Regarding the Zep show in 1969, the answer is yes.
Help me pick some new or used speaker cables
Let’s say the budget is $2.5k
Speakers are (modded/upgraded) Chapman T-7s driven by a Rogue dragoN.
The T-7s have titanium tweets-which I might like to tame or smooth ever so slightly.
I listen to Qobuz exclusively, lots of Rock(Zeppelin) & house (Satin Jackets) Female soloists (Norah Jones)
Thank you audioholics!
