Mc 2301 amps

Room size is 14.7 x 12.11.   I own Sonusfaber strads.  Currently using the 501s with c2300 pre amp.  So 500 solid state watts,. Mc2301 tube amps are 300 watts.  But I have been told they sound better with the strads.  I just want to make sure they won't be too hot for the room and that I won't be taking a step backward.  

Thank you you for you help

Thanks Mike

Yea I would put up with a little heat, but don't want to get baked out of the room.  Amps would be on amp stands with a lot of room around them.  I'm not able to find a dealer in Dallas with them in stock so I would be taking a chance but I have herd they sound good with the strads

thanks
