VTV Purifi monoblock - which input buffer to choose?

[EB1000]

Hi

I've decided to give the Purifi a chance and I will be ordering two VTV units. I'm not sure about the best choice for the input buffer. Go with the Purifi default or a different choice? Will it make any difference when fed from NAD C658 XLR output?

Thanks

Generally speaking, custom input buffers tend to result in worse performance than the standard one. Unless you've an opamp rolling addict, I wouldn't bother... and even then I'd probably just get the non-populated board to try some monolithic types.
