Aune T1 USB Tube DAC+ SS Amp Discussion Thread ***See first post for FAQ--Updated on 02/14/15*** - Page 268

post #4006 of 8013

Long-time lurker newly minted contributor here.  I just wanted to take a moment to say a big Thank You to this community for all the valuable, in-depth information shared about this (and other!) amp/DACs.  I feel like I was able to make an informed buying decision of a product that will grow with my interest.  I'm currently enjoying the Aune T1 to drive my spanking new Q701s and my old stand-by HK3390 receiver + Model 6 combo in my office for listening to a wide range of music sourced from my iMac.

Keep searching arcorob! I'm interested in swapping caps too. If I find some time later, I'll see what I can do, but no promises. 

 

And spacequeen, I think you've made a wise investment in the he-400. Enjoy. HF states a burn in period of 150 hours, just for a fyi.:atsmile:

Great thread! I love finding little gems like this.

I don't think the T1 will be able to properly power the he-500, but I don't know for certain.

 

Thanks, I'll probably get the he-400 although in the future we can add in a more powerful amp and just use aune's dac. Here on Amazon UK the he-400's are £370 and the he-500's are £625 if that would help put things into perspective.

 I can also get the hd650 at 200 used but it seems that Orthos are superior?

Thanks...I will. I know I have them because of some leftovers form a recap project and a planned one that did not pan out. I have a box of brand new high grade caps. The thing is, I check Mouser.com, partsexpress..even ebay...Can't find better than 10% , most 20% which on a 50v cap could swing 10v

Capacitor tolerance refers to the capacitance, not voltage.   A 100uF 50V cap is still a 50V cap, at 20% tolerance, it's capacitance could be anywhere from 80uF to 120uF and sill remain in spec.

Yeah, I checked mouser and digikey. I tried just googling a 47uF 50V cap and got mostly 20% tol, though I didn't sift through all the results. I didn't find anything with a better tolerance either. I may try a power electronics engineer I've worked with in the past to see if he has an thoughts.

 

Manishex, while I think you'll love the he-400, planars vs. dynamics, is preferential. I can't say any one is better than the other, because it's really up to your ears. I was considering the Sennheiser hd-600, but decided on the he-400.

 

In the end, the only way for you to truly decide what's best, it to try both. :wink_face:

A higher voltage rated cap can be used in place of the current 50V cap as long as we stay at the same capacitance. Also, they need to physically fit as well.

 

I think we should, if we have knock off caps, replace them with a Nichicon cap with the 10% tolerance (and same ratings) and see what changes/improves. I don't know who makes a 5% aluminum electrolytic cap, so I think we should start with a better known component rather than search for a hard to find cap.

 

It's a safe bet to assume (I know, I know, assuming here) that we may have a 20% tolerance cap in there now so it'll probably be worthwhile, to those who want venture down this path, to just try a better quality cap. Thoughts?

 

Edit- missed a quote.

Done!

Thats good because I may find some 5% caps in here but not sure. And size isn`t important for me since I`m doing wooden case for my Aune T1 anyway ;)

 

Can anyone tell if those are also worth for changing?

Or are Nichicon only way to go?

 

Edit: Thanks Salvatore, will update that post with more information later.

You are right, I said it backwards...DUH...

 

I still like to go with tighter tolerances than 20% though..just hard to find...totally frustrating

post #4020 of 8013
No need for anything tighter than 20%. That is pretty much the standard. I updated my post with links to the caps I used in mine.
