Amp to match Rogers LS3/5A

If you want something efficient, try the McIntosh MC240 However, you would want to use KT66 tubes instead of 5881 tubes on the MAC. You can pick up an used one in good orginal shape for $1500 to $2200 depents on the condition.

Try a Rogue 88.It will work great.

any of the old mac tube amps will work really well due to the ohm load of your speakers. my favorite is the mc-225
