NAC552 adds Vinyl experience to everything !

Posted by: rjstaines on 28 March 2018

My NAC552 adds the occasional 'pop' - it's just like listening to vinyl.

It all started a while back right after a DR upgrade;  the pops would occur very occasionally and were almost un-noticable, but recently I've noticed they are becomming more frequent... about 2 or 3 an hour.  They only appear in the left channel, never in the right.  They don't seem to be volume dependant (they sound the same velume level whatever the volume setting on the 552, I think! )

You may ask how come I've noticed the recent increase... I've been laid low since the end of January with some (so far undiagnosed) affliction that causes abdominal pain - the kind where you want to curl up in a quiet place and try to get comfortable (or die)... and guess where the quiet, comfortable place is in our house... the lounge where the audio gear is.

The other contributing factor is the arrival of the ATC SCM 100 active speakers and the departure of the NAP500, so the power amp, which I had previously suspected, is now out of the loop, leaving just the pre-amp.

So, has anyone else experienced this unwanted 'vinyl effect' - 'pops from the pre' ?

A huge "thankyou" to those folk who wished me well for the two endoscopies last Friday;  the good news is twofold...

1.  I got to see my own appendix on a large video screen (as well as other parts of my insides I'll probably / hopefully never see again)

2.  They didn't see anything of concern, so all the 'nasties' I'd been quietly preparing myself for can be consigned back to my imagination

And the downside, (I suppose you'd call it that), is that I still don't know the cause of the abdominal pain that has me laid out on the sofa listening for pops from my speakers,  but as I said before, you've given me a few ideas for possible causes which I have yet to follow up.

 

On a different tack...

A few people had told me that the endoscopy procedure (at the 'tail' end) was nowhere near as bad as I might imagine... and they were quite right, however the preparation for this procedure during the Thursday night was, for me, an absolute nightmare.  The 2 litres of  very strong laxative that you have to drink over the course of 3 or 4 hours tasted horrible (that's being polite).  The user instructions tell you to go to bed 'when you stop going - around 11pm'.  I didn't 'stop going' until 7am,  my hospital appointment was for 8.15am.  The 20 minute car journey to the hospital was undertaken with clenched everything and gritted teeth.  

The whole of Thursday from early breakfast onward without anything by mouth, except water, left me with stomach cramps through lack of food, and the complete lack of any analgesics, allowed the underlying abdominal pain (the reason for the endoscopy examination) to be... I was going to say 'raging' but that would be a slight exageration, but very painful.  So on the Friday morning I could happily have said "Goodbye" to the world, curled up, and died.

But in true NHS tradition, right after the procedure, I was given a seat in a comfortable chair, a nice cup of tea and a biscuit.  But this is not an experience I would ever care to repeat.

In keeping with the current medical tack, thanks to those who wished me well.

Had a"bilateral inguinal hernia repair" on Saturday afternoon. Operation went well. Bit of a hiccup during recovery necessitating a second night in hospital. Should be heading home in a few hours. 

Not something I'd care to repeat. Shall be avoiding the best jokes thread for a few days.

Willy.

Ps. All of a sudden I'm starting to see the appeal of streaming over getting up every 20 minutes to flip vinyl.

Willy, I’ve heard that hernias in that area can be very painful. Hope you get well soon. Need to take it easy for a while. With my RALP I suffered from post surgery bladder spasms, which I would not wish on anyone.

It's good news that you're both recovering from your hospital procedures. In Willy's situation I hope he didn't read Roger's side splitting description of the laxative process.

I didn't get to see anything when I had an endoscopy owing to the very effective sedative. However,  in another procedure I did get to see the inside of my bladder on a tv monitor. I'll leave you to wonder how they get a camera in there, but I can tell you the camera is about the same diameter as a Bic biro.

Luckily I have no experience of popping preamplifiers.

Yes I had to suppress a chortle at Roger's laxative tale. On the plus side having in the past 24 hours gone from paracetamol through codiene then tramadol and finally at 3am this morning morphine my journey home has not necessitated any clenching. Just clutching my bottle of laxative to restart things later.

Do wish someone had fixed all those bloody potholes though.

Roger was lucky he had the laxatives before the endoscopy, but he had to! Willy, I’m sure you will have memories of potholes for years to come! They didn’t even give me laxatives in hospital after surgery. I pleaded with them for morphine and got it at night. After four days they discharged me with laxatives and codeine! After a 6 hour continuous bladder spasm the first night I called 999 and got morphine, then stronger laxatives! Apparently they did not want me to strain after the surgery!!!! It was no laughing matter and I had alerted my wife to the potholes for six weeks!!
