Once in a while I fire up my soldering iron and start a new project. At the moment it's the balanced line stage.

The result is very much better than the expectancy. The BLS is a very simple design but has an outstanding performance.

Some technical information: Build as unbalanced

Resistors: Welwyn, Vitrohm, Philips

Capacitors: Elna, S&M, Mundorf, silver mica

Elma rotary switch, Elma stepped attenuator with Vishay resistors

R-core transformer 50VA each

Alu case with granite sides, glass front , stainless steel knobs

I have added and modified some parts

Some sound impressions:

The BLS is sounding very airy with a lot of micro resolution. The soundstage is stable and three dimensional. Voices and acoustical instruments are sounding natural. The smoothness of the sound may be a little improved due to the Mundorf supreme caps.

The images are showing the BLS whilst building up and the finished preamp with my current favorite equipment.

If anyone has a question don't hesitate to email me. RBemail@web.de 

I want to thank Nelson Pass and his Crew for making such information available!

Best regards from Germany
