Watts Audio PAM16 DAC?

[Flash53]

Someone knows the Watts Audio PAM16 DAC? This DAC was developed by Robert Watts (DPA) and is completely different in design than most other DACs. It doesn´t use typical DA converter chips but FPGA chips and discrete resistor network, Pulse-Array or WTA-Filter is the name of the technology. Also a HDCD chip is used but no upsampling. The same technology was used in some Chord DACs (DSC1500E and DAC64) and it seems it´s something similar than the DCS. Of course it´s not that advanced (and expensive) as the Chord or DCS but interesting I think. 5 years ago this DAC did cost about 2500 Euro now I can get one for less than 1000 Euro. Maybe someone knows this DAC and how good it is especially in compare to todays DACs.
When this DAC was released I saw a test in a German magazine but I never saw one until now. It seems the sound is very natural and detailed but the question is if todays DAC can do that better.
I have a TEAC VRDS 25x CD-Player and now I want going with an external DAC. Something in the 1000-1500 Euro range is what I can afford. Some years ago I had a Parasound DAC-1600, a Proceed ...? DAC and a DIY DAC here for testing but I didn´t like them in compare with the TEAC internal DAC. Now I´m trying again. I think here in Germany there aren´t very much DACs available currently, at least I have not found yet very much in my pricerange and not a single here in my area. I think the Benchmark DAC1 is not what I want, the Lavry DA10 maybe. From what I read I think about the Stello DA220 MKII and yes that Watts PAM16. Yet have to see a shop selling the Stello here. Regarding DIY-DACs I haven´t seen one yet to my liking, maybe it just wasn´t the right one until now.
I´m sure I could do some tweaking on my TEAC but to be honest I don´t want soldering on that one. I still have that magazine with the test and pictures of the Watts and from what I can see you could do some improvement with Oscon or Blackgates caps and a second transformer for splitting digital/analog power supply. Four LM317/337 voltage-regulators are used already.
