    And that still doesn't address the matter of why RCAs have become commonplace on home audio equipment, instead of the likes of the above.

    I'm afraid that Jez can't just jump onto threads, imply that I'm wrong, and then when asked to explain, ignore me. If that's what's going to happen, then he should just ignore what I've written in the first place!

    There is more support for the use of different connections both sonically and technically. SMA connections and pre made cables being muted as preferable to anything hifi due to their extensive use for RF

    Looks like an interesting experiment for someone!

    Glad you're enjoying the AVC. It's a good bit of kit, but are you saying that it offers the same "open window" effect or "rez" (to coin a phrase from Jerry), as the GP? If so, that's an area where we'll have to differ, as I thought the GP was markedly better in that area.

    As you know, hi-fi is all about trade-offs; it's rare that you get your cake AND eat it, so you may have to trade some "rez"/'open-window effect' for accurate tone and leading-edge definition, in your quest for the 'ultimate' preamp

    Yes mate, the GP had higher resolution but the AVC is not far behind. The tonal accuracy is a larger difference. It's a difficult choice. One I won't make in a hurry!

    Ah I see... It was you writing "being muted", rather than 'mooted', that threw me!

    Jez still needs to answer my question, though.

    Heh-heh... I was trying to work out how connectors could 'mute' anything. Don't worry, I'm not awake yet myself (had a late listening sesh until nearly 2am this morning)!

    I suspect Jez was a) at the pub so didn't reply and b) meaning that balanced connection offers no advantages over single ended in a domestic situation.

    I also agree with Jimbo's assessment of passive and active preamps. I added a little Yaqin valve buffer to my Alps black passive and found the extra body I was looking for albeit at the expense of some of the passive's virtues. Still preferable though and more enjoyable than any active's I've heard to date.

    The problem with active preamps is getting a good one at a reasonable price. I can't understand why they are so expensive, the component costs are tiny compared to say an equally priced valve power amp.

    Never heard a TVC or AVC
