I have had my Monolith HTP-1 for about a month now to upgrade from 7.1 to 7.1.4. It is an incredible value. The processor is very well conceived and the bespoke setup options at this point seem to be endless. Easy to learn, lifetime to master. Ok, probably not a lifetime. It was up and running in a couple of hours, but I think it will take a couple of months to get it EXACTLY how I want it. The expandability to 16 channels is outstanding. The sound is superb in both 2 channel and 7.1.4, very transparent. I thought the setup using a tablet would be a problem, but I now prefer that to on screen. My wish list for future versions would include 12v triggers programmable to each source and momentary on screen volume feedback.

I would not hesitate to recommend the Monolith HTP-1 to anyone.

Excellent pre-pro with seamless Dirac integration. Updates are easy to achieve over the internet. The sound is transparent and the various sound modes work very well. One thing of note: you need a microphone that you provide for the measurments. I have found Minidsp’s Umik-1 to work perfectly.

The HTP1 is a noteworthy product in several ways, but for me it was a product that offered Dirac room correction with sophisticated bass control. Other considerations were channels for more speakers/multiple subs and functional eARC. It was encouraging to see generally positive feedback on Internet forums. And quite interesting to see Monoprice participation in some, to point of adding features (e.g. flexible signal generation to use with measurement SW).

The HTP1 is a quality all digital audio product that can switch/pass 60hz 4K video sources. With 16 channels it can handle a variety of speaker arrangements and/or handle multiple subwoofers with state of the art Direct Live Bass Control. I'm very happy to say I bought one.

I have had multiple surround processors in my system over the years. Those include two Lexicons starting with the MC-1, the Anthem D2, the Marantz AV8802A and now the Monoprice HTP-1. I think the Dirac is much better than the ARC or Audyssey room correction systems. The sound is noticeably more clean than with the Marantz w/Audyssey. The overhead speakers have come alive with the HTP-1 w/Dirac. Movies sound great, but 2-channel music is better than ever. Stereo music is focused with a better defined image than ever before. The only negative is the remote; the buttons are too small and close together. I know that it is easier to use the web interface, but I like to grab the remote.

It was challenging to go thru all of the brands and models available in selecting a new AVR/AVP. I was a long time Yamaha owner and felt that selecting a Monoprice was a little out of my comfort zone. But, wow and I pleased. The HTP-1 is the most user friendly AVP I have ever used or seen. It is very sophisicated in its technology and all of it works as designed. I could not believe how easy it was to navigate, setup, and feel comfortable with a new piece of equipment such as this.
Thank you Monoprice!

I have had my HTP-1 for a little over a month now and man do I love this processor. With all the stories about the other 9.1.6 processors out there and how buggy they are, this one just works. It sounds great and I really like the web setup interface.

I've owned many processors and receivers and this one is the best yet even compared to ones that are double the price. Stable HDMI, stable CEC, great audio, easy to use if you know what you're doing, Dirac Live is incredible. Buy it if you have the Home Theater for it.

1. This device works. It's amazing that it's so new and is so mature. Connect your devices, your amps, plug it in, and it's ready to go.

2. The basics all worked correctly without tweaking. CEC, eARC, HDMI switching, Dolby Vision, HDR, HLG HDR. It was nice to see HDMI input changes in 3 seconds versus 15 seconds on the other unit.

3. Dirac 2 is very nice. I did a quick calibration with just one "sweet spot" recording, and it really sounds great. I kept telling my wife that I really haven't even started to dial it in yet.

4. We put on an Eagles concert that we knew well. We both thought audio was improved - examples - acoustic guitars seemed to exhibit more of the sound you'd hear if you were at a concert (more detail). The bass was clearer too..

5. I absolutely love the LCD information screen. It looks VERY high end to me. It's also clearly visible 12' away.

6. I can actually control the volume using my DirecTV remotes due to CEC working.

7. The remote was a little underwhelming - no backlight made it really tough to use. BUT - you can use your smartphone/tablet to control stuff, so it's really not a big deal. I may get a Harmony just to run the HTP-1 (I'm not a big Logitec fanboy).

8. It's a Roon endpoint. Not certified yet, but it works out of the box. To be honest, l loved seeing the Roon logo on the LCD display.

9 Software updates come via the internet.

10. Updating things like HDMI input names is extremely easy and very fast. The browser-based configuration/control is wonderful (needs a little tweaking, but it's 90% of the way there, compared to the other company that had 0% browser-based config.

11. There's no on-screen GUI. This worried me until I tried it. The LCD screen makes it totally unnecessary.

12. Did I mention that HDMI and resolution switching is VERY fast and handshakes were 100% successful the first time (there was no screen for .5 seconds, darkness for 8 seconds, and a resumption of screen we have with the other company)

13. Size - front to back, it's shorter than the other unit. This surprised me, but it sure made fitting it into my Standout Designs furniture a lot easier. I think it's probably 5 pounds lighter too. (Makes sense - electronics keep getting smaller over time)

I'm very, very pleased with my purchase, and give the folks at Monoprice and ATI a solid "A" grade. "A+" is coming after the USB input is activated.

Lastly - my wife said, "When can we get the ceiling speakers?" because she was so impressed. This machine has a very high Spousal Acceptance Factor, which means a lot to us married folk

Was looking for a next generation cinema processor with 16ch and Dirac calibration. The HTP-1 is everything I was looking for and more. The processor features list is great, sound quality is top notch and the Ethernet update is easy and very convenient. On top of that the HTP-1 is a very solid processor in term of reliability. HDMI and sound lock is rock solid. The developer team seem pretty fast and responsive with bugs corrections and firmwares are quick to release. I really like the web setup interface. its easier to use than expected. You just enter the ip address that appear on the processor screen in any device (iphone, ipad or pc) and you can fully control and configure the HTP-1 from the web page. Ultra fast, powerfull and ultra easy config. I really like the fact that the HTP-1 is compatible with eARC. Not all processor have eARC and it allow me to send my Sony Oled TV internal apps Dolby Atmos sound track to the HTP-1. The only thing I am missing is an internal test tone generator. Not a deal breaker since I can use any test tone from a Dolby file but it will be way more convenient to use an internal one. The processor is still young and maybe they will add this features with a future firmware update. Talking about future company representatives already say that they planning a DTS-X Pro upgrade, HDMI 2.1 upgrade (with fee) and Dirac bass management. I hope they will also add Imax Enhanced down the road. Thanks Monoprice for this great processor. Not cheap but I think I will be able to keep this one for a long time and make it a well worth long terme investment.
