medium Gain). The boost is about as perceptible as the change between class A and AB (and I agree with most here that I prefer AB, which is quite different to how I felt about my N7 and N30LE when I had them). All of this said, can someone here explain to me what the Turbo Boost is doing mechanically and how does the monitor used influence the boost? Granted, neither the Mezzo or Singularity require much power so is the very very slight boost due to transducer sensitivity? I’ve settled on Medium Gain/AB and I’ve observed the same results whether I switched to a high volume setting on Low Gain or a low volume setting on High Gain.
My surprise may be the result of how obviously the switch to P+ or Hyper Mode on the N30LE affected the output performance. So far, with my limited time with the r8ii, and just these monitors available to me, the Turbo Boost has been barely noticeable. I appreciate any enlightenment you can provide.
P.S. I updated the r8ii to the latest firmware as soon as I opened it and I notice the same Turbo Boost performance no matter what filter options I choose.
