all mentioned ARE buffers; buffers are there for a few of reasons,

1. to increase current (not voltage)
2. to take an impedance that is higher than we would like and output with a very low impedance, this gives a wider range of headphones that can be used effectively. the ideal buffer has infinite input impedance and infinite output impedance
3. this way the buffers are taking the 'weight' so to speak, leaving the opamp unaffected by the load (your headphones)

as far as texts, sorry I dont know anything off the top of my head, but google is your friend. they can be bought online at places like mouser and digikey safely and cheaply. but not on adapters. some will be available in a DIP8 package that does not need an adapter. you can try browndog.com, but they are a bit pricey.

The Silmic2 that I used are 6.3V 220uF

Actually I was thinking of building a rig with a 2.5V DC and some signal generator to generate pink noise to burn in. That is the exact condition.
Using the output of the hifi the DC offset is not there and it would not be suitable for non polar capacitors which is being used in the D10.

Will start burning in BLACK GATES tonight. Cannot wait till 100 hours is up for each capacitors.

There are only a very small handful of places you could buy Black gates, I could still pick and choose today, But looking at the stock level better buy fast.

Initial impression of fresh Black Gates,

Sound is whole meaning sound stage is small, Vocal is full body slightly warm. Instrument is distinct but not as hair raising as Silmic or the KZ. Vocal not as smooth as the Toshin.
Lots of sibilance. Bass does not goes to the very low end, but when it hit it is hard and solid.

But is is one very musical capacitor. Overall the presentation of the music is balance and very enjoyable.

Now the long wait for burning in. Some catching up to do so that all my capacitors can tested at the same burn in age.

Hey Madwolf, would you say that the stock caps are worse than all the ones you rolled in?

Not that any of us need another Amp, but iBasso said they're gonna start development of a new Dseries amp after Chinese New Year's.

I've had my d10 for a little over a month now, I'm truly liking the versatility! Sound is pumping to Sony cd-3000's from an imod4g. The dac I use as a secondary source on occasion.

My opamp setup is completely stock; I'm under the impression it's probably best to keep it like this lol, BG mod is interesting ~ where would we get these?

BG's are getting harder and harder to get. The opamp upgrade is a worthwhile and not too expensive path.

I just opened mine up to swap opamps and saw that it came with a BG cap, stock.

Agreed. And it's also so simple that even I can do it.

Hows D4 with best opamps compared to D10 with best opamps ?
Thanks

Both get closer in sound to the RSA P-51 which is my favorite, but the D10 never quite reaches the treble perfection and space/ambience of the P-51 while the D4 does.

Can D4/D10 drive DT 880/990 Premium 600Ohm ?
Thanks

^^ NO, not IMO anyway. it will make some noise, but not the best kind
