Placed an order for a NFB-10WM with both input filters and Digital Interface. Wasn't sure about getting the DI at first as I don't know if the NFB-10WM is resolving enough for me to benefit from the DI (and how apparent the poorer quality of my digital sources might be) but as Audio-gd offered me the discount for ordering with the NFB-10, I decided to go for it. I did not opt for the separate PSU.
Haha, good one. I think you'll like it.
Then I discovered that there is a 1 PPM TCXO upgrade (mentioned above no less). I sent an email to ask if I could modify my order to include this upgrade. But I was wondering about the opinions of those who have auditioned a pre/post TCXO upgrade for the DI. As I understand it the TCXO upgrade will only be beneficial when upsampling (to 96khz with DIR9001 or 96/192khz with WM8805).
There is a TCXO for NFB-10 and one for DI. The DI's is only used for upsampling, and costs extra. IMO, save your money on the DI one. The NFB-10's was upgraded in February and is used all the time, no need to upgrade it (that's what they're talking about above)
Also, I'm uncertain whether I should opt for the DI with coaxial input (version A). I will mostly be using the NFB-10WM with my PC as a source and have the option of coaxial out from my sound card (HT Omega Claro Halo) or USB...
Anyone care to offer suggestions as to what config of DI I should get?
Definitely get the one with SPDIF in, it's supposed to be a very good reclocker (and your sound card should be good already). Also, look into upgrading the hex inverter for the best $2 upgrade ever.
