Entry Level Tube Integrated

Primaluna used is a good deal.

I will second the Decware but have efficient speakers 92db plus unless you get the Torii.

There is one out the a mkI for around 1100.00 but most of there other models need efficient speakers i run a mini torii at 4 watts with some Ref 3A de capos

your focals are 92db but may not be an easily driven with a low watt amp

also look at Vista Audio i had a great 10 wpc EL84 amp of theirs great value used

Some of the more powerful Jolida integrateds could allow more options, and are still a bargain. I'd get whatever 502 integrated is around since I enjoy my 502p so much, and it has plenty of power.

u might want to look at some of the great vintage tube receivers. I was floored when listening to a vintage Scott system using only 35watts going into a pair of vintage sound dynamics 300t speakers. Easy on the pocket and fabulous on the ears. Just a thought. Good luck.

your speakers will not benefit from tube amplification due to unstable impedance.
plan to get easy driven speakers as for your secondary system along with entry level tube amp.
my choice would be vintage hh scott stereomaster 222c that uses EL84 power tubes and self-biased. so far it's the sweetest tube amp i've ever heard for less than $500 fully serviced and restored no snit! you can continue going vintage street for your speakers as well. 50's...60's models vintage having 8ohm or higher impedance are certainly the best match for your future amp.
you can also get vtl tube amp that is stable to 2ohm, but many of them having reliability issues and short tube life not suitable for entry-level tubes at all by all means.

Go with the Cayin line, better sound, value and service. I have many of their units and have never been disappointed.
