Just pulled the trigger on one of these babies....

One thing I've just noticed from the information provided on the graph, is that a Technics SL-1200 MK2 was used for testing purposes.

Now if the DL-S1 was fitted simply to a stock Technics arm, that would explain some of the less than favourable results... Quite simply, that arm was never designed to be used with a cartridge, such as a DL-S1!

The results would almost certainly be entirely different if the cartridge were used on more suitable tonearm.

Incidentally, changing the subject somewhat, what type of stylus do you use on your Troika - is it the stock one or have you had it re-tipped with something more exotic?

Marco.

I wouldn't say the graphs are unfavourable - in fact the frequency response is quite flat - a rising top end is common and often more pronounced than indicated here.

I'm surprised you think the arm would impact so - what do you feel is wrong with the standard arm for a frequency sweep? The mass should be OK.

My Troika has been quite heavily reworked and has a ruby cantilever and nude Geiger II S stylus (basically the same one as on your Ortofon). I also have one with the original aluminium cantilever and a Paratrace stylus.
