Dumping it all for Lyngdorf???

I think the Kef require power to make them perform to their capability which is the trick in this equation.

Recently I'm driving them with an 8 w/ch tube amplifier and loving it! Usually I'm running them with 50 w/vh Pass Labs First Watt....

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.
