Default N-05xd

Anyone know anything more about the new N-05XD. Looks like it will launch in the summer.

The promise of a unit that could replace a preamp, DAC, computer and network renderer with a single box is quite appealing.

I hope Esoteric reinstates the digital filters in future DACs I prefer to use the FIR filter rather than the default 'no' filter

On the filters, I doubt it. Now that they are using their FPGA dac module, they have changed from filters to processing algorithms. And honestly I can't even tell the difference between them (I have N-01XD).

good to know. do you know if these processing algorithms mimic traditional digital reconstruction filters?

It's a bit unclear. Search for the K-01XD review on Dagogo site. There is a lot of information in there, but here is a quote.

“The D/A converter operation mode used during PCM playback can be set to three types, M1, M2 or M3. This changes the Δ [Delta] Σ [Sigma] modulator operation frequency and randomization algorithm used to absorb hardware error. M1 is the Esoteric reference mode. The operation frequency of the Δ Σ modulator becomes progressively lower in order from M1 to M2 to M3. The replacement amount of the randomization algorithm increases progressively in order from M1 to M2 to M3. By default, the setting is M1.”

On the DSD settings, “A digital filter is used. F1, F2 and F3 are digital filters with different frequency responses. The cutoff frequency becomes progressively lower from F1 to F2 to F3.”

Sounds like other XD units. If so, for DSD filter settings the default is 'off' - no filter used.
