Considering equipment upgrade. Any advice?

You can do better. What's your budget?

Hi Russ, the 400 to 500 dollar range.  The features I need for sure are bluetooth and phono pre-amp.  

I’d strongly consider the Cambridge offering for that price. 

Hi Russ, the 400 to 500 dollar range.

Sorry not trying to be a snob but I don't shop in that category, so I'm no help. 

My advice is no receivers. The Denon has so much crammed in there it might as well be a receiver. Basically what you want to get the most SQ for your audiophile dollar is an integrated amp. But you kind of have to decide what are your priorities. The Denon has a phono stage, but who knows how good compared to what you have now? Likewise FM, you may get better sound overall with the Denon using the HK as a tuner. 

Also in a small home office situation do you really need 70W? You may want to consider a budget tube amp like the Reisong. 

Thank You all for the advice, your advice did not fall on deaf ears.  However , i found an open box deal on the Denon (under 300) so I picked it up. But the plan is to use the HK as my main receiver, which sounds great to me but has been a constant struggle because of the hard to get 7355 power tubes (I have had bad luck with expensive "NOS" tube availability and service life once i have found them).  The spot the Denon will play is to be the receiver while I'm servicing the HK with a possible secondary duty as a bluetooth source for the HK.  As soon as I get the Denon in place, I'm going to rework the HK amp circuits so I can change out the hard to get power tubes.   btw, I never liked the thin-bright sound of the DH-100/BB275 combo so even a sideways move there is welcome.
