Digital integrated alternatives to SET tube system

I have the Danish built Gato Audio 400-S integrated amp And could not be happier 
it is not only a work of art  to look at it is custom throughout nothing off the shelf, including a very respectable Burr Brown Dac.
tons of power on demand with a active line stage. All new units will be internet ready 300wpc -8ohms  roughly $6500. A lot to offer for the money.it sure has a bit of Tube character warmth as well as very good image depth ,and soundstage width.

I ran a set of Harbeth 40.1s with a Devialet 120 and Lyngdorf 2170 in the same room/system side by side for a couple of weeks. It was really no contest for my rig and room. The Lyngdorf was really considerably better. The real difference maker was and remains the Room Perfect room correction Lyngdorf employs. The 2170 lifted the performance of the Harbeth speakers to another level top to bottom.

This was my experience in a dedicated music room with substantial acoustic room treatments.

I later paired the Lyngdorf with speakers ranging from the effecient Living Voice OBX RW, AZ Crescendo, Tekton Double Impacts highly modified and the Dali Epicon 6s. The Lyngdorf paired wonderfully with each speaker and still remains in my system.

Uncanny way of playing equally well at low and loud volume levels. Amazing how much noise is in our music that goes unnoticed until one uses a unit like the Lyngdorf 2170 or 3400. Lyngdorf’s SOTA room correction brought out the very best of each speaker in my listening spaces.

I tried using the 2170 as a preamp/room correction device only with several tube amps, but each time the 2170 sounded better on its own. Keep in mind this is my subjective experience and preference. However, I love tube amps and preamps having owned and enjoyed all manner of them over the decades. OTLs, SETs, PP and SEPs. I find the 2170 with room correction optimized just sounds like music.....not like tubes, not like SS, not like Class D, not like Class A.........just enjoyable.

@audioman58 That is a gorgeous amp, I'd take the Walnut!  Thank you. More food for thought.

@grannyring Thanks Granny. I've followed along on your 2170 comments and your DI mods as well.  Great to have some comparison with higher efficiency speakers.  Really like the fact it can maintain composure at the lower volumes.

Thanks I have  the walnut. I bought the show demo and got a nice price.
if you  did want one you could probably buy direct and get a good deal.
best of luck in your search .
