That's what I remember too,but I had the feeling the RCA's are more involving and the bass was a bit tighter.

That would be interesting. I have compared GE and RCA ones. It wasn't easy because it takes quite some time to change the tubes and set the offset and balance again. I thought the RCA's were the better ones, but I am not really sure about that.Good luck!

It is the Korean version.You have to look at the self price quote. Look also at the kakaku site for prices.

Not a Mk3.0?

That makes it very tricky to order a SR-007.

That's interesting, but how do we know what the latest version is?

On the site of Innerfidelity I came across this information of the SR-007. If this information is correct than it means Spritzer has a "Mk2.5". SR-007 Mk1 early version - different driver frame plus some minor material changes, older style carbon fiber box. SR-007 Mk1 late version - the version tested here and the most common of the Mk1's, S/N either 7xxxx or SZ1-xxxx SR-007A/SR-007Mk2 - S/N SZ2-xxxx, Stax change the earpads, how they sit and introduce a port to the earcups. Sound is a mixed bag depending on fit but can be fixed to sound pretty much like the Mk1. SR-007A/SR-007Mk2 - S/N SZ3-xxxx, often called the Mk2.5, Stax supposedly change the diaphragm which results in a much more forward sound signature.

The drawing is from DIY. There was a discussion which circuit is better.(B they say).I used the online calculator in the link.

After work I have done some soldering. This site gives lot of information http://www.sengpielaudio.com/calculator-voltagedivider.htm. I made an attenuator with resistors I had by hand.I used circuit B .With two 10k seriesrisistors and 5.6 parallel. The attenuation should be 11.5dB. I think it can even a bit more. 12.00 o'clock is now OK with classical music, but much too loud with modern pop music.Older pop music is not so loud.

Thanks Laowei,now I understand what Kevin meant with the Neutrik connector. The problem is I don't have enough space behind my amp.I already use angled connectors. Besides I think it is a bit overkill.I only need 6 resistors to attenuate the signal. I have done some new calculations: line input 10k, attenuation 10dB, R1 & R2 2700 ohms, R3 3300 ohms.

Don't know how to do this with the Gungnir . I am not sure about the calculations. With the 10k series risistors I calculated for -10dB 9.25k for the parallel resistor. Are these a reasonable values?

Thanks Laowei, I will give it a try, but first I have to study it.
