Good Suggestions for Tube Amps under 6k

From PL website:

PrimaLuna uses ceramic tube sockets secured to ventilated steel plates that are bolted to the chassis. The entire signal path, including resistors and capacitors, is painstakingly hand-wired with heavy gauge cable by craftspeople. In our EVO 300 and 400 models, we even use Swiss-made silver-plated oxygen-free copper cable with a Teflon dielectric in the entire signal path. The result is a product that sounds amazing and lasts for decades.

You need to up the price if you want to best the PrimaLuna. I own that amp. I’m super surprised when someone wants to sell. It’s the only thing I never think of changing out.

Luxman mq88 is built like a work of art reliable as a stone and sonically wonderful.

It's going to depend a lot on the kind of sound you prefer. I have owned several of the amps suggested here by others and liked things about each one, but they are also all different.

My favorite by far in the upper end of your range (and well beyond) is the Synthesis A100 or its little brother, the A40. Both of these units also have an excellent onboard DAC, although you could try it compared to your Lampizator to determine your preference.

While the Synthesis amps do not seem to get as much attention in the forum as others, those who do have them seem to love them as much as I love mine. I highly recommend adding it to the list of amps you are considering.

Daedalus has been pairing with LTA at audio shows for several years now so it 's a natural match. I quite liked their Z10 integrated last time I heard it at CAF. As usual @charles1dad has some excellent suggestions the AN Oto in particular is a sweet little integrated.
