I have listened to NFB-10ES3 on Warsaw Audio Show in November on Shure SE215. 10ES3 is on SABRE and it was sounded very flat but naturality keeps me listening for long time.
So, I'm interesting in to purchase 11.32 for my Grado SR60i (in the future for Mad Dogs) or getting Schiit Vali + some DAC.
I'm going to listen mostly from Computer source.
I just nearly brought DYI OTL tube amp for headphones. But Grados are only 32ohms so OTL will not drive them well. DYI vacuum amps (those with warranty ofkozz:) have one very nice option that you can swich between tubes.
Bypassing DYI apms:
Which one will you reccomend for my preferences: NFB 11.32 or Vali + DAC???
NFB 11.32 will be a better choice at this price point.
Although it does have the Sabre 9018 inside with all the amazing resolution, it does sound a bit warm, which will benefit your Grados.
Another great option is ODAC+FIIO E12. Same cost, but can be used on the go.
