Howdy, Super (sounds cooler than "Fly" tho that is kinda.. fly.
I'm listening to Dixie Dregs vinyl on my E30s now. They are just like yours,
only they have stacked 8-inchers, including the mid. I picked them up about 5 months ago for 30 dollars and have been switching between them and the Polk Monitor 7s. The Wharfedales can be a bit bright, but they are SO detailed.
I find if I don't get carried away with the volume, and keep it lower than about 10 o'clock on my amp-preamp setup (hafler transnova 150w-PS Audio pre also set to 10 o'clock), they sound fabulous. Once you start pushing them, even with the adjustable treble on the speakers, they can harsh on you. I have a JBL powered sub to augment the lower end. I'm going to sell off a lot of my gear, but the Wharfedales are keepers. They tend to make me smile, even with music I have heard dozens of times.
Looking forward to hearing you impressions vis a vis the JBL L100s.
