David, thanks for tip on T+A's SD 3100HV.

cal3713 Have certainly read impressive things about the Aries-cerat new dac.  Not sure if I could finagle a home audition though and I no longer buy anything without.

I have researched the SW1X dacs and have come close to ordering the SW1X Dac 3 Balanced (they do have a return policy) but have hesitated because of it's lack of DSD processing.  Probably wouldn't miss it.  

My local dealer is now representing Analog Domain, so their dac maybe my next audition when he gets it in.  Some say it was as good as the MSB Select at a recent audio show. 

@stephendunn  If the T+A unit is a serious contender for you, reach out to me via PM. A home audition is doable.

Any suggestions would be appreciated.
Hi Stephen

I’m currently using an Allnic D5000 DHT dac which I’ve had for nearly three years now and have been very happy with it.

The original early models used to chew through tubes a bit but that was later rectified (pun intended) with an upgrade and the later models didn’t suffer with that problem.

It received a glowing review on Stereophile then managed to achieve the worst test results of any component ever tested in the lab which was later put down to a bad tube.

The review unit was sold on and it was never re-tested by Stereophile so it now has a dubious and mythical status.

As we all know some things can’t be tested in a lab.

There was also talk of a new unit coming out to replace it but as yet nothing has emerged from KS Park’s workshop.

Anyway, as I said I’ve been very happy with it and I have great synergy with a balanced connection to my Allnic T2000 integrated KT150 tube amp.

Thanks for your input.  Right now my plate runneth over: I'm awaiting the arrival of the latest Concert Fidelity Dac as well as the Analog Domain Dac1.

But my latest addition of the Innuos PhoenixNet conditioning the Ethernet signal between wall and Antipodes DX has bumped streaming and even file playback (I know that doesn't make sense at first) a fair level.  I've never had anything between my workaday modem/router and the DX and it shows.
