Is it all worth it?

Spot on, mapman. Reminds me of one of my favorite marketing taglines of all time. From Infinity, circa 1980's, when Arnie Nudell was at the helm:

“We get you back to what it's all about. Music”.

‘nuff said.

All that maters is if you like what you hear :-)

It's not nostalgia.   I 
aways thought these pretty good for the size and cost but no special attachment. 

But they are very involving speakers and very easy on the ear as long as you don't push them too hard.    It would make me question spending up to $1000 or so for a new pair of small monitors.  Good quality new small monitors these days are very small. 

It it just reinforces to me that very good sound for a music lover need not cost a fortune these days.  Some might actually prefer the sound of these to other popular modern contenders.   You just never know. 

They knew how to make speakers a long time ago, so it's no surprise that you like those monitors.  I remember the old 15" Altec coaxial studio monitors were great, as were the old JBL Paragons and others.  One of the reasons I like my Trenner & Friedl speakers is because they remind me of the older speakers I grew up with.  Nostalgic?  Who knows.  They sound good and I leave it at that.  

The sunroom they are in is12x12 has Windows on three sides and a tile floor and cathedral ceiling and is very lively. I've found that less in there (smaller speakers) works best.    The Bostons also seem to have good dispersion and fill the room with sound nicely.   Room size and acoustics largely dictate how much speaker is needed to fill it.   Plus I am running about 8K of amplification into them so they are well fed.    That's probably mostly why they sound similar but better than I remember in regards to detail soundstage and imaging.
