A New Hybrid from Indeed Hi-Fi Labs: does this look fun? - Page 17

post #241 of 355
I just changed them because I had the caps on hand and I'm a fiend.

However, the power filter cap I really want to change as having a 25V rated cap in a 24.3V situation is very bad practice.

I think the power filter cap is the one that deserves the most attention, The Bravo has a 6800uf cap whereas the indeed sports a modest 2200uf. For those of you with 300-600Ohm cans, i can see the bass bottoming out when the little amp is turned up. I only have 50Ohm cans, are so easy to drive that the 2200uf cap isnt a problem...

I don't notice any bass bottoming out with my HD580s, but will certainly be replacing the cap anyway and I'm sure it can benefit from something a tad larger.

The whole point of swapping the signal caps for better ones is so you can more accurately hear the tube and hear the differences between tubes. It's not a substitute for using a tube you like. It's an attempt to lessen the contribution of the other components to the overall sound signature of the tube. I expect (but since I haven't gotten around to it yet, I really don't know) that by replacing the caps with better audio quality ones, good sounding tubes will sound better, and bad sounding tubes will still sound bad. Maybe, maybe not. Maybe all will sound better. I've got to finish up some other projects first, but I'm going to give it a try. And then do some tube rolling... (again)

cmon headfiers..lets mod our indeed and get the best result

because i fell in love with this beautiful amp and prefer to mod this amp to the highest performance rather than buying new amp with ugly looks..

anybody knows how to anticipate the mid? because i think the mid is a little bit recessed..
post #247 of 355
the mids sound fine to me....in fact with my HD580s the sound is very neutral

How many hours do you have on the new caps, gurusan? Is there any perceptible difference, yet?
post #249 of 355
I finally got around to swapping the output caps. I had some 470uf Muse KZ's that fit. All I can say is I'm glad I did. Only have a few hours listening with the original tube in but I can tell a difference. The lower end seems tighter and a general impression of better separation of instruments, vocals etc. Not an earth shaking difference but perceptible. The mids sound fine to me also. I wish I had a stock one to go back to and do an extended comparison but seems to me it's worth the couple of dollars. Gonna listen some more with the stock tube and then switch to an Edicron 6922 gold pin that sounded good before the cap swap. One thing, I had to get my soldering iron hot (680F) to get a good flow soldering the new caps in. I don't know what ounce copper the board has but it soldered like it was 2oz.

KZ are not bipolar, why not just go with the Nichicon ES, they're made for this application and don't cost too much.

Thanks,

Regarding the issue with gain being too high for some headphones, would a device like this help? Does anyone have experience with this device?

Thanks.

im confused with all the capacitance and voltage specs. should i go with higher capacitance and higher voltage caps?

A few hours, the bass seems to have improved quite a bit.

However I only had around 1 hour on the amp prior to changing the caps so obviously my testing methodology is not that great I'm just glad I have some better components in there.

Just got my Mullard ECC88 and the amp sounds really incredible now. Not sure how but the imaging seems to have improved :/ Perhaps just better separation of highs and lows but I use my headphones for gaming as well and I've noticed the difference.
