Perlisten—Boulder—D'Agostino

Based on the one time I heard those speakers, I would choose whichever amp sounds warmer. I heard the Perlisten S7T speakers in a treated room with a D'ag Momentum integrated and it was too bright and bass-shy for me but maybe that sound was because of the room.

I compared dag progression to Boulder 1110/1160/1161 about a year and a half ago using Wilson Alexia’s. The dag was warmer to my ears the Boulder more detailed with greater clarity. On the Alexia’s there was a big difference between the 1160 and 1161; the latter sounding a bit thin. Haven’t heard Perlisten speakers at all so no idea how they will interact with those.

With an efficiency rating of 92.2 I chose a great deal on a NIB 1161 over the 1160. I have several people who say the pairing is excellent. Amp arrives tomorrow and dealer delivers and sets up the speakers on Saturday. Thanks for the input.

To my mind (and ears) the watts (sensitivity) matter far less than the current (speaker impedance/phase). I suspect why the difference between the 1160 and 1161 is so stark on the Alexia is that they have a big impedance drop in the midbass, to around 2.5 ohms, along with a steep phase angle. That makes them very current hungry if you want good controlled bass. And that was the big delta, the 1161 sounded thin whereas the 1160, with it's much larger power reserves, did not.

If your speaker doesn't have that problem then the 1161 could easily be enough. Which is a good thing because 1) the 1161 is a lot cheaper and 2) it's something that can be moved around by a single person whereas the 1160 is not.

Looking at the measurements of your speaker it does have some impedance drops combined with high phase, so it could get well get current hungry. On the other hand it's 3db more sensitive than my Alexia 2's, so it will be pulling a lot less power at the same SPL. How much you will miss the extra reserves of the 1160 will probably depend on how loud you listen.

This is a strange field: Heard the top Perlisten (Hegel gear) and they were the most rolled off and lfat sounding thing I have evr heard. Nothing above 3-4KHz subjectively. DOA. The dealership owner did not disagree.
