need a version like 2.4.3 have great energy for rock! resolution less than new version. but drums feels more correct. great drum sound. energy, power, vibration all very good.

EDIT:
after listening to rock with 2.4.3, 2.6x feels boring. 2.4.3 actually has very very good soundstage. the music is even better. makes
think we need to go back to 2.4.3 as template.

2.40.1 is also my good old friend. just vibration not enough. density/airy/sweet/natural. very good for vocal. soundstage sounds better than i remember. think it is improving with OS tuning.

2.4x is king of energy

2.6x feels too tidy in soundstage. 2.4x more organic.

v2.4.3 seems i builded with x86 base (not x64 base), lost source code, in my case v2.4.3 320 also good. first lekt version made for 32bit environment, soundstage good. after i changed to 64bit i always have issues with soundstage. maybe will back to 32bit.
tried many things charateristics of 64bit, but not benefit for sound. high technologue as AVX, SSE or many optimization in compiler setting also haven't benefit. windows audio likes simple model, simple code (but correct and effective). used multi thread/process/class/function..., but not better, even more intense, false smooth/vibration (=noise). i think in 64bits environment Intel makes many simulator, not all things doing by 64 bits once (doing by 32bit or 16bit or 8bit/byte multiple times). large integer as size_t, UINT64,... declared as unsigned long long, seems not true 64it, CPU doesn't understand 64bit.
only base integer as unsigned char, BYTE,... give benefit, fast speed. for example, people says unsigned int is most popular and most speedly for calculation, but i think not that, use only 8bit (byte/char) if i can. processor doing only by 8bit once.

v2.40.1 code very interesting, i prefer its code, only used calculation by 8bit, even not arithmetic, only logical and shift left/right. people have discussion about memcpy function, what is best? try read about it, JC. i have some interesting methods, but need transfer to assemble code for maximum performance.

should try logical and shift again!
think 2.40.1 very stable. soundstage automatically improves with correct tweaks. sound good on both headphone and speakers.

2.40.1 very stable in high jitter OS. for example, i have torrenting, streaming, mysql, browsing, many things running in realtime. 2.40.1 only losses resolution. air kept, emotion kept, soundstage width/height ok.
2.40.1 produces good music in tough conditions.

most unstable software player is XA for high jitter OS. only smooth/airy sound kept. texture, soundstage, emotion, tune etc, everything disappears in high jitter OS!

think XA uses threads (not sure. XS definitely uses intel C++ threads).
threads vs shift.
unstable vs stable.

2.4.3 has interesting method. because 320 no sound for me. 352 also no. i need to use 512.

try 2.68 with "Run this program in compatibility mode for: Windows 7".
intense SQ gone for me.

maybe the intense is caused by win8?!

(also just tried XA in win7 compatibility mode, 3D effects is fixed for me. XP mode actually sounds most raw.)

i cannot select XP mode for lekt player? can you make it happen.

XP mode makes correct sound for XA lol. win8 mode always something wrong. relearning the sound

i think XP mode disable all memory protections like DEP, SHOP, ALSR, all heap and stack security. remember in the old days XP had no security

uploaded:
LektShell.exe v1.16
lekt.exe1644 v1.16 1024

v1.16 1024 use new method read from file and write to buffer while playing. sound seems good, better than other prevous v2.xx. this version use 2 processes: shell+core, like as control program and main program, user call LektShell.exe to run player. think next lekt versions will use this model, sound better but a bit more complex setup, make playlist1.bat file like as:

@echo off
Title LEKT MUSIC PLAYER - Playing... track1.wav
lektshell.exe --file "D:\music\track1.wav"
Title LEKT MUSIC PLAYER - Playing... track2.wav
lektshell.exe --file "D:\music\track2.wav"

although player running with 2 processes but not 100% independing in one computer, shell console window still need keep most simple graphic interface, better with nothing on it.
user can use next_track.bat file with content:

@echo off
taskkill /fi "PID gt 0" /IM lekt.exe /F >nul
taskkill /fi "PID gt 0" /IM lektshell.exe /F >nul

(notice: the first need shutdown lekt.exe)
to play next track in playlist (or stop player in case with single track playlist).

JC, i think now must be do more complex, working with source wav file very bad for sound. need isolate its manipulation in shell process. ah, i like simple one small/mini file lekt.exe but now you will test v1.16, 2-file model really better or not. try it!

nice new model.
1.16 not better. intense. width/height normal.
keep going!
