Normally I would have dismissed this post. But guess what I have spent the week doing. Trying to diagnose a nonfunctional LED on a 10/10 integrated bought on this site! Photo or not, the seller ought to have noted that. Shame on him. But yes, a photo done as you suggest could have saved me some grief.
Buyer's request. If Sellers could list photos of units on with lights.
There are many very fine components for sale on AudiogoN. Something that would be good for me as a Buyer to see would be a picture of the front of the unit with the power/lights on. More helpful for receivers, tuners and such. Not a big deal, but some of us have purchased units with lights not working, not as big a deal as a channel not working, but something that would be good to know.
