Forget the drilling and Dremeling, just spend an hour practicing how to do it. ...
Yeah, I hear you, but my issue isn't that I can't make the connection or find it difficult - I doubt anyone who has posted on this thread has a problem just making the connection. My issue, and I suspect others', is the the difficulty of getting a solid mechanical connection such that the wire and cup are pressed/wrapped tightly together - whether for reasons of joint strength and/or possibly improved signal transfer.
I have some WBTs with perforated connections like a terminal strip. They were rediculously expensive and did nothing to improve the SQ of the amp.
Yeah, I've seen those. But like you say the prices are insane. As for SQ: I can't imagine them making much if any difference (although I suspect a really poorly made connector could hurt the SQ by not making a good connection).
Tangent: I am a big fan of the WBT locking style of RCA connectors, but b/c of WBT prices now only buy knock-offs (which are never as good mechanically). About 25 years ago when I got my first "good sounding" system (Arcam Alpha CD/DAC and Arcam Alpha integrated amp, and small Linn speakers), I auditioned three different interconnect cables - one of which was a WBT cable that I ended up buying . The audio store set up the listening room with the components in my system and we swapped the interconnects repeatedly over the course of an hour. The differences were easy to hear - and so I became a believer in cables early on. Although, in retrospect, I think the WBT cable might have been a bit bright sounding - which (for me) creates the immediate impression of increased detail. But, man, would those WBTs ever lock on to the RCA jacks. Talk about a tight connection. There was just something really satisfying about that. That stereo purchase left me completely broke for a summer - I think i spent my entire grad student summer teaching stipend on it, and was left eating rice and beans until September. Priorities, right?
I guess in some ways I haven;t changed much in the intervening 25 years!
