Help choosing a DSP processor for an all analog 2 channel system. MiniDSP 2x4HD is not my taste.

If you do not need a dsp crossover (not including subwoofers) you could look at the Emotiva A/V signal processors -

Basic -

BasX MC1 13.2 Channel Dolby Atmos® & DTS:X™ Cinema Processor

High End -

RMC-1 16 Channel Dolby Atmos & DTS:X Cinema Processor

Please note that in my system I use a minidsp openDRC-DA8 (no longer available) with coax spdif stereo input for stereo tri-amplified speakers -

Hello, I am reluctantly considering a DSP processor for my system that is composed of a TechDas AFIII premium, Manly Lab Steelhead, Pathos Heritage, Tannoy Canterbury and 2 REL #25. I can't add more treatment and I am still having lots of dips and peaks in the 180-230Hz>15Hz.
the intention is to manage the 2 REL #25s, so they can be play in phase; and if the DSP processors is really good, I would be willing to get the speakers there too.
A colleague of mine and I spent a lot of time trying to make the MiniDSP 2x4HD sound good and we measured with REW for an entire afternoon, but I rather not have DSP that the sound coming out the MiniDSP because in my ears the MiniDsp robed all the magic on my system. Is there a better option?
Thank you!
To implement DSP to your system it is few must do. Nr.1 convert system to active could be a picture will be more illustrative. Nr.2 By pass all passive filters in a speakers. This picture illustrates my stereo system.

Nr 3.Learn how to use DSP
Money not always is the way out of bad sounding sound system.What you hear depends on age too and that is the other thing what money can`t buy - a youth.

In looking at the specs for the Pathos Heritage I see that while there is a line level pre-out there is no line level pre-in (what us old timers would call a tape loop). In order to use a signal processor with your amp (be able to use the power amplification stage) you would need an independent input to go along with the pre-output. You can only use one line level input at a time so if you use that for the signal processor you can't listen to your turntable. Also considering the frequency range of the dips and peaks the problem is due to room resonances. The signal processor will only correct that situation at one location (where you sit). I would suggest that you get a good dsp preamp and only use the Pathos Heritage as a power amplifier. You might want to look at the Emotiva signal processors (between analog source and Pathos Heritage only being used as a power amplifier) unless you really want to bi-amplify you current Tannory speaker which would not help with the room resonances.

After looking at the articles on you Tannoy speakers and your subwoofers I would ask how your bi-amplifying the subwoofers with the Tannoy's. What is the crossover frequency and what are the crossover filter functions? How does the system sound if you just use the Tannoy's as full range speakers?

@brombo I am not bi-amplifying. The REL are connected to my speaker taps and they have their own amplifier.

Have considered a good two channel dac (Emotiva Big Ego + or fancier) and Jriver software on you computer? The problem there would be analog inputs. If you can find one look at (using your computer again) a ASUS essence stx ii. It has a good DAC (with pluggable output OPAMPS) and ADC so you could input your your analog sources (more than one would require an external switch). Two years ago I got a ASUS essence stx ii 7.1 (stx ii with daughter card) for $330. Current price on Amazon for essence stx ii is $340.

Since you already have a Steelhead, have you looked at the Manley Massive Passive EQ line???
