BTW, I have the Erlechtung. It is a very beautiful piece. The external power supply is as big as my Bent.....
The pre section is as heavy as most amplifiers.
Pro's to the SL, it has MUCH better looks, and it has a MM/MC phono stage.
Pro's to the Bent, remote control.
They are both SUPERIOR pre's IMO.
It would just come down to system synergy and personal taste.
