Long-time lurker, first time poster.
I thought I would share my experience with the lyngdorf tdai-1120. My previous setup was a Rega elex-r amp with kef ls50 speakers and SVS SB-12 NSD fed by a bluesound node 2 streamer via a chord 2qute. I had steadily built up the system and generally very happy with sound and reliability for streaming Tidal files - I have long since given up on buggy Spotify connect and pi based streamers. However, I felt at times the sound was a bit soupy due to the speakers running at full range alongside a sub and very unfriendly room dynamics (kitchen diner with almost entirely hard surfaces and speakers mounted in top corners safely away from toddler hands).
I came across room EQ in a blog post by Darko, which piqued my interest about neutralising my room and boosting performance. Initially I looked at Dirac through DSPmini 2x4hd and adding another seperate but dismissed on the grounds of cost once customs duties and the seperate mic are factored in, and wariness of techhy audio kit with limited user support - the Allo Digione streamer experience scarred me. Furthermore, with glowing reviews of moderately priced all-in-one boxes with room correction such as arcam sa30, Nad M10 and lyngdorf tdai-1120, it seemed I could gain room eq and crossover, maintain performance and be cost neutral once selling my old kit. An open-box deal on the lyngdorf swayed it as I figured I could sell if it didn't work out with taking too much pain. After an hour of setup with room perfect, a side by side comparison using tidal followed and I was immediately struck by the general openess and cohesiveness of the sound from the lyngdorf compared to the seperates. Flicking the roomperfect on/off showed this was due to more than just the crossover. I should have stopped my analysis here and been happy. Instead I thought I should see how the bluesound streamer and chord DAC into the lyngdorf analog input sounded and it was absolutely stunning - a new hi for my hifi for sure. Crisp highs, round lively base, good timing and great soundstage. I have now decided that with the kef ls50s, assuming room perfect was effective, the lyngdorf is quite harsh and somewhat tinny in the treble. I played around with the relaxed and soft voicings to tame this but there is just a persistent harsh flatness in the upper range that I don't like. If I am missing something in the lyngdorf settings then do please let me know.
In summary, I am super pleased with the lyngdorf + external chord DAC + bluesound and would wholeheartedly recommend something similar to anyone considering it but I would struggle to get behind the lyngdorf alone based on my experience. Sadly, I now have a big hole my cost neutral budget as I would struggle to go back to either the seperates or the lyngdorf alone. I may see if a CCA can replace the bluesound without impacting performance too much and claw back a few pounds.
