Recommendation Tube Integrated

Depends a bit on your room. Saw someone recommend a Leben 600 but for the right space the little Leben 300 is absolute magic. Well in your budget and you could build quite a system around it. 

Ayon has the best build quality and transformers, chokes which is the heart 

of any tube gear which they use world class Lundahl.

and the only brand I know that uses a microprocessor to monitor and adjust each power tube , plus a machined Aluminum case not sheet metal like most ,

much lower vibration ,all tube sockets gold over Copper the best conductor 

for the tubes and well as connectors, Mundorf coupling capacitors .not much competition at its price point , which I have bought 3 of their products.

Luxman LX380 without hesitation.

I just picked up a Jadis DA50S. 30 Watts pure class A. I would have never believed an amp in the $10k range could perform this well until I heard this thing in my home.

FWIW I am currently auditioning the Lamizator Poseidon with it. Fantastic combo.

Octave Audio, V40 SE - upgrade the tubes w/HQ NOS 12ax7 & 6922 and pick your poison for KT88, KT90 or 6550. Amazing integrated and can sneak it all in with tube upgrade for about $6K. Toss in a Black Box offboard power supply for another $1500 and drop the mic, you’re done!
