Filter brewing for the Soekris R2R

I see, there is something wrong. I will try to replicate that!

As I do not want to go further off topic, here is a dedicated thread:

Hello all.

It stated about the dam1941, that it "..upsamples everything to the final 2.8/3.1 Mhz DAC sample", If that is the case (and also is valid for the dam1021), why try to get anything more out of it? DSD128 and DSD256 will be downsampled to DSD64 anyway. Or?

Regards

I recently acquired a DAM1941, finished the hardware construction, added an excellent power supply and an AudioNote buffer with Miflex copper capacitors. Now I would like to try some filters. The thread is very long, so I dare to ask.
Which filters are the most audible compared to the original ones? What I care most about is a wide and deep stage. Maybe someone can help me?

Please can you share more details of this build? Where did you source the AN buffer and I assume it's a tube buffer?

Thanks

Personally I still use TNT’s latest filters.

Concerning your Audio Note buffer, the general opinion seems to be not to use a buffer but simply use the raw output. Sounds absolutely amazing directly into my tube pre amp.

Could you please write me the number of the entry containing the package of filters you use?
AN is a preamplifier and low gain and works exactly like yours, the RAW output is connected directly to the tube preamplifier, I also want to try this Aikido Anode follower.

I suggest you PM TNT and ask for his latest filter package. He's generally very helpful. Good luck.
