Pro-Ject Pre Box S2 Digital DAC

Heinz Lichtenegger, Pro-Ject president starts by exclaiming "it's a revolution at the price point!" Built around the ESS Sabre ESS9038 dual DAC chip, the $399 S2 also has full MQA processing, up to DSD 512 and 24/192 PCM, 7 selectable digital filters, jitter claimed as low as 100 femtoseconds, and headphone jack. "It's the lowest jitter you can measure," says Lichtenegger.

The S2 was designed by John Westlake who has created products for Cambridge Audio, Peachtree Audio, Audiolab and others. The interior indeed sports a gorgeous and detailed layout, packing everything into a rather tight space. I asked to arrange for a review sample and can't wait to listen to it in comparison to pricier DACs.

I ordered one a couple months back from overseas. A very strong performer. One note MQA is USB only. The Pro-Ject was a clear winner over my older Peachtree Nova-Pre Dac. I'm looking forward to reading comparisons to more expensive offerings. Will it be a giant killer? I highly doubt it. I don't think Benchmark or Mytek has anything to worry about. However, I'm willing to bet it holds its own with Dacs $1000 and under. We'll see

Saw this article yesterday morning, did some research, ordered it from Amazon and it was delivered the same day! Put it between my iMac and Outlaw RR2160 integrated (that does neither MQA nor DSD...).

Roon recognized it immediately and Audirvana had no issues with it either, but I DID notice a few audible clicks between rate changes in Audirvana like I had been warned so I got out my trusted MacBook Pro, dusted off Parallels and after 20 minutes of updates, virus scans and reboots was ready to change the firmware.

This would have been a lot less painful had I not put all my memories of running Windows in the same forgotten bin as a circumcision, first day of school, vasectomy and the ex-wife, but it soon came back to rival all those nightmares. Finally after the update I had no issues with Audirvana clicks.

Roon passes MQA through like a charm and even gives you a shortcut to its website. Nice ad!
Can't say I have had time to do an eval, especially on the filters, but the build quality and ease of use seems to be topnotch.
