Wima and most film caps tend to sound sharper and more edgier. I am using Silmic II most of the time - as my opamp + buffer choice usually is aiming toward transparency, I think the Silmic II balances it back slightly with its more musical (yet still mostly neutral) and relaxing sound.

 

Many thanks for the detailed presentation. I have ordered many components but nothing received yet. So I tested today to change the stock capacitors but I was really disappointed. The music has lost the room information, it sounds dull. So I soldered both stock capacitors to a bypass configuration. I need to use thin cables to do it. The result is pretty good. Very clear room information and a strang and black bass.

I use it with LME49600 + AD8620.

 

In the next few days I await the delivery of my orders. I ordered the silmic caps, the MUSES01/02, the HA-5002 (named as HA9P5002-5Z) and the brown dog adapters. Most of all will be here very fast but the HA-5002 has 13 weeks delivery time.

I will share my experiences when the first parts are placed in my E12DIY.

 

 

Edit: It sounds very well with the AKG K3003i. And only with the AKGs.
My Audeze LCD-2 sounds not really bad, but it is far from good in this combination. This is not important for me because I want to use the E12DIY only with the AKG headphones.

 

Edit again: I solded it back. Only the Wima capacitors are working. That makes a better room impression. More and better high frequency.

James said over in the X5 thread that the Chinese market prefers a warmer sound. I wonder if the stock replacement caps (Elna Tonerex) were provided for that market?

Look at the below graph, the R1 to R2 is the shoulder. R2 to the slimmer end is the pin that insert into the socket. So regardless of how far you trim the pin, you will never get pass the shoulder as that's what stopping the whole pin from going into the socket. The only way around it is to remove the whole pin together and replace it will a pin that has shorter shoulder. But then you need to order special pins for the job.

As for your second question: It is because on your normal BrownDog single SOID to DIP adapter, they come with pins with short shoulder because they are meant to mount on only one side. If it is a dual SOIC to single DAP, they will have the long shoulder pins as well. The issue is, HA-5002 adapter only comes with dual-to-single version and we have no other choice.

If you order the BrownDog adapters with the standard pins there is no need to trim them as they fit in the E12DIY. At least the ones I got did.

This issue I think refers to the Brown Dog adapters specifically made for the HA-5002 --> BUF634 configuration

I know, here is a photo of the Browndog HA-5002 to BUF634 Adapter (p/n 110101) in my E12DIY.

I'm looking up the Silmic IIs on PartsConnexion as we speak, and they come in 2 voltage ratings: either 50V or 100V. Both caps are of the same size and dimensions for the 2.2uF units.

 

Seems either would work, but is there any bearing on the sound quality?

 

I've read in the past how the higher wattage models of certain tantalum resistors sounded better, but this is a different thing all together. Still, it makes me wonder if there's something about different voltage models that may be audible. Anyone experiment with it yet?

 

How did those Blackgates work out? I recall they didn't quite sound good, but that was a while ago, and it seems those BGs take a lifetime to burn in. I probably have some BGs sitting around in my parts box, but they may take too long to settle.

 

...

 

The minimum voltage to use is 6.3V (which is the lowest rating most caps have). Anything above is fine. Some said higher rating gives stabler performance, though I don't think there is the need to intentionally go for a higher rated voltage as the difference will probably be too small to notice in audio application. Personally I'll go with 10V~25V. You don't have to order Silmic II from PartConnexion as Mouser carries them in bigger variation. 

 

Jamato is a firm believer in the BlackGate, I am not, at least not with the NX Hi-Q I have (which is said to be the best sounding among BG by some). I have a pair of BG that has 500+ hours on them, and don't sound that much different than those that only have 10 hours on them. Maybe they will turn out better sounding in even longer hours, but I have better sounding caps on my hand without the need of burn-in and I'll rather not wait for magic to happen.

Film caps do often carry a lot more micro-detail and has a very clean sound. What they often don't have is texture on the mid to bass region (I guess that's what 'cloud' the sound for you?). Electrolytic tends to fill the room up, where film caps tend to leave the room open, so to speak, A good compromise of both is the AVX OxiCaps actually, which has a sound that is right between them.

Hardly. I haven't really saw many Chinese E12DIY owner change the caps. The few that do are mostly going for Silmic II or something more exotic.

I actually do have the standard pins version of the HA-5002 adapter. Again, it depends on the casing of your particular E12DIY on whether the unmod'ed adapter will fit inside or not, because there is only 1 mm or so room to spare. The reason to suggest for trimming is because I have observed that the actual pin length that inserted into the socket is 1mm or so longer than the socket's depth. So trimming a little bit off not only won't affect the function, it should give you a tighter fit.

 

Basically, if there is room to spare with the unmod'ed adapter, you are on the clear. But if the adapter is getting too close, then trimming a little off will give you the room to install the adapter safely, without risk of short circuit (and insulating tape is a must as well).

My MUSES01/02 are arrived. I tried both and I can't hear a difference. Is there anyone who can?

post #1163 of 1983

So far I can say, the MUSES are not the best for me and my AKG K3003i. Much money for nothing in my ears and eyes.

A lovely improvement is the change from the capacitors to the Silmic II.

 

Now my best configuration is:
LME49600 + AD8620 + Silmic II capacitors (22uF 25V)

 

This sound is really what I like. Great room impression, clear but never rough, strong black bass with a lot of authority. The voices are real credible and applause sounds like applause and not like heavy rain. I hope I could describe what I mean.

 
 
btw.: I got a private message asking where I got my MUSES. It could be a fake.

I want to make it public. I bought my MUSES here.

http://de.mouser.com/

Put MUSES in the searchbox and you will find what I have ordered.

Is there anyone who knows something about that?

Pretty sure I can tell them apart, since they sound very different to me. But you like what you like, and certainly no one can tell you what you should like. However, I do suggest giving them sometime. Force yourself to listen to one combination for a week, then move to the next. See if you still like the original combo as it is. At worst case, you can still sell the MUSES off for a good price in the forum, since you can show people the Mouser receipt for proof of authenticity.

 

Also, if you haven't done so, try different buffer combo as well.

Yes, I'll do so. I'll try the different combos for a week. That may be a good way.
I ordered the HA-5002 buffers and the brwon dog adapters, I believe that could be a good combo to the MUSES. But there is a delivery time of 13 weeks. I have to wait so far.

Cancel the HA-5002 order from Mouser and get it from RS Components instead, readily stock and cheaper price too (they run under alliedelec.com in the US). Element14 (newark.com) and digikey.com also carry stock.

Order canceled and new order placed by DigiKey. Thanx guys!

post #1168 of 1983

I changed the amp now and start hearing one week with this combination:

 

LME49600 + MUSES02 + Silmic II capacitors (22uF 25V)

 

May be the buffers HA-5002 will come next week, than makes comparing the 2 MOUSES more sence.

post #1169 of 1983

what are the chances of receiving fake silmic II caps when i buy them from eBay?

 

and i see different versions of the ha-5002; a dip version called ha3-5002, and a solder on version called ha2-5002, which ones to get, and again, is eBay a safe harbour to get them from?

post #1170 of 1983

I received my LME49990s today and soldered and installed successfully. Early impressions are that they sound a bit thicker and more intimate than OP1611 so not sure they'll stay installed, but for now I'll give them a few commutes to see... (using with stock LME buffer)
