Hi Fastrunner,

QED is excellent cable for the money. I have used both the Silver Anniversary XT and the QED Gensis Silver Spiral Bi-wire. I also have Transparent Musicwave Ultra, and while the Tra ...

Excellent story Karu. Horn loaded speakers and compression drivers can sound very compelling given their dynamic prowess. The Klipschorns are impressive. I've never heard the 104abs, and must admit to ...

Thanks for the excellent info Colin - very useful indeed. You mentioned silver. Is there an sonic advantage to using high silver content solder? This is marketed in some of the audio parts catalogues ...

Thanks Colin, that is a useful video on soldering. I now understand why my soldering efforts have gone awry. Flux plays a key part and I've never used Flux, explaining why I've had trouble getting sol ...

I use silver solder.... badly, mind you. Seems to work (and sound?) better than the usual stuff....

Don't do cold soldering!

Hi Gary, why do you not recommend cold soldering as opposed to hot s ...

Several members are efficient at soldering having upgraded the caps and op amps in the Kube. It goes without saying there are also experts on the boards here. I know that information is to be had on t ...
