You have some good ones to choose from. As mentioned I would first decide on the sound profile you desire. I will call them more resolving / analytical or something less analytical and "musical" in an acoustic insturement sense. This is probably a poor description. The Gershmans land in the latter category. Another possibility may be the Borrresen X series. By all means listen to them in person to make sure you get the correct flavor for your particular taste.
quest for speaker upgrade
good day all, i am looking for advice for my next speaker upgrade my budget is 20K
i have been exclusivley a 2 way monitor stand mount type of person but would like to make the jump into floor standers
i currently have a few pairs that i swap out occasionally
they are as follows
Diapason Micro's
Totem Model 1's
Salk sound SSM6
i use a solid state amp from YBA and i also have an older McCormack DNA 1
i stream music from Tidal no other source
currently i am looking at these models
Alta Audio Adam
Gershmann 30 anniversery Grand Avant Gard
room size 20 by 20
i would appreciate any other suggestions in that price range at this point i am leaning towards the Gerhmann mainly because they are Canadian and made locally about 30 miles from me
