Hello dear Forum people, it has been a while...
After I unconditionally fell in love with my 510's, I got infected by the virus of trying to get more of the pro studio gear of Quad. I was just offered a 520 in ok cosmetic condition and unknown technical state- supposedly it works, turns on etc. but the seller does not have XLR cables to try it. So it's a bit of a risky endavour, but since it was offered to me for a good enough price to still upgrade and fix it if needed, I am happy to take the risk.
But: it's a 520 and not a 520f. Does that matter? What's the actual difference between them? Is it an earlier version? Are they technically and sonically different?
I want it for driving my second pair of LS3/5a's in the studio.
For those interested: After my 405 was kicked out of my main system by the two 510's, the 405 went into a permanent relationship with a pair of heavily upgraded and modified Celestion Ditton 15XR's which I actually picked up for free (they were on their way into the trash...) and invested in new caps on the x-over, a pair of new Morel tweeters, new wadding and a bit of dead sheet for the cabinet, a second bass driver (that replaced the passive membrane) that I found on ebay for cheap and new internal wires, and together with the 405 they are among the nicest combinations I have heard. Very, very warm yet detailed and thanks to the Morel tweeters, they sing with stunning shimmer and sparkle on the top end, yet the bass is dry, deep and precise. Who would have guessed what these old fellas could be capable of.
Many thanks in advance, Till
