Considering tube Monos to replace SS


I am hoping for some input on compatibility issues with a possible mono block change. I am not even close to being an EE; I rely on my ears, but I also consider (and ask for help) on the more technical aspects of compatibility, of which I am no expert. At the moment my chain consists of a Manley Steelhead phono stage, into an ARC LS-27, into a pair of Bryston 28Bsst2 mono's, driving Wilson Maxx 2's. I have been considering tube monos for some time now, and am looking at swapping out the Brystons for a pair of VTL 750 mono's. My math says it works on paper (but I am not 100% certain). I am hoping some of you with much more technical expertise can offer your input. Hope Ralph or Al can chime in, as they seem to be the most respected experts in the tech end of this hobby. Thanks in advance for any info, and have a great weekend.......

The Wilsons have always been easy to drive with tubes, which is why ARC and others have often showed with Wilsons at shows. The Maxxes are no exception despite the low impedance dip- even our amps which are OTLs (not noted for driving low impedances all that well) work just fine on them. The National sales manager at Wilson had our amps for quite a few years.

With a transformer coupled amp, use the 4 ohm taps and keep your speaker cables short in any event, so monoblocks are advised. Balanced inputs are nice (although the VTLs have XLR inputs, they are not balanced so no benefit accrues) if you can pull it off, which would allow you to run longer interconnect cables. If your gear sits between the speakers, this might be a non-issue.

I recommend something around 150 watts as a nice minimum, which should work fine in most rooms. So you have a wide range of amps to look at.
