I am looking for a 'cleaner' solution to running a MiniDSP HTx + Schiit preamp, and this might fit the bill.

Can you turn off processing for analog inputs - so I don't have digital processing of analog from my turntable, for instance?

This is your best bet for latest and greatest info on HTP1. Many of the developers also hang here and are a great resource. And yes, I am a very happy HTP1 owner :)

 
Wow, finding the updated info was easy since it was just released a few days ago. Thank god!

Cross posting here from the above AVS thread:

____________________________________________________________

Version 2.0.8, Final Release Version 2.0
May, 2026

New Features
  • ART capable Dirac Live module replaces the previous Dirac Live BC (Bass Control) module
  • The post-Dirac trim and delay controls are locked when ART is active. This is a Dirac requirement.
  • What was previously the “custom” UI is now the default UI, with further development
  • The front panel code was rewritten to support touch features and network setup
  • A balance pane is added to the UI to allow for the adjustment of channel gains without affecting the exact speaker response matching required by ART
  • One of the outputs can be configured as a simple seat shaker
  • The PEQ module has been moved to operate upstream of the HTP-1 Bass Management block and Dirac’s ART and BC modules, hence preserving phase relationships of speaker outputs
  • PEQ can now be placed either “pre” (default) or “post” Dirac Live filter block in Calibration > Show Advanced Settings > Change PEQ Configuration or PEQ > Change PEQ Configuration
  • Added debug screen to front panel
  • Added Mix Out power-on volume setting to the Volume Setup page
  • Added all-pass, high-pass and low-pass filter options to the PEQ
  • Added slider controls for PEQ adjustments
  • Added a per-row reset button in the PEQ
  • Added single-channel and all-channel selection for the PEQ graphic curve
  • Added draggable handles to PEQ curve visualization for intuitive curve adjustment
  • Added PEQ channel adjustment linking
  • When PEQ channel linking is enabled, imported REW filters are applied to all linked channels
  • Added support for low-shelf and high-shelf filters to REW filter file import
  • Added a graphical curve display and interactive drag controls to Tone Control
  • Added an Auro High Sides toggle (OFF: mixes High Side to Rear Height/Tops; ON (default): mixes to Top Middles)
  • New Wide Synth algorithm
  • When set to brightness 0 or 1, the front panel will briefly illuminate in response to Volume and Dialog Enhance adjustments
  • At brightness settings off (0 or 1), the front panel remains lit during mute
  • Added a Factory Reset option on the System page
  • Added debug options to System page
  • Switching speaker layouts is now faster
  • Introduced a real-time loudness curve display that responds dynamically to volume and loudness calibration settings. When tone control is enabled, the combined curve is also visualized.
  • Added Vintage Custom, a fully adjustable loudness curve option
  • Added an optional graphic bars view for peak monitoring (available under Volume Setup > Show Advanced Settings and VU meter)
  • Added timezone settings to the System page
  • Added User Guide Addendum PDF
  • Added Front Panel Manual
Changes
  • Dirac Live ART/BC post-processing locks are now enforced in all scenarios (mandatory requirement by Dirac)
  • Updated the PEQ graphic curve lower frequency limit to 10Hz
  • Adjusted the minimum Y-scale value on the PEQ graphic curve
  • Updated RED (show debug screen), GREEN (show settings info), YELLOW (reload front panel), and BLUE (reset HDMI) remote button commands
  • Lipsync delay limit raised to 340ms
  • After upgrading from version 1.x, the speaker layout is reset to 2.0 to make it clear that the user must manually select their actual speaker configuration
  • The minimum limit for Tone Control > Bass Corner Frequency has been reduced to 20Hz
  • User delay and trim are now reset to zero when a Dirac Live filter is transferred from the Dirac Live app
  • Deselecting all filters in the Dirac Live app now also disables Dirac Live on the HTP-1
  • Deleting a filter slot within the Dirac Live app now also removes the associated trim and delay settings on the HTP-1
  • The Factory Reset option on the System page also removes all Dirac Live filters
  • Dialnorm for Dolby and DTS sources now default to off
  • Night mode resets to off after a restart
  • After a speaker layout change, the first filter slot is selected by default
Fixes
  • Fixed filter delete from Dirac Live app
  • Fixed front panel not showing default volume after sleep
  • Resolved issues in the macro code editor
  • Fixed Dialog Enhance volume behavior
  • Fixed an issue where Dirac Live incorrectly reported a low signal-to-noise ratio when the input was set to 44.1kHz
  • Fixed an issue with input PCM Detect Sensitivity
  • Fixed an issue where power on/off/toggle via HTTP GET was not working
  • Resolved a bug that prevented Bluetooth discovery
  • Made progress addressing an issue where audio playback may fail after the device has been in sleep mode for an extended period. DSP now refreshes upon entering sleep when Fast Start is enabled.
  • Fixed an issue where the FH channel was non-functional in FH/TM/TR configurations
  • Skipping playback on a source device no longer produces static noise
  • Fixed an issue where the Dirac Live filter response could intermittently be incorrect
  • Fixed an issue where the Dirac Live filter failed to load after changing speaker layouts
  • Fixed an issue affecting loudness frequency response above the loudness reference level
  • Fixed an issue where the power-on volume ignored user-defined Zero Point adjustments
  • Fixed an issue where muting and unmuting the main volume and Mix Out were not always properly linked
  • Resolved an issue in Volume Setup > Peak Monitoring where Sub 5 values were not displayed
  • Fixed an issue where log files could consume all available disk space
  • Fixed alignment, sizing, and appearance issues in the web UI layout
  • Various minor fixes and enhancements
Known Issues
  • Limited to 3 filter slots for the moment.
  • There are corner cases that can put the Dirac filter system into a confused state. This typically means that the filter is not being applied. This is indicated on the UI. See the User Guide Addendum for troubleshooting steps to address the case.
  • The wired network interface prefers to be on a 100BASE-T network. It’s known to fail to get an IP address by DHCP when it is booted cold on a gigabit network. Some folks configure their router to limit the port to 100Mbit/s.
  • Safari may fail to load the web UI. See User Guide Addendum for workarounds.
  • When playing Dolby or DTS content, the seat shaker output carries only bass from the LFE channel. With stereo or PCM sources, the output is a left/right mix, but it is routed through the Sub 1 Dirac Live filter, resulting in a significant change to the frequency response.
  • With Fast Boot enabled, the system needs a moment to clean up before sleep. If it never sleeps or powers down, the HTP-1 may go silent after a few days. This is a known issue. Putting it to sleep and waking it will fix it.
 
