    Calling Adjust+ experts...

    I don’t. It’s unusually unclear what the software is actually doing. Even to talk about phase for azimuth adjustment is a bit weird. But when you realise that; - Green curve shows magnitude and phase in the right channel relative to 1kHz sine in the left channel and - Red curve shows magnitude...

    Periphery Outer Ring Clamps

    Yes. I really agree to the reasoning in that article. One can always argue how large the impact is, and probably the variation in LPs in combination with cantilever geometries are greater than the impact of clamps and rings. But still, a good mat, clamp and ring will probably improve all LP...

    Kuzma Stabi M

    I'm more suspicious to the phone, and to that app in general. I understand it measures the speed and calculates the deviation from 33 1/3 rpm, right? That's not wow or flutter. It's just a speed deviation which can be adjusted on the motor control of Stabi M. We are not that sensitive to speed...

    Thoress Phono Enhancer vs. Aesthetix IO Signature

    I know. It is still tubed, but you're right. The Allen Wright designs at Vacuum State also had something like 70dB gain for the mc inputs.

    Thoress Phono Enhancer vs. Aesthetix IO Signature

    Agree. And it should not be necessary. For very low output cartridges, I think it will be excellent with a low ratio sut like 1:2 or 1:4, and nobody should need more. I understand Reinhards decision to keep all circuits clean. I think it's aimed for customers using multiple tonearms, and for...

    Thoress Phono Enhancer vs. Aesthetix IO Signature

    On Thöress Phono Enhancer i assume. That is impressive. I don't know of any other tubed phono stage with 70dB gain. Must be difficult to keep it linear. On the input resistors:

    Thoress Phono Enhancer vs. Aesthetix IO Signature

    Ok, the LP-S has moderate output but very high impedance, but it will work very good. The Ikeda won't be a problem with moderate output and very low impedance. The Anna has very low output, you may need a SUT for that. In fact, just the three cartridges you mention a very different which means...

    Thoress Phono Enhancer vs. Aesthetix IO Signature

    What types of inputs do you need, i.e. what cartridges will you use? The Thöress is very versatile, but it can't handle everything and especially not everything at the same time.

    Azimuth adjustment the easy way...

    Ok, I see what you mean. I agree, there's no reference. Well, the only reference there is is the cartridge specifications. In this case, you even need to get the test record used for your cartridge specifications, e.g. CBS STR 100 for Lyra. You also need to know the exact gain applied to the...

    Azimuth adjustment the easy way...

    But that is exactly what Adjust+ is doing :) But not only level, phase also. Here's a plot of the azimuth adjustment in Adjust+: Or do I misunderstand you?

    Cartridge Set Up

    From COP to COM This issue was raised by a close friend of mine. His friend in turn, told him that he got totally incorrect VTF and after correcting it he got heavy distorsion. The VTF was set by my friend and with his gauge in the first place. It was a bit of a mystery. I've experienced...

    Cartridge Set Up

    You have to give me a day or two. I need to prepare. But I promise I will come back.

    Azimuth adjustment the easy way...

    I agree, that is totally irrelevant. If you decrease THD with 30% by altering the VTF by 1mg, then it's relevant. But if you stay within the range for a specific cartridge, that should not be an issue at all.

    Azimuth adjustment the easy way...

    I don't think that is immediately obvious. I never heard of anyone else but myself using the tool like that. You are the first I come across after using it for 10 years. Well, it does. If you get the voltage magnitude and phase from L and R channels correct, it is correct. Feickert is showing a...

    Cartridge Set Up

    I think the VTF has much bigger impact than SRA, and that it is actually when getting the SRA correct that the chance is bigger to get more correct VTF. I even think I can proove it :) I know that's quite a mouthful to proove, but at least I could outline that idea.
