…Those other posts are full of assumptions
respectfully I would submit that determining the SPL and maximum power the OP is using currently, would be germane as to whether more power is needed.
Like the OP, I too have a Dialogue Premium HP. It seems to pump out 90 dB(A) as measured with an iPad NIOSH app, at ~9’ in a room that is big in spatial volume… and it sounds “o’roight” doing so.
And my speakers are perhaps a bit less efficient than the OP’s??
There are 2 problems with those Sopra 2 speakers:
- The load is a bit difficult to drive as. It is low impedance and also the phase angle gets high.
- The distortion is low, which is good. So they tend have a bit of a quiet sound, and to me they begged for the volume to be turned up.
(When I heard them, they did sound great.)
Hence - with the combo of 1 & 2, I would probably upgrade the amp first.
I assume that the OP is using the 4 ohm tap?
They may also benefit from a set of KT120s if they wanted to keep the PL amp.
Maybe that would allow them to punch a bit harder?
