surface noise and cartridge/ phono pre questions


Ok, here it goes. I'm very green to analog but thanks to Agon, I have so far been lead in the right direction. I'll cut the bull and get to it.
I'm currently using a Music Hall 5.1se, AT140LC cart, Musical Suroundings Nova Phonomena phono pre with a DIY phono interconnect. I'm loading the cart at 50k, gain at 40db, going into a AE-3 pre. I've made many adjustments to VTA (SRA), VTF....etc. currently I'm at approx -2degrees on VTA and 1.46g on VTF. I also tried a Shure V15 IV w/ ed saunders stylus, never could get it to sound right to me.
I'm very happy with the sound now and I think it's really close to the proper set up. I have Alison Krauss "So Long So Wrong" last 2 tracks of side 2 sounding sweet!!! The problem....I seam to be getting surface noise and pops with recordings that I would think should be better.
My main question. I tried using a lower cart loading, (2k) obviously this is to low, sounds super clean, black and quiet. Again, obviously, the highs totally diminish. Any suggestions on a direction I should go to obtain this sort of quietness without losing my high end?
I'm very new to this and learning daily but if I'm chasing my tail with my phono pre, cart, tonearm compatibilty, I'm open for suggestions. The more I read on here, it's sounding like this could be the difference in a really good phono pre. I really like the sound of the AT140 and feel that it is a good match for my humble tonearm and system. I'm curious on what you guys think and suggest.
If this is not enough info, I'll try to give more.
Just a quick note, I just hooked up the AE-3 pre last night and It's really something else for such an inexpensive investment. Great match for my SET45.

I'm glad to here from Kevvwill and Nanbil that it's not going away completely on all vinyl. That really helps in knowing not to chase something that can't be reached. I know someone may chime in and say different and disagree with that. I've always second guessed it when some people say that their vinyl is as quiet as digital. I have realistic expectations. Bottom line is even when I listen to an album that sounds like a popcorn machine, if I like the music, I still listen to it and enjoy every minute of it!!!

Cerrot....That is a generous offer and I appreciate that. Unfortunately, I'm in California. Getting to demo different things in your own system is always a huge plus!!!
Atmasphere, maybe I've just been blessed with only hearing phono stages that get it right, so to speak, because that's an experience I have never encountered. As I said, I've had phono stages do different things with the surface noise, in terms of where it is in the soundspace, but that's about it.

Interesting. And admittedly, I wussed out by getting a Grado phono stage to go with my Grado Ref Sonata cartridge. Heaven!
Kevvwill, I have to admit I was quite surprised when I heard how dramatic this phenomena can be.

Turns out that it has to do with the propagation delay (the length of time it takes the signal to propagate from input to output, something that all audio circuits have) and how that interacts with feedback.

If there is a small tick at the input, it moves through the circuit with the rest of the signal, and at the output is fed back to the input, out of phase with the original. Problem is that by this time the tick, which is very short duration, has dropped in amplitude (signal level) and the 'fed back' signal may well be most of what remains. That then moves through the circuit again and the process repeats, with each iteration the tick loosing some amplitude and changing its phase. The effect is a ringing phenomena which lengthens the time duration although frequency is not affected.

Now if you have no feedback, the tick moves through the circuit without ringing. What you find out through comparison is that a lot of ticks are so small that they are not really noticed, but can be distorted by this ringing process to become quite audible.

IOW, cleaning is important but is not the whole story.
Ralph,

Thank you offering a better technical description of this phenomena. I described the effect as "ringing" but by explaining the mechanism that produces it you also better described its sound. A feedback loop extends the tick in time by means of linked, phase-shifted repetitions... that's EXACTLY what I've heard.

A tick heard through a zero-feedback preamp like mine or the ones you build sounds like a single pluck of an acoustic instrument with a minimal sound box, a small clavichord for example... plink. The same tick heard through another preamp will sound like a pluck of a heavily amped and reverbed electric guitar... PLONNNKKK!!!

I agree with these other points:
- cleaning is essential and in fact primary, since playing uncleaned records may permanently damage your vinyl
- great tip from Rotarius regarding getting VTA (SRA, actually) and azimuth right; doing this with a fine-line stylus will indeed reduce surface noise more than is possible with an eliptical one

It's certainly true that some LP surface noises simply cannot be eliminated (without using techniques that also mask the music) but these can be minimized both in number and in obtrusiveness.

As most of you can relate, the more I'm drawn to the vinyl, the less tolerable I've become of the pop's, click's and tick's.
The better you get at playing vinyl, the fewer of them you'll have to tolerate and the more tolerable the remaining ones will become. As you upgrade practices and equipment it gets better, not worse. :)
Have to agree...analogue surface noise comes with the territory...all things being equal...it is more dependent on quality of vinyl than associatted equipment...and if I have a noisey copy of something that infringes on my listening experience I simply buy another, hopefully improved copy...I don't bother with excessive cleaning methods...the effort and cost doesnt justify the means...just my experience...
