This is the Denon PMA-600NE integrated stereo Amp’. It has exactly the power output I have been looking for, 45 Watts per channel into 8 Ohms. This is ideal for my Wharfedale W45’s. This Denon has the all of the goodies. MM phone input. Optical, and coaxial digital inputs. An LFE output. Bluetooth, and the expected analog inputs. $399 USD

If I could get an Amp like this with an ethernet connection to the internet, on screen, and a set of HDMI ports. Plus the usual inputs digital and analog. My Yamaha has all of that but what I don’t need is the tuner, I have never used it the antennas are not even connected.

Built in DAC and remote control. If only you could make it look vintage to match the Wharfedale W45's.

There is that, but there is an other amp I am looking that does match that vintage look. It also has 40 watts.X 2 it just doesn’t have all of the modern bells and whistles. It is a 6CA7 (EL34) base tube amp. According to the reviews tweaking the bias, and replacing the EL34’s can improve it’s sound I happen to have a whole box full of unused new Telefunken EL34’s with gold pins in the tube stash.

Always been intrigued by Yaqin's...as long as the iron and copper are there in the transformers which has always been a question mark for me. Not sure I would use any valuable or vintage tubes in a Yaq. They are reputed to run them quite hard which means shortened tube life. This was the word on the street a few years ago. Maybe they have improved.
 
I haven't looked at Chinese tube amps in a while. Have a look at Ming Da. I wish they wouldn't put a cover in the transformers, just don't trust them enough not to skimp on iron and copper.

That is why you tweak up the biasing. The Youtube videos indicate the biasing is set at around 42 MV, the EL-34 works better at about 32-36 MV bias. My service bench is setup for vintage tube receivers and transmitters so this sort of adjustment is easy. . The old RCA, Sylvania, GE, Telefunken, Mullard tubes were built much better then most tubes produced in China, Russian tubes from Svetlana, and Sovtek are just about best tubes ever made.

In China one of the ways a person can show off their social status is with tube type amp’s. There you can find audiophile grade amplifiers with 811A’s, 572B’s, even 3-500Z tubes. The latter amp has a hide away separate power supply so the Amp itself be shown off. Here in the States there are a couple of outfits that make mono tube amp’s with the 3-500Z they cost around $70,000 bucks for the pair. The Chinese amp’s sell for around $2500 USD. I understand they are as good as anything out there, plus the Chinese graphite 3-500Z which normally is used in HF transmitters has an excellent sonic profile.

Was researching the YAQIN MC-13S and it has Japanese made silicon steel core transformers the windings use enamel insulation.

This is the review that got me going on the Denon. Steve Guttenberg is my favorite audiophile Youtube channel.
 
If you get the Yaqin, you're going to want a full function preamp to go with it. The Denon looks nice and has all the features + the price is right. Oh! and let's not forget the remote!
 
One of the interesting details on the Denon if it senses there is no digital inputs it automatically switches off the DAC to reduce noise.
