Mid-fi integrated tube amp advice

I've recently upgraded my 35 year old speakers and turntable to kef q900's and a dc carbon table with an ortofon red. 

I'm still running a 35 year old, mid market denon av amp butt have been looking at ss and tube amps with a budget around $1,000.

This just became available locally and I think I can get it for a bit less.

There's not a lot of info on it. Does anyone know of the amp that can give an opinion. I'm also very open to other suggestions.

Cage is just to keep little fingers from hot tubes...Don't know about the locite plates...Standby mode does keep a certain part of the small signal tubes hot,should still last 3500+hours...

After a month of listening, I finally got around to checking the bias. It's .25-26 across all 4 tubes, considerably lower than the .37-38 I've seen recommended and the .43 printed on the amp. I'm wondering if Tabnac dialed it down for break in. I've got about 50 hours on the amp and think I need to just bring the voltage up to spec.

Any thoughts on the benefits of lower voltage during break in?

Saves a tiny bit of tube life but IMO gives up tone as the tubes aren't operating in their sweet spot...
Probably like that from the factory,I don't think either of them run them in & bias them..
By the way I was cleaning out storage & found the Matched Octet of Mullard made for RTK small signal tubes I used on mine.When your ready to roll them give me  a shout,I'll give you a good deal...
