At the end of the day, we all take something from the discussions and I really appreciate it.

To be honest with you I am "Half Full" kind of person when comes to Audiophile world because I don't have enough resources and experience to elaborate all the finest details. Most are being quoted from other sources from the net which I choose to be more objective and evidence based opinion, if any.

I think we should use our gears to enjoy music, and not to disapprove the joy of whole experience of using hardwares and spiritual imaginations.

Watching her from the beginning is like watching your friend's daughter growing up as you were aware her shaping up.

She was shy, overweight but talented young teenager but gradually she became the Las Vegas Diva.

She may not be as fresh and exciting she once was but I am glad I saw her live in Royal Albert Hall.

Thanks for the input which is much appreciated.

"彈弓壓力不會改變"...Are you sure? The force from the top platter may not change much but technically when you play different weight of a record, 90g, 120g, 180g, 200g. The compressive force has, though very subtle, changed and in turn it will change the compression springs it will store and release energy.

The key is the "Spring Constant". I don't know the data from Linn. However, many LP12 users have been advised to re-calibrate/adjust the springs yearly just to make sure that it is still "constant".

I am not a technician so I won't even dare going to talk about Temperature Effects, Fatigue and Spring Life, Stress Relaxation, Spring Rate and Load vs. Deflection...and so on.

These are science. That said I believe listening to music combined with gears is an art.

It's an art of human input, machines and environment. Each gives different ingredient into this experience.

And times and times again, we argue that it may not necessarily be explained logically with science. Not everything is in need of nominal measurements.

May I quote again " 那一大「抽」嘢的重心升高 x mm 後，究竟聲方面會變好、變差、還是不變？
- 答案：很簡單，由發燒友自行去體驗、判斷，過發燒癮 ".

With the SAEC 407/23 arm I thought the sound was a little "tight" and it has to be "loosen" a little bit to allow more "Air" in the music.

I normally put a acrylic plate(or a flat record) on top of the platter but this time I just use the felt, just like the LP12.

I also un-turn the nuts on the springs by 3 half turns and I think it sounds much better(may be just mentally!!!)

May need more tweaks but settling for now.

Though I use CD and Digital Files with a cheap Schitt DAC I am still very much a vinyl records enthusiasm so it's time to use two turntables again.

So I have two Ariston turntable, one RD11s and the other one RD80SL.

RD11s will be using the Fiedelity Research FR-54 heavy arm with Denon DL-102 Mono cartridge. The RD80SL will be using the SAEC 407/23 and the Ortofon 2M Blue.

I used to own many Linn LP12 and still have many parts. I had upgraded the springs on Ariston to the Linn ones which are much stiffer. It still needs more adjustment with the springs to get the right sound.

More music with my second Ariston turntable, especially females vocals as I was tidying up the female vocal collections.

I haven't heard some for some times now, so more to come soon.

Richard,

I have used the Systemdek and the ADC LFM-2 (upgrade version of ALT-1).

The materials on the Systemdek's plinth is something I didn't like. It feels like glue of sticky stuff. That said it was a perfect match with my Hadcock GH-228 Export which I used at eh time. It was so musical.

However, the ADC is built from the late 70's to 80's and is mainly for the popular low mass MM cartridges most people used.

Your Denon DL-103R is a Medium/High Mass MC and I am afraid it may not be a prefect match. However, if you have them why not installing them to try out.

I used the ADC LFM-2 with a heavy Toshiba Direct Drive. Funny enough this deck is heavy but it will only sing with low mass arm, like ADC, Hadcock, Mission 774 and Infinity Black Widow.

I bought the ADC specially for the Toshiba. I had good result with a very light weight Benz Micro MC Gold.

If you have more time and thougt you could try it too since it's a very cheap but good sund cart.

Thanks for the kind words and sharing of your experience is much appreciated.

Perhaps people at R33 know that I am everywhere here with many threads. Guess life in the UK is too simple and quiet.

Life goes on and music will stay with me for a long time...........
