Accounting for slight hearing loss


On a whim and with a suspicion, I recently had a hearing test and it showed some loss in left.  Mainly around 3k and then recovers some above that.  I had noticed (after many good tips gathered on Agon) after really paying attention to set up and room, featured vocal/instrument was often right of center, almost never left.  Mind you, i still hear all freq, even quite  high and get great staging but often, its annoyingly with a right bias.  Maybe that's where he's supposed to be!  Thats actually not a trivial point.  Funny thing, I can listen to MD Kind of Blue in mono and I sense no shift. Quite opposite as instruments still have some staging. Go figure.  

Any tips or tweaks to compensate?  Ok, here's where I might be all wet.  Lower resistance to tweeter in left XO (phase issues with right?)  A mod to extend left baffle above the tweeter some?  Simple "Left" on amp works but isnt freq specific.  Im suspicious that using an EQ unit will degrade overall sound although that seems the most obvious.  Do they?  Speakers are Madisound kit Klang+Ton NADA designed with Scanspeak Illuminator drivers.  In Lee Taylor cabinets.  Amp is Rogue Sphinx V2 (A/D). 
Thanks in advance.  Otherwise it's a tad "L" on the amp.

A DSP between my transport and DAC will convert with it’s own DAC, do its eq, then convert back to the undecoded format (ADC). Then my MHDT will see it as before.


Sorry but for this specific case, your example is incorrect. The signal remains in the digital domain and is converted to analog only at the last stage, the DAC.

Transport --> S/PDIF --> Math is applied --> S/PDIF --> DAC

DSP, or Digital Signal Processing, performs math on the digits, so the S/PDIF data stream is practically it’s native language.

An example of what I’m suggesting in this specific case would be this:

https://www.minidsp.com/products/minidsp-in-a-box/nanodigi-2x8-b

It has digital inputs and outputs only and not a single analog part inside. :) In my case though, since all my signals come from Roon and I lack a spinner:

Roon (CPU does the DSP to the digits) --> Wifi --> Streamer --> USB --> DAC

Again, no conversion to analog happens until the last stage, where my Mytek Brooklyn takes the output of the streamer and feeds it to my integrated amp.  Lastly, third option, is to use a miniDSP with built in streaming, AND digital inputs:

So, in the third case, your transport AND your streaming goes through the same device, adding EQ to everything equally. In all three of these cases your existing DAC is the only place where digits are converted to analog signals.



Best,

Doesn't matter what anyone says the dacs in almost every DSP/room/speaker/xover box is usually rubbish compared to your own hiend dac if you have one, and it's sound will never be what it was if it's in there as well.
There's too many processes going on that pollute and sterilize the digital stream, far better off just with the Schiit Loki done in the analog. And retain the sound of your hiend dac the way it was.

Maybe that's why I'm not recommending any such device.

Does the same corruption (sterilization) as what your recommending, even in front of your favorite dac.
