Dumping it all for Lyngdorf???

Lyngdorf lover here. I have a TDAI-3400. Speakers are Spatial Audio X5. I also have a Whammerdyne DGA-1 (SET amp) and an MSB Analog DAC, which goes against the OP's goal of simplifying, but I can toggle between which source system drives the speakers. The Lyngdorf sounds so good that I listen to it 90% of the time and only switch to the Whammer/MSB setup when I want to sit, focus and really dig deep into the experience. In that case, the Whammer/MSB does create more space and dynamics, but the Lyngdorf is VERY good. And its room correction and DSP capabilities are fantastic.

Well... don't know about Lyngdorf... but... I do have the Hegel H590 integrated (DAC, Pre, Amp) in 1 box.  Use the Bryston BDP-3 as the player / streamer - which is superb also.  This setup drives my Harbeths to perfection - which few others can.  

It is much more simple than everything in separate boxes, which you must get just right to do the job as well.  And you eliminate a lot of the "cable" questions.  

So... I'm sure the Lyngdorf might be "just the ticket" for some speakers - though, it would have to match their requirements to drive them to their best.  

@rbrertalotto- it’s good to save up for things, but from where I sit, everything I want to buy jumps $500 every time I turn around.  Maybe better to buy on credit and pay a few months interest. Just sayin. Also, if the 8 watt tube amp is what you love, I doubt any moderately-priced solid state amp will make you as happy. Just get the sub and be done before the price doubles. IMO. 

I bought a Lyngdorf 2170 for my downstairs system.  My living room is not a good sounding room, and the Lyngdorf Room Perfect correction really made a huge difference in a problematic room.  If you don't have a well treated dedicated room, Room Perfect can be a game changer.  My Lyngdorf displaced a very highly regarded 300B amp.  I thought so highly of it that I encouraged two of my adult children, who are budding audiophiles in their own right, to go the Lyngdorf 2170 route.  They are both well pleased with Lyngdorf.  If you are running a digital source, inputing the digital signal to the Lyngdorf is astonishingly good.  This digital from beginning to end thing that Lyngdorf advocates is the real deal.  I am somewhat less enthusiastic about running analog in.  My daughter wanted vinyl, and we had to get her a phono preamp.  The built in phono on the Lyngdorf was just not very good. 

I bought my Lyngdorf used.  That kind of money for a superb integrated amp with an outstanding Internal DAC is just crazy cheap.  Highly recommended. 

I have the LS50 Meta’s set up with the KEF KC62 sub and am using the Arcam SA30 integrated amp with built-in streaming. This $3300 amp has sound which is rich and pure. The overall system is knockout, not even considering the low price.
