New analog system disappoints, please help

Hi,

I recently decided to get back into analog after a long break. Being on a budget I bought a used system from a local seller. The system consists of a J A Michell Gyro SE with DC motor, SME 309 tonearm and Transfiguration Spirit cart. I also bought a new old stock, factory sealed Plinius Jarrah phono stage. The Gyro, 309 and spirit where all purchased new in 2002 from a L.A. area high-end dealer and set up for the original owner in his home. They have remained there undisturbed and virtually unused since (maybe 15 to 20 hours total use)

After getting it all home I set up the turntable on a carefully leveled rack and tried the bounce test for the suspension. What I got was more like the Jello jiggle than a nice verticle bounce. I followed the instructions I found online for adjusting the suspension (several times) and although not perfect the bounce is much better. I have not touched the tonearm/cart alignment as I know little about this. I left the Jarrah set to factory default high output and adjusted the loading to 100ohms (recomended for the spirit)

After a 24hr burn in for the Jarrah I started to listen to some LP's. The sound is not bad, there is nothing obviously wrong but it sounds slightly recessed, flat and lifeless. I guess I was expecting more even from a relatively modest system like this. It doesn't "blow away" my digital source.

The rest of my system consist of Art Audio VPS DM pre, Art Audio Diavolo amp, Lector CDP-7T-MKIII and Spendor sp100 speakers. Cables are a mix of Nordost Valkyra and Quattro fil.

Any suggestions, incite or setup help would be greatly appreciated.

Maybe your phono setup doesn't have enough gain.
do you have a voltmeter to measure output from CD and from the phono stage ( while music playing )
2v to 3v is probably what you get.

What vinyl are you using to test your system.. my old vinyl quality was boring with no dynamics... so I went and bought some reference recording (new stuff 180gram pressing's which doesn't mean they will be good FYI) and WOW..what a difference... my other friends even after using record cleaners and steaming find their old collections don't get close to their digital. You have a revealing digital system and so this is a much harder comparision.

The suggestion about bearing oil is excellent!

GET SOME NEW VINYL to test..

For anyone interested, after doing a little reading an buying a few tools I was able to greatly improve my situation. Turns out that when I started checking I found out that the clamping bolts on the main shaft of the tonearm where very loose as where the lock down bolts for the VTF adjustment and the removable headshell. This resulted in the VTF, VTA and azmuth being way out. After adjusting these settings, tightening things up and adjusting the suspension some more I had a totally different machine. Sound was greatly improved in every way. I am now hearing what I expected in the first place. I am going continue to read and tinker and see if I can improve things even more.

Take the turntable to a dealer who has the ability to tune it and to also check the cartridge.
