I also own a pair of rare Clements Reference RT-7 speakers (purchased about one year ago, unseen, unheard, out of State of Connecticut). As you know, the rated speakers' efficiency is 88 dB, and the nominal impedance is rated at 6.5 Ohm, two-way system. I believe that there is not an easy answer to your question, if you budget is limited. On the other hand, not all expensive power amplifiers would automatically be good matches for these hybrid type speakers Clements RT-7. They might sound properly with either a good solid state amplifier or with a tube design. You will have to do more research, tackle different options and assume a certain risk when buying another amplifier, in case you won't be able to do a listening test before making a final decision (that would be actually the only good thing to do). Basically, you can try any high current power amplifier rated at a minimum of 100 watts/channel/8 Ohms in connection with the Clements RT-7, and see what will happen. I could submit you a list of several power amplifiers I know very well you could use with the Clements RT-7, but I am afraid all will be out of your range price (actually it is not clear what is the high limit of your amount for a power amplifier). Again, try, experiment and assume a certain risk (we all do the same eventually). On the other hand, if you believe the Clements RT-7 don't sound right for you with your present power amplifier, it might also happen that you don't like their sound too much, therefore you will have to replace them by other more enjoyable and listenable speakers for you. The Clements RT-7 are very musical speakers, but also with a very transparent, delicate, refined sound from bottom up, quite neutral on vocals (although with just a bit of warmth added) plus with a signal that seems to come from only one driver. They have a unique and special sound to me, practically different in a few ways from many other speakers I've heard (in the sense that they are quite impersonal and neutral as presentation, hard or almost impossible to be recognized by their sound using a blind method). In this context, you may also want to try a direct comparison in your setup and home, between Clements RT-7 and another pair of speakers you appreciate or know very well, so that to better hear the differences between both sets of speakers and make a final decision before letting the Clements RT-7 go. Let me know please if you need any more assistance or guidance. Good luck! Emil - Hartford, CT, USA
