What Luxman DAC to replace Hegel HD11 ?

The question is in the tittle .. I own a HEGEL HD11 DAC since a while now, but I think it is not at level for my new amp Luxman 507uxII and I am not so happy about the XLR outputs (I use it in RCA unbalanced that clearly sound better)

I’d like to move to a Luxman DAC to match the amp, but hard to find informations

- DA150/250/06, all seems discontinued. good opportunity as second hand ?

- Use a CD player as D-03x or older discontinued reference (05/06) as DAC ?

- Should we expect new DAC reference soon ? (at reasonable price .. this is not the trend ..)

My main use is streaming input to coax & optical input from TV set


Thks, but I am more concerned about musicality than about parametrics. There are tons of perfect devices that finaly does not sound so well. Also I wanted to remain on Luxman. First as this would be the best match to my amp (levels, design, build quality), and second because I apreciate their way of designing through listening.

I have a luxman 550axII using a d-03x. Sold a benchmark 3L for the CD player. Been happy with the dac running Qobus. Dac just as good as the benchmark plus a top notch CD player. I’m using the xlr output on the d-03x. Sounds stellar. Makes me think your Hegel is your problem as you mentioned. 

Great. Somewhere I'd need the DAC part of D-03x (or any D-06x if it comes), but not the CD/SACD part
