Yes, a cheap inductive l-pad between OPT and S2 in midrange channel. Interestingly, the frequency response of the first order Lazy Ribbon is remarkably similar to a response you posted somewhere on this site of the Water Drop with third order filter...really similar in the low end. I think I can do better with the Lazy Ribbon as I still have a slight but broad dip in the frequency response between where the S2 signs off and the RAAL picks up which the horn loading may or may not alleviate without having to lower the high pass filter from circa 10k to say 8k (and all the troubles that may bring). Worth a shot.
In hindsight I wish I had also tried the T500a MKII or MKIII, but not so easy when the RAAL transformer doubles as the OPT. Rerurn to Romy the Cat's Site
