Upgrade to McIntosh

There are many better quality products then McIntosh.

I used to sell them before they sold out to a Asian company 

and some of their products now made in China which is sad .

nice looking meters though . It’s whst inside for parts quality that count most .

for a tube amp Ayon is much better in every respect ,the transformers and chokes 

are the heart of any good tube setup Ayonuse world class Lundahl 

McIntosh nothing special . And inside Ayon uses Mundorf ,Mc maybe wima still.

Ayon machined cases , this is one very good example  sadly McIntosh  is way overpriced for what they provide do your homework. The mc275 is very respectable 

but there are much better out there I just mentioned a few items .

Trust your ears. 
 

If you like it - that’s what matters. I’ve owned a C2600 and MC 302 with Sonus faber Olympica Nova Vs. 
 

Mc stuff has a strong secondary market. 

If you’re unsure experiment - Rogue makes some excellent hybrid and tube stuff for a great value  

I love the MC275 it’s a workhorse and a tank! I wouldn’t pair it with a Mac pre however as the sound is on the dark side I much prefer a CJ like a ET5 is a steal used for the $ and hard to beat. Also tho are you doing the MC275 because it will be on almost all the time or ? As way better soundstage with a CJ amp also but not made to run 8days a week like the MAC. I’m closing do separates but not mono blocks imho I’m very happy with my VTLS200 (another versatile well priced used amp🌟 but if you have efficient speakers and love the MC275 go with it my Uncle loves his and I do to for what it does it’s truly a gem

Ayon IS great stuff, but not always easy to find or contend with receiving those beasts on a pallet.  I too have an MA12000, but find it more than awesome in my setup.  Both units are beautiful in their own way and a joy to be around.

Even the McIntosh SS amps are warm sounding. If I ever go back to tubes, it will be only in the preamp section, I never got tight bass with tubes.

Check out the new McIntosh gear, they are hybrids with tubes for midrange/tweeter and large SS for woofers in 1 chassis. 
As for a built in dac, these are always a compromise over a separate dac. I used to have the McIntosh c47 preamp with phono and dac. I played this dac for 5 minutes and never went back to it, my standalone psa ds sr dac sounded much better.
