The Concero and KEF LS50s are a good pairing. I drive my Concero of my Macbook Pro and don't feel it needs a battery setup, but with the SBT I think it would a great addition. The LS50s are very detailed speakers and demand a good source. Mine have made me neglect my headphone setup lately as they sound fantastic! A valve amp might add a bit of extra warmth to the LS50s which could be very welcome. Enjoy!
You know...the LS-50s are the damnedest speakers. When I bought them...I had a Rega Brio-R in my Office rig; an amp I really liked, had paired well with other speakers there...and I thought would match quite nicely with the LS-50s. It was "fine"...but I got the impression, the LS-50s were capable of more. I read a review, where the writer really liked them...with a W4S mINT. It stood to reason; the LS-50s are very inefficient...85db. So...more power to muscle them around, made sense. Plus, I liked the idea of the all-in-one...for the Office rig (whereas I would never give up my standalone DAC, in the Main system...lol).
I was going to pull the trigger on a mINT...when I came across a Hegel H-70, on the used market. I'd always been curious about Hegel...so I bit. I liked it better than the Brio-R, and so much so...that I turned right around, and bought its successor, the H-80 almost immediately. So I'm humming along...enjoying my H-80 and LS-50 combo, very much; when I decide it's time...to let a very nice, little IA go.
I got the Cayin M-6, when I decided to go "small" for a while. I had Rega RS-1s...and they seemed to need next to nothing to drive them; so the M-6 was as close as I was comfortable...trying a small-watt tube set-up (not quite a SET; but the M-6 is rated at 10wpc, using (4) 6V6 in an AB1 circuit). As it had been setting on the sidelines for a while...I decided to set her free, and let her go to a good home. I needed to get some pics...for the ad; and usually, when I'm selling a piece...I hook it up, make sure everything is in good working order...give it one last listen, etc.
If the very fairly stout Brio-R couldn't push the LS-50s around...I was expecting this M-6, to sound absolutely anemic; especially, coming right off the punch-above-its-75wpc-weight Hegel H-80. I will be damned; the combo sounded STUNNING! And not just "better"...but more "powerful". I kept waiting, for the effect to wear off; you know...not "better", just "different". Still waiting...lol. I took the M-6 off the market, and here she sits still.
Go figure, huh. But...evidently; I'm not the only one, that thinks tubes...drive the LS-50s nicely:
The addition of the Concero...has only served, to raise things wayyy up. I'm re-doing some of the acoustics in my Main room right now. Office rig sounds so good...I barely miss it
