Anybody use a single ended component with one that is balanced?

My Yggdrasil sounds far better using the balanced outs, but my DS2 prep and ML 27.5 only have SE inputs, so I have a balanced to RCA adapter coming from the Yggdrasil. You can get a straight adapter or one with the XLR on one end and an RCA on the other end.

Mine;

I never heard much of a difference between se and balanced on Bryston and Anthen amps but I heard a huge difference on my Pass amp when I switched to balanced inputs so I’d say it depends on the design 

I have run my Pass diy Amp Camp monoblocs in both, each time with a Pass diy preamp — the Zen Balanced Line Stage  and the (SE) B1 Korg Nutube model. (The DAC is also balanced output.) The ZBLS has both outputs, but I think the Amp Camps definitely sound best in balanced. The B1 has only RCA, so no comparison, but what a sweet sound. 

The OP is talking about running the XL output from the pre into the RCA input of the amp.  That will produce sound.  It may not be optimal.  

OP should use the RCA outputs on the preamp if it has them.  Or use a Henry Engineering Matchbox or a Tascam adapter. 

Yes the pre has them. So it would be rcas from the amp, which is all it has, to the rcas on the pre, which has both rcas and balanced.

I could also use the neutrix adapters which avanti above suggested. 'At the amp I use a neutrik female XLR to male RCA cable adapter.'
