Swapped in Buf634 with the 220 ohm resistors attached for the high bandwidth mode. Different level of amp now. Complements the Muses01 opamp, which has the Wima cap mod. It's a tight fit, with the buffers touching the case. It's a good thing, as the buffers get quiet warm and heatsinks onto the chassis.

Interesting! Can you describe what you're hearing different now?

It has the character of the Cayin c5.

What kind of resistors did you use and between what pin numbers did you solder them?

The resistor is a 220 ohm value(Vishay Dale). The resistor is connected between pin 1(BW) and pin 4(V-), as can been seen in the pic.

finally my original muses01 and 02 is here.....gonna give it a try later..





initial pairing for original muses01...best pair with buf 634..i try to pair it with LME49600 but find it a bit muddy...

Muses01 + BUF634 give better clarity...ample sound stage too...and quite on a warm side.

more to come..

Please can you pass the original Muses 02 Purchase Link?

as per your request..has been trying very hard to do the macro shot you may click on each picture to have a closer view..

left is the taobao muses02 (fake) and right is the akizuden muses02 (authentic)





left is ori..right is fake..you will notice the top edge of the opamp for ori is more rounded just like what @nasudaijin has described previously..



left is fake....right is ori..again..look at the edge..top edge..


hope this help....damn..now feel like making a report to taobao on this seller selling fake muses ...but they can always deny and say this is the batch issue~..sigh..

Is this original or false?

99% of all the JRC MUSES on Taobao, Aliexpress or eBay are going to be fake, so don't bother. They are one of the most counterfeited opamp in China.

Morning,
So can I solder a 220ohm resistor to the side of a 8 pin dip buf634 between pins 1 and 4 and put them in a e12 Diy directly with no adapter, not enough room on my TO-220 buf634's to solder the resistor

Thanks, perfect!!!! How do you like the 634's with the 01, I have ha-5003 with a 02 and have wanted to try your combo for some time

I personally like stacked 634's in high bandwidth mode. But it doesn't fit into the diy. With muses it sounds very analog. To my ears with stacked buffers, the sound comes close to the RSA intruder. But I lost most of my audio parts in the massive houston flood, so I can't help you with a direct comparison at this time.
