Sounds light on bass
I've carried out the following mods on my sl1210
1) Isonoae feet
2) Sumiko headshell
3) Audio Technica 440 cart.
4) I had a problem balancing the arm due to the weight of the head/cart. I ordered the additional weight and now it is balanced with appropriate tracking force and anti skate applied
5) I aligned the cart with a Stevenson protractor.
6) VTA I found a bit tricky. To my eye it seems the same level whether at the maximum or minimum setting. I can't do it by ear as the deck is right next to one of the speakers, so I can't hear things accurately.
I asked my wife to have a listen from the sitting position but that didn't really work. I have ordered a tonearm spirit level to sort this issue out.
7) I have removed the perspex cover
After all this, things sound very good except in terms of the bass. The bass seems light and without authority. There is no 'slam' to the bass. To make things clear I am not after muddy distorted bass, however my large floor standers are capable of producing clean, prodigious, low bass. But I'm not hearing it.
Is it the cart?
