I didn’t read all the posts. I also have Dynaudio HS on the stand 20. My suggestion is a pair of REL subs. They will do much more than just add the bottom end. A pair of S/510 or S/812 would do it all. I have a single S/510 but my space is much smaller than yours. Oh and I think the the Octave Research might not have enough grunt for the HS. I use an Aestheix Mimas on mine it’s about double the amount of power the Octave has. Dynaudio’s really love power!
Floorstanding speaker experiences/recommendations in the $12-25k range
I realize there are thousands of options, but I'm looking for strong personal experiences/recommendations for floor-standing speakers in the $12-25k range. I currently have Dynaudio Heritage Special stand-mounts. They really are a great speaker in many ways, but full-range they are not. There's an obvious missing element to the music in the <45Hz range. I listen to 95% vinyl, 5% CD (I stream off a Bluesound very occasionally to get ideas for albums to purchase). My system is comprised of a Rega P10 with Hana umami red cart, Modwright PH150 reference phono stage, Oppo 205 disk player all into an Octave V80SE integrated amp with super black box.
My current "leaders" for speakers are Qln Prestige 5 and Devore Gibbon X based on what I've heard, but have liked the Wilson Sabrina Xs and have heard great things about the newer Borresen X3s. Any experiences/recommendations welcome.
Cheers!
