I have had the 105 for a few weeks now, and I have noticed that it sounds a bit mellow, compared to my own player, and that of a friend. The top end seems to lack a bit of sparkle. The rest is fine, with excellent bass and drive, but that softness in the top end is bothering me a bit. Any thought on what might be causing it, and how to fix it?

And Ric, what do you mean precisely by 'removing the toslink connector', and in what way does it improve things?

1. Output sound-coupling capacitors
2. Cheap multi-litz power cable

There is not only about the coupling caps... In the lack of sparkle on highs is involved too the oscillator for DAC (54Mhz), instead for 100Mhz. On channels outputs are used ferrite bead in the signal path, which is not to be there... There are too caps to GND... There is the power system which is not as high quality as it should for that "sparkle". Of course there are also the coupling caps which introduce an unnecessary ESI in the signal path and many other things...
Even though, my overall opinion is that 105 it sounds better as it is than 95 (as it was out of the box)...

Are they using the LM4562 directly after the ES9018 DAC? If so, swap it out for something like LM6172 which is much less prone to overload from RF.

I'm using a good quality power cable (either Russ Andrews or Chord), but the sound is actually the same with a basic kettle lead. Or are your referring to power cable inside the Oppo?

I do like it actually, but with a slightly crisper top end it would be perfect.

I'd like to replace the output caps, but I am not able to find any film cap that would fit.
Does anyone have a suggestion?

the power cable has to be solid core copper, silver plated, double run for each the phase and the neutral for what you are trying to achieve. this is the simplest, least obtrusive mod - no modifications required. for the ultimate speed and resolution you could try pure silver ribbons. avoid anything and everything multi-litz.

the player mods will void the warranty. the sound coupling caps could be soldered back if you want to use warranty for any repairs. you could probably get away with it.

if you don't care about the warranty... work on lowering the noise around the PCB's first; once you achieved very detailed, clinical, fast and reviling sound -> proceed with parts replacement like IC's, caps, resistors, clock oscillators...

... and do not be fooled, air sculptures so freely shown in this thread and claimed to be producing quantum leap will in fact not produce any objective improvement - they will merely change the sound of the player.

youve already voided the warranty and insurance for your house in most cases if youve used a solid core power cable apart from in-wall

The "air sculptures" are not recommended solutions for everybody (only for they who can and know what to do). It were meant here first as informations for those who may eventual be interested in another (unconventional) ways to do things...

How do you know about that "fact" witch will not produce improvements, when you are for sure unknown with that fact, or never experienced such?
But at least, everybody is aloud to have his own fantasies about everything... No problem.

Else is to be appreciated your "in fact" experience with power cables, which can solve the high frequencies issues of an DAC system processed sound...

I`m afraid that hoses insurances and warranties in conjunction with electrical domestic installation, it belong another forum, than this one...
This Forum is about DIY Audio, not DIY Housing...
Thanks for your interest to read this thread, and for your qualified (out of topic) contribution...
