Interconnects for MHDT Orchid

I have been using an old TADAC DAC which had balanced outputs. So I had been using Acoustic Zen Matrix Reference II balanced cables. So, with the Orchid I need to switch to RCA cables. I know they make an adapter (balanced to RCA) but I read some negative things about them. With regard to what I am looking for, better soundstage and softening of high frequency treble/less high frequency brightness. 

I'm using Audience Ohno RCA cables with my MHDT Orchid DAC. The sound is smooth and balanced.

I’d highly suggest waiting until you have the Orchid burned in and see which direction you want to go from there. My guess, the Orchid is a little on the warmer side so you might wanna consider the AZ Silver Ref l or lls. They’re naturally detailed but with good tonality and huge soundstage. But again, there’s no way to gauge this without you hearing the synergy with your current electronics and cables.

1. The function of the non-oversampling R2R ladder technology will help solve some of the digital grain, and provide you "less high frequency brightness" as you are looking for. That’s part of it. Not all of it, burn-in, tubes and cables are next.

2. The stock GE 6570 or Triple Mica version of that same tube can sound a bit neutral, nice, maybe a tad tipped up on top at first ’til full burn-in, but nice and ties in directly to whatever interconnects you choose, so you are asking the right questions.

- I use the Tesla tube instead (mid level) smoothness. The WE396/2C51 is too smooth in my setup. Works for some with brighter sources and metal dome speaker systems. Let that stock GE5670 burn in for a while w/new ICs.

3. My theory is "you can easily change the tube" or "change the caps inside" for less cost than buying and trying different interconnects. Choose interconnects well w/o adapters if you can help that situation. Try CableCo for demo loaners if totally uncertain. I follow what others said, start with a first loaner pair, go +/- from there.

Thanks or all the responses, decooney, which Tesla tube did you use?
