It looks like Dale is the one true continuation of the Walsh legacy. I bought a pair of Ohm Fs back in the late 70s and powered them with a 500 watt McIntosh. It was an amazing sound. I sold them in the early 80s when I needed the cash.
I picked up a pair of Ohm Walsh 2s a couple of years ago and have a Sony STR-AV880 amplifier, which sounds OK but no longer at those lofty audio heights. I do hope someday to obtain one of Dale's new designs and a new amp, but till then will have to just go on my memories and readings.
