Which LS3/5a?

No problem.  Ive been into hifi audio for around 30yrs and I still remember that one of the best sounds I ever heard was from a pair of Rogers driven by the Cary 805 mono tube amps.  I’ve heard a lot of systems and still love the midrange from the late 70’s Rogers.  Everyone has a certain sound that is for them. 

Hello, I have collected LS3/5a speakers for the last 30 yrs.  I have owned numerous pairs and still have a few.  Currently, I have a pair of Rogers setup on a tube amplifier with 805 power tubes 45 watts per channel. I have a friend who is very serious and deep into hifi audio and is mostly into current production items, not vintage components. He’s been to lots of hifi shows and dealer demo rooms.  He owns expensive components along with IC cables that retail for $2,500.  He says, my Rogers setup is one of the best sounds he’s ever heard regardless of price.  I’ve never heard Falcon speakers but I did purchase a pair of their crossovers 5 yrs ago.  I have personally found, the best sounding LS3/5a speakers ever produced use the Rifa capacitors in their crossovers.  They are silver/blue looking.  Every other LS3/5a speaker that uses other caps do not sound as transparent.  

BTW, only the 15ohm versions were the best sounding and only 15ohm used the Rifa capacitors.  There was only a few years in production where Rogers, Chartwell, Goodman, Audio Master, Ram used the Rifa caps.  Rogers used them in the late 1970’s. Rogers early production LS3/5a speakers are not the best sounding but are the most valuable.  Since I am mostly a Rogers LS3/5a collector, I do not know the time period where other manufacturers used the Rifa caps inside their LS3/5a speakers but I have seen it in some of there models.  Years ago, Chartwells were highly sought after by Asians and I believe it was because some, not all Chartwells contained the Rifa caps.  I was a member of a forum many years ago put together by the son of one of the engineers who designed the BBC LS3/5a and we talked about this issue 25yrs ago of why do some LS3/5a’s sound better than others.
