harman kardon has few stereo receivers. Two of them also have digital inputs.
sherwood also has a cheap stereo receiver available.
HK has had some issues lately around handshaking with HDMI. So I would wait or go with another brand though they are updating the AVRs with fixes often. still some issues remaining that they need to fix.
Yamaha, Pio or Denon are good. Also integrateds are a good choice such as the NAD series as the older models are being phased out.
most here find that integrated amplifiers sound better than steroe recievers including myslef
However the recievers also offer a tuner and some also offer a video input and output ( i think the HK does)
this makes switching between the sources easier.
Go and listen to a recievr and an integrated amp. Judge the difference yourself.
if you dont find much your options will be open and you can buy a comparitevely chaper reciever vis a vis and int amp
budget recievers are
Yamaha rx 397, 497 etc
marantz Sr 401 or sr 4001
if you gonna spend more than 16-17k on the receiver it makes sense to buy a 22-25k entry level integrated instead
