This is a dsp crossover based 3way system. The allo amp drives the compression drivers (for now). The custom O&B 6 channel amp drives two of the 15 inch woofers and subwoofers.. Minidsp flex 8 implements the crossover

The speakers look beautiful . I was following your build thread, and the idea of using the 6db boundary re-inforcement at the lower bass, was a very neat trick. I noted it down, for my future use

Coming to the crossover, is it loaded into the internal convolution engine of the Flex 8, or are you using it as only a multi-channel dac with the digital crossover done digitally in some software on a PC. Describing your crossover implementation either here, or in a separate thread will be very helpful for aspiring digital converts like myself.

I have been thinkng about getting a 8 channel dac, and curious about the Flex 8. Iam new to all this and been trying to learn as much as possible. The idea is to end up with FIR crossovers designed mostly in Audiolense. Have your goodselves tried something like these audiolense or accurate softwares, though they might not be always needed I guess.

Good design aesthetic does not preclude high performance always.

Actually, as the number of boundaries increases, the gain also increases proportionally. I will write more details about it probably in my thread.

I use the DSP capability of the Minidsp Flex 8 to the full extent and not only its DAC. The FIR capabilities of the Flex 8 are rather limited since FIR filter capabilities are only available at the inputs and not on the outputs. This makes it limited to only handling room EQ sort of stuff with FIR.
However, in this aspect, the Minidsp flex also can use FIR filters on its output also thereby enabling one to implement FIR filters in crossover. But again, the number of taps is rather limited.

From an absolute performance point of view (in terms of numbers), a DSP solution involving a multichannel DAC like Octo DAC8 pro + a single board computer (eg: raspberry pi)/fanless PC might offer best performance (eg: https://www.audiosciencereview.com/forum/index.php?threads/rpi-camilladsp-tutorial.29656/). This is because it can run full bandwidth FIR filtering on all channels. Earlier I used to run 64000 tap FIR filters on each of the 6 channels of my 3way active system. The Octo DAC 8 pro is one of the best solutions to go with an audiolense/accourate softwares-based set up I think.

The Minidsp models don't even come close in terms of sheer capabilities from that point of view. However, in terms of set-up and user-friendliness, at the moment, the Mindsp is good. I like it.
Other very capable DSP solutions include this: https://danvillesignal.com/dspnexus-dsp-audio-processor
I am not thinking about DeQX because of its cost.

Thanks a ton for sharing. Much appreciated

I spent a few hours only yesterday reading up on Acourate. And to say I was lost, would be an under statement . The Flex8 definitely looks easier to use. And will definitely be an eaiser starting point for me. Thanks again for sharing

Locked into the synergy of an AN chain , upgraded my amp to OTO Phono SE Signature. The EL84 implementation is just magical , in love with these.

Wow for the setup and the song. What song is that? I have left a comment on his youtube post

Edit: Located the song

Very bad audio quality for the song. Whole credit to saregama

I have many songs like this (old records and tapes). But can never discard them as they are songs with kind of poetry, lyrics and musical composition that will never been seen/heard again. Yes, what HMV/Saregama did was criminal.

There should be a campaign to restore these kind of songs in digital format for people who don't own analog formats.

My pet theory is that with AI getting better and better, someone will use AI to take a bad recording, predict the waveforms and apply corrections. I'm sure this will happen some day.

Result would not be nice i suppose. There are lots of modern songs on YouTube sung by AI Kishore kumar, Mohd rafi, Lata. And audiophiles despise even tone equalizers, they would never accept AI recreated songs.

Ugh. I have heard some of those horrible songs. I used to think they have been sung by someone else.

Just getting into this rabbithole.

My first true Audiophile Stereo Speaker setup.

Upgraded from a SMSL amp to a robust Marantz.

What a difference
