Hi Anyone know if Alto Utopia perform well in a 13 x14 x 8ft 6 in room and are they ok with valve amps. I use Micro Utopia at the moment and have always been happy with them, can be a bit unforgiving with poor recordings ,but thats not the speakers fault.Might be in a position to upgrade. Any advise. Also using Cary Aniversary 805 monoblocks with slp 98 L pre .Yes it is a very high end system and it has taken 20 years of gradual upgrading to get to this.Hoping the Altos will finish it off for me . :)
