Pro-ject speedbox: Is improvement worth the $ ?

Well said Zd542!
Stop spending and start listening!
Your Slee is far better than any entry level phono preamp usually paired with your current analog set up(2.2LE and 2M Blue) Good! You will get the most out of it.

At one point I was "up there" spending lots of $$$$ with the likes of Linn, Conrad Johnson, Audio Research, JennaLabs, Spendor, etc.

Now I'm back "down to earth" (less money, more synergy) with a system that I love to listen to for hours!!!

There is plenty of great stuff out there at an extremely affordable price. Don't get carried away with the "advertisement syndrome" and trust your ears!

Happy listening!

LOL. Yes, I've been doing this audio thing for a long time. I've been through my share of ups and downs, buying selling, failed equipment etc, so I know what the madness is like.
Regarding the rest of my system, I have no intention whatsoever to change anything. I'm the most content I've been in 20 years. I've wanted to pull the trigger on vinyl for quite some time and I figured what the hell, now's the time.
I've not only purchased some vinyl but have been fortunate enough to have a couple friends (non audiophiles), give me their unwanted LPs, mostly jazz, some classical and other genres.
I just fitted my table with the Ortofon Blue only to find out it's too heavy for the factory counterweight. I just ordered a heavier weight from NeedleDoctor. Whow knows? Maybe this setup will satisfy me for a while....I really wouldn't mind hearing what bumping up to the $1,500-$2,000 range would be like though.

I just picked up the Phoenix PSU mentioned towards the top of the thread for my Nottingham Ace Spacedeck. I set the speed using a Kab strobe, and I am very happy with my purchase. While not a "night and day" difference there is a palpable improvement in all of the typical areas that everyone touts with a stable power supply: bass, PRAT, noise floor, and fine detail retrieval. They do work.
