I use an Ashley ne4400. My concern is that it's DAC might be a weak link in the signal chain. My source is the Lumin S1 with the ESS Sabre 32 bit dac chips.

Can anyone suggest eq processors with dac's of comparable quality to the Lumins?
Does it matter? Thanks

Thanks Kal, Could you elaborate a bit on why you prefer software eq?
One advantage I can imagine, is no repeating of the D to A with software...

Primarily because software that runs on generic processors is easily and economically updated in comparison to updating hardware devices.

That, too, but you can get around that.

Any particular software you recommend? Accurate? Dirac?

What is a method of getting around the extra DA conversion with hardware based
EQ? Thanks much

I use DEQ2496 as an all-digital EQ for all non-USB sources. Love the flexibility and it runs at up to 24/96KHz PCM. Sounds great with CD sources and Apple TV.

For USB input I just started to use the convolution engine built into HQPlayer. This lets me EQ playback over DSD256 and PCM 32/384KHz. This combination really sound awesome in my system.

I created both filters in REW and both feed into an ESS DAC. No extra DA conversion either way.

I'm using the DSPeaker Anti-Mode Dual Core 2.0 processor and doing additional room measurements using REW.

Initially I started out using it running full range between between my preamp and an active analog 3 way crossover (tri-amped system) but I wasn't pleased with the level of transparency set up this way primarily due to the complexity of my system. A separate power supply helped quite a bit, but in the end, I opted for using the unit for just the subs only. In fairness to DSPeaker, it was designed to work as a stand-alone pre-amp or between your preamp and amp; not like I used it. It's really flexible and does a lot. It's really simple and fast to use. There have been several software updates. The screen resolution is somewhat limited. This is one of the reasons I like REW in addition to the other measurements that it does (waterfall plots, RT-60, group delay, etc). Oh, I had an issue with a software upgrade and the DSPeaker technical support (from Finland!) is just outstanding.
