Empire 600lac and Kenwood kd 8030 (kd990)

Postby stumpy57 » 21 Jan 2010 13:38

Hi,

What do you think about mounting an old NOS Empire 600lac cart on a Kenwood 8030 tonearm ?
What about the matching ? => the tonearm of the Kenny has an eff. mass of 17g (kenwood specs) but I have seen 20 to 21g on some forums.

Is the empire a good cart ?
With what model of cart can we compare this "old lady" ?

Thanks

Alex: Technically you could compare the 500ID and 600LAC for example with the Ortofon OM20 and OM30 or the Audio Technica AT120E and AT440MLa. The Empires are pretty light trackers, though, so I don't think these would be an ideal match for an arm in the medium-heavy to heavy range.

The 600LAC is an arm friendly cartridge. I've used it with very satisfying results on high effective mass arms (AT 1005 MkII, vintage Jelco SA250, Thorens TP13A), a low effective mass arm (Unitrac unipivot), and a generic-70s medium mass Sony. Depending on the headshell you are currently using you could also experiment with decreasing the effective mass of your arm by using a lighter headshell of high quality such as the ADC magnesium one or the AT MG or AT LT.

Yes it's a very good cartridge. It's been compared favorably to some current high cost lomc and MM cartridges (check the MM thread at audiogon, but it's a long thread). I usually track it at 1.5g. Hope this helps.

Thanks guy for the reply !

But I am a little disappointed, lini says that the cart works fine or better with low mass arms the and dean man says that the cart works fine with the most tonearms.
In my case the calculated resonant frequency for the arm is between 7 to 8Hz.
Can this be a problem ? or is this freq just acceptable ?

Alex: Well, if the resonance is a bit on the low side, that's not ideal - but unless you have a lot of rather warped records or tend to have feedback issues with your system anyway, it's usually not much of a problem...

Agreed, even when I loaded up the high mass Jelco arm with a heavy Nagaoka headshell (image below on my idler) it sings very well with a calculated resonance of about 7 hz. Having said that I do prefer it with an ADC headshell on this arm...
