mute/aux

Posted by: ken c on 05 September 2003

i hope this post doesnt appear more than once -- have been having problems posting. lets try one more time:

Reading one or 2 posts in the thread “what records do you keep playing” got me scurrying to our loft to retrieve my vinyl copy of van morrison’s “poetic champions compose” – an old favourite. Next stop lp12 with aro/dv xx2. I was to be disappointed. Somehow, it didn’t sound as good as I remembered. Van sounded like he was just going through the motions. This was a couple of weeks ago. I dint worry too much – CD still sounded OK. I just put this down to perhaps the lp12 needs a service.

Last night, anxiety got the better of me and I decided to give the lp12 another spin. Stevie wonder’s “love is in need of love today” on “songs in the key of life” is a song I know naim weaves magic on, so I decided to try this. Oh dear! Sounds so and so – certainly not as emphatic as I recall. In fact my attention kept being drawn to what sounded like a dominant treble – the song lacked balance, I felt. This so-so sound was confirmed when I played other records. Ah, so my lp12 really needs a service….

Preparing to pack up and return the lp’s to the loft, I noticed something odd on the nac52. on the bottom row of buttons (the record source selectors) – the mono button was ON together with AUX. Normally I operate my 52 with MUTE/AUX on in the bottom array of buttons. This reminded me of the time when I A/B’d this mute/aux config and didn’t notice any difference at all – however I still use it anyway as I didn’t detect it causing any harm. But obviously, I, or my daughter, had pressed the Mono button unintentionally. So I decided to put that right. I was not expecting to hear any difference – but out of curiosity, I decided to play the wonder track again. Oh, my god!!! Balance was back. And then some. I was now aware of quite of lot of subtle nuances in this song. Also there was a much stronger sense of harmony – I could hear harmonic parts that I couldn’t before. I could hear deeeep into the mix!!! Encouraged me to sing along. The “lingering tune” was back. What’s going on? And why on lp12 source only?

It was at this point I quickly grabbed the randy Crawford cd that was on top of the xps. Played that. Ah!! CD sounds better too. A lot better. So in fact CD was affected as well and I never noticed – have been playing cd’s as b’ground music while I work. Quick change to tuner – same result. My whole system was better!!! I played records till very early this am and couldn’t get up in time for the school run …

I don’t want to understand all this. I am happy that my system is on song again. Its just that in MY system, going from mono/aux to mute/aux DOES make a difference.

Now please, please, I don’t want to start another long and boring debate on what, if any difference MUTE/AUX makes. That is NOT the point of this posting. I just wanted to share this experience with you. I am also not claiming this is a rigorous experiment either – I didn’t start out to “experiment” on anything. I was trying to track down why vinyl was sounding as sumptuous as before. In fact, it does.

enjoy…

Ken,

bascically, you have found that the mono button on the record out selectors on the 52 is crap!

It makes the main listen outs go into a semi mono, too.

BTW, I always run my 52 with the record outs muted. Apparently this reduces the load on the PS slightly. I've never bothered to A/B for any differences, but I don't have any recorders attached to the system, so why not?