Again, the HTP1 developer crew on AVS have been incredible and made the HTP1 a poor man’s Storm/Trinnov/Lyngdorf! In many respects the HTP1 offers better performance than the megabuck offerings IMHO, including top notch analog performance. I was specifically looking for a prepro with a high level of analog performance (read output level and SINAD) that could perform as a dedicated 2ch preamp AND MCH/theater solution. Most prepros are a compromise for 2ch and as such many have two fully separate systems. I wanted to avoid this if possible. In the HTP1 I have found such a solution. I had a very expensive (and well measuring) dedicated preamp prior, the HTP1 has fully replaced it (and been sold, for more than I paid for the HTP1!)

Relevant specs are 16 balanced outputs, Auro, Dirac ART (add on purchase) with potential for PEQ preconditioning, loudness compensation.

God no. Why should vinyl sound like ass?

Though arguably digitizing your vinyl a step upstream instead of in the AVP makes sense. https://parksaudiollc.com/

I don't know about your vinyl setup, but mine is on my Carver AL-III ribbon speakers with a fully analog Carver C5 Sonic Holography preamp (connected to active crossovers and 350W per driver or 700W per channel) connected to a Lexicon DC-1 processor for surround and Logic 7 (the best 2-ch music upmixer ever made). I get +/- 2.5dB bass 26Hz-80Hz where the ribbons take over and a dipoke combined room response of +/- 5db (rated +/- 3dB anechoic) with zero digital room correction, only room treatments to the side walls (front/rear walls are active for dipole ambience, but rear wall is diffused.

It most certainly does not sound like "ass" in any sense of the word and it's a 100% analog path (as vinyl should be if you believe in analog superiority nonsense, which I don't, but it was easy to do on this system and it makes audiophiles drool. I recorded all my vinyl at 24/96 and ran it through Izotope RX for click and surface noise removal. But if someone wants to hear a fully analog Dark Side of the Moon off heavy 24g vinyl, I can accommodate them (recorded to digital on its first ever play and had zero clicks or pops without processing on that play).

I get better bass response in that room than my home theater room that does have Audyssey correction.

Now that there have been these ongoing firmware updates, I think Amir should re-test, and I think he would do so especially given the wide interest in the product. Anybody have an updated unit they would pull out of their system and send to Amir?
 
I got a used HTP-1 and I can’t see myself changing the setup any time soon. It is very very good.

My singular complaint is the remote is cheesy. I miss the monstrous blocks Yamaha used to make. Felt like you were controlling a serious piece of equipment.

That said, I keep a secondary web browser on my phone that opens up the web ui by default and it’s extremely functional.

Agree on the remote. I just use my phone with the web ui, works perfectly.

Have you measured it? Extremely few are the rooms that return good bass response without heavy treatment, and yet still DRC can still improve on.

Audyssey ≠ ART…

So WHAT!?!?!? ART ≠ Waveforming either. ART is experimental and requires surround speakers of deep bass to even function. How much do you want to spend? Trinnov Waveforming is the best.

ART is not experimental. It is actually gaining more and more traction as other manufacturers (except Sorm and D&M EDIT: and of course Monoprice) are implementing it. Mini DSP and Hyperion are about to ship, Arcam and Onkyo new lines are apparently going to be ART capable as well.

ART requires multiple sources of bass for best functioning. There is nothing to say that deep bass surrounds won't help, but then there is definitively no requirement for that. My surrounds going to F3 of 50hz don't do a thing until some 100hz.

Waweforming is what it is. But not really cost effective compared to ART.

BTW why so angry posts? Things get better sorted out with some chill.
