Analog I/V Stage for TDA1541

[LosNir]

Hi all,
I'm currently in the process of building a TDA1541A DAC using the famous designs from raindrop_hui.

However I haven't yet decided which SRPP Analog I/V Stage to go with, my 2 options are:

A. AnalogMetric SRPP Analog Stage (6SN7)
6SN7 SRPP Tube Pre Amplifier DIY Kit (Stereo) No Tube | eBay

B. Raindrop_hui SRPP Analog Stage (6N11 / 6922)
DAC I/V conversion module SRPP tube module | eBay

Both looks promising, AnalogMetric is using 6SN7 and looks simple enough, and raindrop_hui is using 6N11/6922 and looks pretty complex (but with high quality parts).

Any input on which one to choose? Based on the tubes used, simplicity, personal experience, schematics and overall impressions.

Thanks!

I use this one as a I/V in a lampuzera 2010 dac with very good results

i use a 80 ohms resistor to convert I to V and then to the 6n3 stage. If u want more information including THD, conections, etc, just ask

Thanks for your reply.
Why are you using an 80 ohm resistor? As far as I know the Analog Stage should do the I/V conversion.
