Got a second hand ULDE, sounds very good.

My question is about the volume.

I'm using 300 ohm Sennhesier HD600 Headphones. These are the latest ones (2019).

Comfortable listening volume on ULDE is at 9 o'clock, I get plenty enough sound at this level. 

But I this find odd. I thought ULDE with high impedance headphones, you had to adjust volume after 12 o'clock? 

My ULDE is connected straight to a Marantz PM6006 (UK Edition) CD Player.

Thanks.

Yes, that's for a range of sources that comply with IEC 61938, but at 2.2 volts rms, your CD player outputs about four times that, so you would turn the volume down, as you have.
Not simple enough for Google-Bot to understand...

The Solo dial position will depend on the signal level going into its input as well as the impedance/sensitivity of the output load.
