Hi I have own OLA in walnut for the last 15 years and apart from Replacing foam surround they keep on going great
I also have a pair of Ar3a improved
I also have a pair of
AR 91 and 2 pairs of 93 and 58s a pair of
Ar2ax and 48 38s 28 and 19
I have just brought a tsw 910 due to arrive soon and negotiating on a pair of LST to complete the madness
I would rate the OLA as a reliable speaker as I haven’t needed to do anything to them
the ARs have a far better midrange and a certain sweetness in the air with soundstage to me making it more musical however I have gone through a few tweeters due to high listening volumes when I get carried away in the moment sometimes
I use solids state amps from old crown dc300 adcom 7805 Sony marantz plinius pureaudio power Amps partnered with
Conrad Johnston pv12 preamp which adds a bit of magic to the sound
I would rate in order my listening preference via direct comparison
ar3a
ar58s
ar91
ar93
ar38
ar2ax
Ola
28
19
I have them in two seperate lounges however can sync them together
And it’s something else and I thought the neighbours would complain instead they love it
