Many hours of switching out connections back and forth and level matching later...
Current set-up: Schiit Aegir class-a biasing amp / Schiit Modi Multibit DAC / Schiit Saga+ Pre / Allo Digione Sig streamer. Sounds smooth, organic, beautifully engaging. Can listen to for hours.
Hegel H120 - Immediately cleaner sound, super clear. But after a while noticed my shoulders a little tensed. Just couldn't relax into it. Switched to the external Schiit DAC and A-B'd. The Hegel's internal AKM DAC was adding a significantly crisper leading edge. Not a subtle difference. Some people might like it. But for endless hours of music listening, nah. Not for me. The amp itself was decent if a bit sterile. Probably a bit overpriced at £2,400? Though if you've got pig of a speaker to drive then I can see why a Hegel might be a good option (Dynaudio/Kef folk seem to love the pairing). But yeah, no. Hegel Schmegel.
Lyngdorf TDAI-1120 - Tested the amp without Roomperfect. Not bad. Not bad at all. While it came across fairly neutral it wasn't as sterile/boring as the Hegel. It was super engaging. And zero listening fatigue. Plenty of goosebump inducing moments, zero fatigue, tight bass, solid mids, smooth treble, excellent sound staging. It's a great little bit of kit... the streaming set-up, the voicings, EQ options etc. And it doesn't cook eggs. I also tried it as a pre-amp into the Schiit Aegir and A/B'd. That smooth, organic'ness was back. If I hadn't already heard the Aegir I'd have probably been totally happy with Lyngdorf. But the Aegir can't be unheard, just a richer more organic midrange lushness. Bugger. Tinkering with RoomPerfect; initial impressions significantly cleans up room bass bloat that I didn't know existed. Still testing/figuring RoomPerfect out, could be a deciding factor.
So the Lyngdorf / Aegir was the very best combo but doesn't solve the initial problem of heat and puts me £2k out of pocket lol.
Pondering whether I'll be happy with just the Lyngdorf... love, love, love the simplicity of it and getting shot of 326 metres of cables. But would I miss that midrange? I dunno.
Also spent way too many hours researching all your amp suggestions (thanks) and the one I'd most like to hear is the Exposure, sounds right up my street. "Sweet", "Creamy", "punches well above price" etc.
Options I'm considering...
1. Stick with the Lyngdorf and have an easy life (might add a small sub as Lyngdorf sub integration is supposed to be world class)
2. Lyngdorf as pre/streamer/room correction + Exposure 3150 power amp (£1.5k)
3. Exposure 3150 integrated with external DAC streamer (quite like the look of the Zen gear, neat and tidy and good value)
Argghhh. This hobby. Someone tell me the answer please?
