Charles- Oh, my. I guess I really need to update my systems page. I have not used the Merlins in quite a while (anyone wanna buy a pair cheep!!!)and the Wavac amp is long gone. I see it kicking around on the 'Gon every once in a while, either that or there are lots of WAVACs w dented power xformer covers where the hold down screws tore loose during shipping. But I digress. The LD+ amps are driving a pair of DIY open baffle speakers I bought from another 'Goner. Very nice ribbon mahogany baffles. Feastrex 5" field coils w whizzer and phase plug rolling off naturally in the bass to a pair of 12" subs mounted on each baffle. The subs are driven by 500 wpc Class D plate amps. I'm loving the tonality of these speakers and you basically get most of the advantages of a full range driver w/o the trade-offs. The one down side is that I know three AC outlets for each channel downstream of the pre-amp. One for the field coil PS, one for the monoblock and one for the subs. Add in the pre-amp, transporter, headphone amp and disk player, and it's been a bit of a hassle. And lots of places to make a mistake in hook-up!
