Willem. Thanks for your link to the chromecast analysis at Archimago on the iPhone 7 discussion. I thought I would reply here so as not to hijack that thread. Archimago is not a website I had come across and clearly the writer knows their stuff whilst also remaining open to new evidence and peer review. Very refreshing. I have since read a lot of the other pieces on the site and enjoyed them as well and this has given me another perspective to consider, so thanks again. I still can’t agree that the DAC inside chromecast is any good though!! 😄
"...unless your pre amplifier’s input sensitivity is low enough to handle 2V without clipping."
Thanks for the link. How do you compare streaming music using iPhone analog output -> to preamp vs. Streaming via Chromcast -> preamp?
I’m however not sure if I follow the statement I pasted above. If I’m not mistaken, the 2V is the industry (I think THX) standard for unbalanced analog output for most if not all digital source equipment and the downstream components, preamplifiers in particular, should all be able to handle this level without clipping. Actually, I don’t even recall seeing input sensitivity specs - assuming you meant input voltage sensitivity, not input impedance, even mentioned in preamplifier data sheets. However, the concern around input voltage sensitivity can come into play for power amplifiers, and is usually published, since a very low input voltage sensitivity, as defined by the voltage to deliver maximum output, could cause overload when presented with the nominal 2V input, e.g., an amplifier with a 0.5V sensitivity, etc. Makes sense?
