post #1216 of 1468

Several seconds as in less than one 1/2 sec fast over 3 min? The clip/fuze makes a 440 tone 441.08. Do the math.  This is just silly.

 

I haven't checked for myself but professionals say that pitch sensitivity begins at 5-6 cents of pitch change. The clip represents about 4. That's an absolute but when everything moves together the issue is even less noticeable. The clips speed bug is non starter and Rockbox cures it for those anal enough to concern themselves with it. There's a difference between reality and Internet 'nollege'wink_face.gif

 

Does anyone else find it interesting that someone who claims sonics sameness due to hardware is pointing at sonics issues due to FW?

 I've always wondered why folks willing to put up with a bit more physical and file size weren't looking at things like the Zoom H2n. The original H2 was around for years, could drive about anything and sounded great.

It was only on one song that I could verify that with so its not like its a huge issue. Not all players are perfect. And at its price point its a non-issue.

If you read my most recent post, I said "firmware and software should ideally have very limited impact, unless it's aiming to enhance the sound"

 

Defective firmware will only lessen the sound quality, is this not clear enough?

Double check. If you read that entire thread, it goes on to show that my info was 100% accurate.

Under the scheme opa2604 need a minimum of 5V.
90% of the inverter needs to be changed to tps60403 or max870 in recent shipments.

ATTENTION all do at your own risk!



Let's start:

Chief Inventor at number 1, from him all the trouble, as I understand it. But I would advise to change and the second!

I would advise everyone to make the switch as in the photo, it will help you immediately turn off the power

and do not give a full break down the player, if you do everything quickly!


1) First, unsolder the battery.

2) unsolder each Inverter.

3) Solder the new, as shown in the photo and

That should do it!

I wish you all successful adaptations!

so anyone with bad sounding t51 tried this? what's the outcome?

I'm gonna try the mod in a month as soon as the invertors are gonna arrive from ebay. But the'll also be repalced stock crappy Opa2604 to LM6172 , so, I am not  confident which mod shall bring the better results... Anyway, after the mod is done, I'm gonna post my impressions, was it worth the effort or was it not.

Which inverter you bought on Ebay? 

Recommend LDO Regulators (5v) to replace.

SnobMod is the AMP section "spaghetti"mod, the hardest and trickiest mod out there, I think I'll try to find a skilled engineer to do it for me in the later future. The mod I was going do perform was much more simple, just the unsoldering of three chips and replacing those with better one... Almost plug&play operation. SnobMod needs tricky measurements and very precise soldering, not an easy task for an average audiophille.

Replacement with lm is just line out mod, replacement tda with ad8397 is headphones mod (by Storb - he has died in this year)... Im use amb mini3 with line out, its like Storbmod wink.gif Its great with tf10 & ue 700 because ad8497 little dark.
