Bottlehead Crack

Sony XBR has best picture. It was worth to repair. I still never seen any flat pannel that has colors so natural.

would a NAD Viso HP50 headphone work with the Crack? It is 32 ohm (which may be too low I dunno) what would be the adverse affects?

It will work but not sound it's best. The output impedance of the Crack is too high. Low frequency response will be down maybe 3 db or so

Ideally you want to sprun headphone with at least 150 ohm input impedance with the Crack.

Sine my original post here I've had my Crack for ver a year. It has the speedball and otheR mods. With the right headphones (hd600's work very well) it's a stellar headphone amp

thank you Zavato

Zavato

what is your formula for figuring the 3db down point?

I have considered the HD600s but I need them for another room as well which is not suited to their 300 ohm load.

Still the Crack is a very attractive amp and I may have to figure something out...

thanks again
