@yyzsantabarbara those two amps must be great with the LRS+. In a natural and logic way I am trying to work with the 5 amps that I have available before any thoughts on anything else. The Coda and Sanders are not only very interesting but also expensive and unavailable in Europe.
I bought the LRS+ sure that the Vincent SV-237MK (that drives everything) would pair well with them… and it is ok but there is that treble level issue.
My second choice was the Rogue Sphinx, referred by some as a good match… but there was that treble again, irritating high.
It was not about treble quality (I saw that could obviously improve with burn-in) but it was the high level, something that I perceived to be within the speakers character.
At that point (with more or less 100 hours) I could:
1 - try the resistors, although not the stock ones, spending 50 euros.
2 - buy another amp, spending at least 750 euros on a used power amp.
The first choice was an easy one :)
Now, after about 250 hours, with the 1,5 Ohm Mundorf resistors that did reduced effectively the treble level and didn’t affect the sound quality, is natural that my questions are about the resistors, to learn from other’s experiences and to see if I can get even better results.
