Wharfedale Linton Heritage vs...

My assumption might not be correct that they are full of plasic and made in China. 

Which do you think is best to buy between these 2:

bnew Linton Heritage 85th - $1098

or

used B&W DM 603 S3 + DM 602 S2 - $1007

Your thoughts will be greatly appreciated.

“to like them both equally would be awful“

Liking both wouldn’t be that bad - then you just pick the one that looks best in your room and return the other. 

I will agree boxing things up and sending back can be a pain but It helps in the long run in finding something that sounds good to you. 

As much as I hate the prospect boxing things up and returning them I may give them an audition. Q Acoustics has a 30 day return, if I'm willing to float around $3k for awhile I can A/B the Lintons and the Concept 40 head to head. I would only hope the choice would be clear, to like them both equally would be awful.

Same thing for Music Direct - full 60 days.

Should plenty of time to listen and let your own ears decide.

Enjoy

Crutchfield will let you try them home for 60 days with full return privileges.

A lot of positive reviews on the Lintons, maybe you should try them out at home?We have all had demos on equipment that didn’t live up to our expectations, it doesn’t mean these won’t work in your system.
lots of factors determine a speaker choice - music preference, other equipment, room acoustics etc. The speakers you have listed all seem to garnered positive reviews so go have a listen and see if it’s your cup of tea.
Good Luck and have fun along the way.

find a set of used proacs or harbeths or spendors

I demoed the Lintons and really wanted to like them but I found them hard to listen to. The sound was just a total mess. Shouty, unfocused and incoherent. Something may have been amiss. The amp used was a basic a/v amp so maybe that was it who knows. Maybe some special processing was in effect. But I was very disappointed. Worst sound I had heard in a Hifi demo in quite awhile. I would not even call it hifi. More like bad mid-fi.  Would have to give it another try to see what happens.
