Stromtank was launched at High End last year witht heir S5000. The Stromtank S5000 is a high-power battery pack with integrated pure-sine wave converter power supply that disconnects your audio system from the grid and allows up to 8 hours listening to music before it connects uninterrupted and automatically with the grid to recharge. The S2500 is the same concept that allows up to 4 hours off grid time. I want one!

Divaldi make headphone amps only with a diference; there Amp-01 also has a built in moving magnet phonostage. The products are Polish made and the steam punk version was visually one of the coolest things at this year’s High End show. I had a quick listen and they do sound very good indeed!
