Peter - you are funny...I'll give you that
anyway... BLA mods a lot of stuff that is not listed on their site - always call them
I had my Frontier Designs Tango modded and am ecstatic with what I got back - I thought the Tango sounded good anyways - especially for a converter that came out in 1998 but now it's just flat out a great box - we tested it side by side with my buddy's Aurora 8 and we both were surprised at how well the unit faired against the Lynx. We took splits from his Grace and Chandler in to both and recorded hand percussion, cymbals, guitars and saxophone - He has pretty good ears and lots of experience so it wasn't just potential purchase justification on my part - just good work.
I paid under $200 for the Tango and $400 plus some change for the premium mod - was more then worth for me as I did not have anything to lose really and gained an excellent 8 channels of A/D/D/A that I will definitely keep even as I move up the food chain....thumbsup
