KEF LS50 & Tube Amps

Posted by sony6060 (A) on January 24, 2015 at 15:04:15

Per my recent post I have been looking for speakers. The new (vintage lovers sin- I know) KEF LS50 have been getting a lot of praise and no one has said anything negative about the speakers. Sensitivity has been measured at 84.7db and the 8 ohms impedance does not dip below 4 ohms. In fact, I am surprised no one has mentioned the KEF LS50 at the Speakers forum per my post there.

My KT-66 based amp uses Dynaoo A431s that measure 5.6K PP at 8 ohms (not 4.3K ohms per reports) and has a stiff 1/2 amp power supply. So, the amp should drive the speakers well enough at moderate listening levels and maintain reasonable power tube loading during speaker impedance dips.

Anyone here at AA used a tube amp with the KEF LS50? I am also looking at Maggie 1.7s.

Never could understand the obsession with going to 20K hz, most here can't hear above 12K anyway.-nT - Cleantimestream 03:38:52 01/26/15 (1)

Sure, but what about that 0.25 degree shift that results? - Triode_Kingdom 13:10:23 01/26/15 (0)
