Analog I/V Stage for TDA1541
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.
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.
