Lyra Delos Settings

Agiacco - you would be best running through all the settings yourself. Although this is tedious you will learn a lot and it is really the only way to find the optimum set up in your system. Even if you found someone with an identical system, if their cartridge allignment or VTA is different then again you may end up with different results.
You may need to adjust VTA or revisit the settings if you alter the VTA to fine tune and double check your conclusions.

Hi Agiaccio: The loading resistance for a low-impedance MC cartridge is related to the values of the capacitances between cartridge and phono stage (plus whatever amount is present at the phono stage input). The general rule of thumb is that, the lower the capacitance value, the higher the resistive loading value can be (which is beneficial for dynamics and resolution).

If you are willing to give me a few days, I could run a set of loading simulations for you. Please be aware that without knowing some of the key capacitance values, a certain amount of guesswork will be involved.

These days you can buy a digital multimeter (DMM) which can easily measure capacitance for not a lot of money, and this would eliminate the guesswork (hint, hint).

The Nordost Heimdall 2 will likewise be one meter long (3.28 feet)? FWIW, 1.2m is more common for bespoke tonearm cable.

How long would you estimate the signal wiring inside the JMW-9 tonearm to be (including the leads to the junction box)?

Jonathan - Your comments are always full of nuggets ( gold ).
Quick question, with my Marantz 7, it has enough gain ( and dynamics ) for cartridges from about .3 up. I prefer MC's that will run at 47k to avoid loading down and reducing the apparent gain. Odd thing is some MC's such as Denon 103 produce no sound at all, some sort of resonance for cartridges with higher internal impedance.
Do all the Lyra's work ok into 47k ?
What is the maximum capacitance that you feel is appropriate for a 47k load ?
I also use MIT cable extensively but am aware that it is quite capacitive. I've noticed that the more capacitive phono cables are they do timing better - are they acting as a capacitor block on the MC output ? Does this have any negative effect on cartridge performance from your point of view ?
Sorry - a few questions here.

Thanks.

Jonathan,

To answer your questions above...

"The Nordost Heimdall 2 will likewise be one meter long (3.28 feet)? FWIW, 1.2m is more common for bespoke tonearm cable." - Correct, the Nordost Heimball 2 will be 1.2m in length.

"How long would you estimate the signal wiring inside the JMW-9 tonearm to be (including the leads to the junction box)?" - I would estimate about 12.5 inches.

Hi and hope that everyone is doing well:

According to a member of the Phonogram mailing list who recently contacted Harry Weisfeld, the total capacitance for a Classic tonearm with standard tonearm wiring and the standard RCA junction is 143 +/- 2 picofarards (for the arm and box).

He also asked about the Valhalla version, and I am not entirely sure which version Harry's reply addressed. Still, at least 143 can be a starting point.
