I will chime in for my regard to Marantz speakers
Heck yes there are Marantz speakers worth listening to!
mostly vintage M, HD, DS series and Imperials, as our fellow AKers have stated above. The other ones (SP series) that came later were ok, just nowhere near as good as them. Pay particular attention to the fact that all the good Marantzs were made in USA
my collection includes, 3 pairs HD770, HD77, HD66, HD880, SP1500, Model 7 MKII, M10, & DS920
I will say that another line of Marantz's worth listening to are the MKII series which were the HD/DS woofers and mids with a Imperialesque type cone tweeter with very clean highs. My Model 7 MKII's are right on par with the HD770-77's. The thing with the Model 7 MKII's is the cabinets are vinyl veneer and they do not have the bass port with Vari-Q's, hence they are strictly suspension enclosures. Nor do they have the L-pads or shiny aluminum rings. Be weary of vintage ones for sale and the seller is unwilling to divulge the fact that something may be wrong with them, all the while saying they "sound great". They almost always play dumb. I've bought some before only to find that one or two of the drivers are blown, after the seller said, oh yeah they sound great.
