Advice on next step for vinyl chain


Hi everyone. I have been listening to digital and working on my digital setup for a few years now. Recently I inherited an old Kenwood turntable and I have a pretty large record collection from earlier years. I have been trying to set up a vinyl chain. It has been a real joy - even liked the pops and scratches at first. Can I ask some advice about cartridge choice, or even whether a new cartridge is the way to go? The current chain is: Kenwood KD-5070, Ortofon Blue MM cartridge, Parasound JC3+ phono pre, ARC LS25 II preamp, McIntosh MC 462 power amp, either B and W 803 matrix II or Celestion 700 speakers. The B annd W are a bit sharp and fatiguing, so I will be looking to switch to other speakers before long, something with the upper end of the Celestions but with bass (Harbeth?). I listen to big classical, chamber, classic rock, jazz, opera…

The gain on the vinyl chain is high. Have to keep the pre almost all the way down. The ARC is marginally better than using a passive pre. Thinking a moving coil would be a real improvement. Is that the way to go? Which cartridge would be a match? Thanks a lot for your help.

IMPEDANCE of MC Cartridges are not absolute, but there are guidance formulas and Maker's recommendations.

ANY MC Cartridge: do the math, i.e.

Hana before you choose between the ML and the SL

ML, slightly lower signal strength 0.4mv; much lower coil impedance 7 ohms; HANA recommended load more than 100 ohms. A bit lower would be ok, i.e. 70 ohms

Hana SL, slightly higher 0.5 mv signal; much higher coil impedance 30 ohms; HANA recommended load more than 400 ohms, a bit lower 300 ohms would be ok.

a SUT, best, one with separate adjustments for signal strength and impedance would be good, you could get a lower signal strength and the proper impedance.

You could use the SUT output with your existing MM Phono Input, where the RIAA EQ takes place.

And you would be set for future cartridge choices.

xFactors (signal increase) (you want a lower signal increase to use your existing chain)

.....................................

existing 5.5mv is too high (unless you change your Phono Stage)

Hana ML: 0.4 mv: if xFactor is 10 (+20db), signal is 4.0 mv

Hana SL, 0.5 mv, if xFactor is 8, (+18db) signal is 4.0 mv

....................

example of why separate adjustments for signal strength and impedance is advantageous:

My Fidelity Research has 4 optional choices, lowest is 10.55 xFactor; however the impedance is directly related to the xFactor and is 423 ohms.

Hana SL 0.5mv x 10.55 = 5.28 mv, too high for your existing set up, 423 impedance is good.

If ML, 0.4mv x 10.55 = 4.22 mv, a bit lower, perhaps low enough GOOD, BUT, the impedance is 423, much higher than recommended 100 ohms

......................................

Ortofon T30 SUT has 5 options, the results are like mine, none have proper combo of gain and impedance.

My post was blocked by a moderator - it was only letting people know about an interesting comparison of passive preamps, with extensive measurements. Wonder why that was not allowed? Didn't push any of the buttons about profanity or being mean etc etc. I tried to include the link (to ARS of all places) but that was blocked first. Then even a text telling people about it was blocked. There seems to be no way to ask a moderator why something was blocked. Just saying.

Kindly note the Contact Us link at the bottom of every page. It works.

@arhgef don't take the blocking personally. It could be any number of not very good reasons, mainly how the rules were configured. We have to live with and accept the quirks of the site

Kind of you to say so. It was a bit disturbing for a few minutes, but audio has distracted me - my refuge as always. :)
