For a second system I have been thinking of the Marantz Arch.

I'm sorry...what's a Marantz Arch?

@roxy54   you beat me to it!

try using google, it can help answer many questions.

Looks like a giant clock radio/cd player.

@whatjd  Who knew?

@whatjd   You are the OP asking for help.  Why should those who might assist have to do that?  A bit presumptuous? 

For something as obscure as the Arch, a link would have helped. It would right up there with using google. I thought is was something done on a balance beam. 👻

All the best,
Nonoise

it's groovey lookin'

how much could you sell one for if you bought it and didn't like it?

well worth $50 no matter what
