Got A Turntable...What Next?


I inherited my deceased dad's vintage TT , speakers and
large classical vinyl collection. He died in 92 and the stuff was still in his basement in perfect condition just
like he left it.I am now taking care of my 87 year old
mom with Alzheimers and decided to get his rig back up and running. I brought over an old receiver with a phono stage
and a friend lent me an AT cart just to see how things sounded. Now its three months later and the system has grown with used gear as shown below.

Thorens TD-125 w/SME 3009 II
Shelter 501 mk2
PS Audio GCPH
Decware SE 341.2 (6 watt) tube w/ NOS Amperex Holland
Altec Lansing "Laguna"

I am really enjoying the vinyl experience again, have a cleaning machine and i am doing it the right way.

My questions are:
I want to upgrade to a better sounding system.....should i keep any of my present gear? I feel the speakers are the weak link, they have a wonderful mid-range but lack a little in high end and bass.
Any opinions? My budget is 8-10k. Used gear is fine.
I listen to mostly classic rock, blues and some classical.

Dear Edtyre: For a tube Phonolinepreamp I can say: Atmasphere.

Rgeards and enjoy the music.

Does your SME have a removable headshell or not? The removable one has a slightly higher effective mass and may work borderline with the Shelter.

I don't have any personal experience with low mass arms and thus have only limited recommendations - I think Raul might even have some better recommendations for high compliance cartridges.

Worth trying would be the Shure V 15 VxMR, Cartridge Man Music Maker,
Audio Technica AT440ML...At least for a start!
Restock:Mine has a removable headshell.
The first cart i tryed was the AT440ML. The Shelter has much better sound its like night & day.
The 3009 with removable headshell is borderline ok. Given the effective arm mass or 9.5g and specs of the Shelter (8.1g, 9cu compliance) you get a resonance frequency of about 12.5Hz just a little outside the ideal range.

The Shure V 15 VxMR is very often matched to your arm (and difficult to get), but the Shelter is a very good cartridge and even with a poor match may be better than many MM cartridges.
Just my 2 cents, I would focus on the source first before anything else. Of course if the amp is weak than that should be taken care of, other than that, one will never know what the system is capable of until the source is optimized.
From my experience, I didn't know what my speakers were capable of until I got my vinyl rig greatly improved!
