My listening room has serious issues. I've discussed it in length many times so I won't bother repeating it again. I can't begin to tell you the number of amps, integrated amps, DAC's and loudspeaker combinations I've tried in that room over the past three years to try and get SOMETHING I could listen to for more than a few albums before turning it off in complete frustration. My GIK room treatments helped tremendously, but every time I cranked the music up above a certain volume everything fell apart and I got extreme
listener fatigue. My last integrated amp was a Lyngdorf Audio TDAI-2170. It was a very special sounding integrated amp with built-in room correction that NEARLY got me to my special place, but in the end my shitty room won again. If you have a "normal" rectangular listening room it would probably be the perfect "all-in-one" Amp/DAC/room correction device.
I can't begin to tell you the number of hours I put into finding this combination, but I have finally found sonic nirvana with the following: Spatial Audio X2's with a Primaluna DiaLogue Premium HP integrated amplifier (stock tubes) and a Schiit Yggdrasil DAC. All cables are Cardas Parsec except for one digital cable from Pangea Audio (Audio Advisor) that uses Cardas Grade One Copper. I'm one week into this combination and I can't stop
listening to music. I've played at least 30 albums from start to finish and every one sounds better than I've ever heard them before. Music just floats around the room. On really great recordings - like electronic music on the !K7 label - shit is just everywhere! Front, back, top-to-bottom, and everything extends way
beyond the speakers. The first and only album by Peace Orchestra is SCARY good! Box speakers used to completely rattle my room when the bass hit a certain frequency, but not with the X2's in this system. Bass is deep and powerful without the nasty side effects.
The Lumina L2's keep me wondering how much better it can be, but for now... I'm there.
