@antigrunge2 is right, in my opinion. I'm guessing them to be very efficient speakers. I couldn't find an efficiency rating on line for them. I have the VOTT's and drive with a SET at 6 watts/channel from Decware. The sound/music flows out of the speakers without any effort, all frequencies. We are all in search of our "perfect system" and this has me where I have always wanted to be. That said, Decware can also very hard to get hands on. Hardly ever on the secondary market and over a 1 year wait for new. A nice SET with 300b's should really make them sing. I tried a Dynaco ST-70 a Audio Research VS55 and a McIntosh MC7270. While all brought their own sound to the stage, the Decware was hands down the best match. Good luck.
Amplifier pairing for Altec Flamencos
I am considering adding a new amplifier to try out in my current system and could use some advice on choices to consider that would be an upgrade and complimentary to my setup. I have a pair of Altec Flamencos modified with the Werner Jagusch crossovers and play them with my Don Sachs preamp and a Tubes 4 HiFi ST 120 push pull tube amp. Listening source is Bluesound node 2i with Schiit Modi Multibit Dac. I have also been utilizing an SVS SB 1000 with them. I am not positive that my current amp is affording the old Altecs the level of dynamics and resolution that they are capable of achieving. My normal avg listening level is 75db with peaks hitting low 90s db. Though, on occasion, I will go to 11. What amp will resolve this question? My budget for the amp new or used is up to $3500.
