Upgrading an Audio-Technica AT-LP120-USB turntable

<< < (2/6) > >>

Hey Ncik - if you want, you could borrow my DL-103R and see how it sounds. I have a headshell that has screw on weights for up to 4 grams of added weight. Ishin80 is right though - the 103 may not be the best match for an arm like yours due to the compliance of the 103 being so stiff.

I did experiment with 103R on my Technics turntable and it wasn't half bad, but the 103R is capable of better performance with a higher mass arm.

I think today I'll mount the 103R on the heavier headshell and see how it sounds.

BSD2000:
We could also replace some of the parts (caps, op-amps) inside the 640p and improve the SQ a bit, if you feel adventurous.  ;D

BSD2000:
Here's a few samples of the DL-103R with a 2g weight (VTF set to 2.5g) on a really beat up Technics SL-235 turntable:

Gary Numan - Cars (Extended Remix - 45RPM)

I used a Musical Fidelity X-LP phono preamp using the MC setting. No step up transformer was used. The recordings are in 320K .mp3 format for streaming purposes.

As you can hear, the bass is severely limited and begins to roll off after 50hz or so. The mid-range is nice and clear - as are the highs. There was some oscillation in the tonearm at a few points in the song so the tonearm was resonating at a much higher frequency then is optimal. Overall, the DL-103R wouldn't be a good match for a light Technics style tonearm.

thos clips sounded pretty good but i hear what you are saying about the roll off

hmm, i wonder what would match this tt that isn't crazy expensive but would be a decent upgrade? i guess the thing i should actually upgrade first is the pre-amp to maybe a tube preamp?

I agree. Upgrading the preamp will better show off the Denon 160.
