My Assessment of Churapa's DDC and Irs Files.

Note this review is done as I am listening to music with the profiles.

Tested with Audio Technica ATH-ANC33is,DCT Player,ExtremeBeats 4.1,Viper4android FX and XHIFI.

Oxycontin(Just the DDC/irs combo with everything else off):

With just the DDC I hear a nice chesty bass response with an otherwise balanced sound. The vocals sound clear with an average soundstage one would expect from earphones. The irs is also balanced sounding. Together it is balanced with a strong bass response but very loud.

Oxycontin(DDC with all of DCT Player's presets):

Oxy with the Dynamic preset adds a slightly choppy bass rumble on some bass heavy tracks. Despite that it provides a clearer sound and a wider soundstage. With the Bright preset it provides more treble centric sound. With the Warm preset the choppy bass rumble is more present since the warm preset is bass-treble based with a slight mid boost. Lastly with the DCT only preset Oxy's sound is smoothed out with a more balanced sound.

Oxycontin(with DCT and XHIFI):

With just my preferred XHIFI setting( lo contour at 30) Oxy sounds very neutral and slightly underwhelming. With both my XHIFI setting and the DCT only preset (my preferred preset) it is much more lively albeit still neutral sounding. The piano and drums in Case's song "Happily Ever After" shines with this combo in fact most of my vocal heavy tracks sound amazing.

Oxycontin( everything on and with its companion irs file):

Once I lowered the output gain I got to fully hear the audio. With my profile the Oxy combo is extremely clear with a nice bass response. Everything is on point with the main issue is that it is too loud even when I have the volume at 50% which is mainly due to the irs file.

Morphine(DDC Only,Irs only and together with everything else off):

The DDC by itself sounds no different than Oxy. The irs file has a narrower soundstage than Oxy and sounds less loud. Together it is basically a bass heavy combo. The mids aren't good for songs with wide array of sounds nor is it good for minimalist tracks and the vocal driven songs(Nothing Compares 2 U by Sinead O'Connor for example).

Morphine( with preferred DCT preset):

DCT only preset makes the Morphine combo sound clearer and wider. The mids aren't any better.

Morphine( same as above but with XHIFI on):

With the addition of XHIFI the mids sound much better for the vocals.

Morphine(with everything on):

With everything on I get a much richer sound. Despite this the treble is at its limits with slight hissing sound.

Perocet(DDC and irs only):

The DDC has a more clearer sound compared to the others. The irs is the same as the DDC. Combined it is a dynamic sounding combo with a wide soundstage,clear and detailed vocals and a strong bass response.

Perocet(combined with preferred DCT preset):

With DCT only preset provides a even clearer sound where every sound can be heard. With a clearer sound also comes a better sounding bass.

Perocet(same as above with XHIFI on):

XHIFI further improves the clarity. Everything else sounds the same as with just the DCT preset.

Perocet(everything on):

This is slightly less balanced than Oxy. Unfortunately with its irs file the vocals sound hollow with my setup. With just the DDC and the rest of my setup the vocals are more forward sounding making the overall sound balanced.

Final Verdict:

DDC/Irs combo:

Oxycontin takes this one as it sounds the great with just these two files. Morphine is great if you LOVE bass but is good enough for other genres. Perocet as a combo doesn't do it for me as the irs let's the DDC down with its hollow vocals.

With DCT presets:

Oxy takes this one again barely as it sounds great with 2 out of 4 presets. Morphine only the DCT only preset sound great with it. Perocet while 2 Of 4 sounded great with it the DCT only setting sounded better with Oxy.

With XHIFI added:

Perocet wins this one barely. All three sound great with DCT Only and XHIFI, Perocet sounded close to my preferred sound signature.

With My Overall Setup activated:

This is where it gets tricky. Morphine only sounds good together but it is a bass heavy combo and not all my songs sound good with it. Oxycontin DDC sounds great but the audio is a little low while the irs has a slightly distorted bass rumble and together its too loud but it eliminates the distorted bass rumble and has a slight vocal echo on some songs. Perocet sounds best with just the DDC as the irs adds the hollow sounding vocals. In the end I went with a Perocet/Pure Balance+-Crystal Clear combo which is damn amazing.
