Why don't Preamps (with built in Dacs) have HDMI inputs?

I guess I am describing a 2 channel Receiver, but I cannot think of many out there in the market save for this one.

Wouldnt it add tons of utility to products like the Stealth DC-1, or the PT-100 to have at least a single HDMI in/out so that you can get your SPDIF information directly from the source instead of having to use an audio extractor or your TV's optical out. 

I ask because I know that TVs are not built to audiophile quality and their digital outputs can have lots of jitter. I used to think this was rubbish until I tried using a digital reclocker (https://ifi-audio.com/products/spdif-ipurifier), with my TV's optical jack and noticed a significant improvement in the sound. 

Is it very expensive to add HDMI inputs to products or is the demand just not there?

Adding HDMI is expensive, and not many users have need of it as an audio-only solution.

Absolutely true. The compliances and the cost to join "The Club" is not cheap. Also to just pass audio makes no sense, so it would most likely pass video as well. I don't really see a problem with this, but we have a couple solutions with HDMI. AVRs and Pre Pros that do the job just fine.

The Onkyo TX-8270 receiver has HDMI inputs. I owned one for about a year. Good receiver for the $400 I paid for it. It has internal crossovers so integrating one with a sub or two is easy. Integra markets the same receiver under their mark. Pioneer has one, probably a clone of the Onkyo/Integra model since all are owned by Onkyo now. Arcam or Anthem, can't recall for sure, also has a stereo receiver with HDMI inputs. Great stuff for anyone not needing more than 2.1.
