Hi and thank you for your inquiry. It really does come down to how efficient your speakers are and the input sensitivity of your amp(s). The unit has 15dB of gain and this can be adjusted down. Right now, the units ship with a Universal remote. We are expecting the new MWI custom remotes in by April, but aside from the cool look and feel, the action will be the same. The pulse length sent to the motor for the Alps blue volume control is set.
RE sonics compared to you Wytech Coral, I can't comment directly as I have not heard this unit. I can however, refer you to a review in The Inner Ear, Volume 17 No3. 2006/2007 - 20th Anniversary Issue, where they compared the SWL 9.0SE (non tube-rectified version) to their reference, which is the Wytech Opal. I believe you will be surprised at how favorably the two compared. They DID overall prefer the $8K Opal to the ModWright in some respects, but were blown away by the performance of our $2500 product.
Now that we have upgraded the unit with tube rectifier and are offering both the 9.0SE and 9.0 'Signature Edition' (tube rect.), I am hoping that T.I.E. will offer us a follow-up review. I believe that the tube rectifier upgrade would very much surprise them with its sonic impacts.
I hope this helps. I respect the Wytech name and their designs very much.
Take care,
Dan W.
