Can anyone tell me anything about the Quad 50, 50E, 510, 520 and 520F? I came across the photo of 510 and 520 in an almost 20 years old translated from a Japanese audio magazine that published quarterly. About the sub-woofer designed for ESL-57, has anybody come up with the idea using SW-63 on ESL-57 as a \'mix and match\' alternative and achieved better (or worse) result? Please enlighten me. Thank you.
