Phono Preamp


Hi!
I upgraded my equipment recently with a Triode Lab 2a3 integrated and a pair of Klipsch Forte III. My turntable is still a Project Carbon 2Xperience Classic, and the phono preamp it's a Pro-ject Phono Box S.

I am thinking about to change the phono preamp and wait a bit for the turntable upgrade. Is very difficult to get a demo for home test, so, according with your experience, witch pre-amp do you recommend with this equipment?

Or is better to go to the full pack and change both, turntable and amp?

In my opinion, you should not base your purchases on how good your total system is.  You should try to buy the most of a turntable and phono stage that you are willing or able to spend.  The better the front end is, the more detail and information you will pull out of your vinyl.

The better the phono stage, the better your overall experience will be.
The main issue with purchasing a phono preamp is that pretty much anything you install will most likely sound pretty good to you.  The only way to truly hear the differences is to have two or three different phono stages on hand so that you can swap them out to make comparisons; if you do this, the really great phono stages will immediately jump out of the pack.  

I was lucky enough to be able to do this kind of side by side comparison and the differences were dramatic.  I had a Clear Audio, Gold Note PH10, Musical Surroundings Nova III, Musical Surroundings LPS, Whest Three Signature and a Whest PS.30 RDT SE 2019 with the PS.40 RDT front end/suspension chassis/Titan Pro Wire Loom/PS.40 toroid core power supply.   It was shocking at how much better the two Whest phono preamps are over the group I was testing.   This all started based on a friend of mine who who had told me last year that a Whest Titan Pro was the finest phono stage he had ever heard (he had one on loan for a few months); he has used many phono stages over the years.

What is important to my listening is first how quiet the electronics are.  I do not like to put the system on with no material playing and hear noise or low level hum.  If you have any noise, that impacts the signal to noise ratio and it muddies up things.  The other things which are very important to me is how much detail the phono stage pulls out of the recording, the presence of a good detailed sound stage and the imaging.  With the two Whest phono stages, I lose the speakers; its as if the speakers are not even in the room as the music surrounds me.   I hear small details in the recordings the other phono stages don't present.

I suggest you spend the most you can on a phono stage as it will display information to the rest of your system.  And if you'd like to read some good comparisons, You can do what I did early on; go to the Whest website and look under customer testimonials.  There are hundreds of small write ups sent in from all types of users speaking of their observations of whatever model Whest they purchased against what they had been using (most of these guys had been using a lot of very expensive offerings from other manufactures).  It's  interesting material to read and I concur with what all of these guys are saying. 
I’ve been amazed by how much difference a good TT (w separate power supply, and tone arm ) can really make in SQ. Lower noise floor = more detail. If the TT is getting there, no phono pre is going to make that better. Just like it cannot improve the capabilities of the cartridge. Save the money of the preamp and more cables and go to the source. The trick is getting the most bang for the buck. my experience is once you get past the $8,000 range for a TT setup w cartridge, its diminishing marginal utility. Only my opinion 
With all due respect, I could not disagree more strongly.  I am using a an extremely resolving system with a VPI Ares3 TT, super platter option and a wonderful SME Series IV tone arm.  That is a pretty nice set up, its in the $9K range in cost and if you think that a good phono stage is not going to make any differences, then why not just buy a cheap $150 phono stage?  Save the money and just expect the TT with the fancy tone arm to do all of the heavy lifting.

I can hear huge differences in phono stages as noted above.  My brother who is a professional video/audio engineer was shocked at the performance of the high end phono stages when we swapped around the gear.  This is not subtle changes, its immense changes.  If my high end front end was doing all of the work, then we should not be hearing the improvements, but that is certainly not the case and it is certainly why so many guys tie up more and more money in upper level phono preamps.

High quality phono preamps just do it better.  They amplify very low level signals with the minimal amount of noise possible.  And based on what the designer put into it circuitry, dictates how well it all plays.


@slimpikins5 has given good advice. Any system is only as good as its weakest link. The phono preamp handles the most delicate signal in the chain. A good phono stage is imperative and will make a big difference. I have a JLTi which is made in Australia only now. (use to be Austria& sold in USA)I think You may still order it but not sure. Supposedly upgraded. Herron gets good reviews but is more expensive than the JLTi which was highly favored 10-15 yrs ago. VPI get the nod from me on TT’s
