Are these the HA-5002 that everyone is raving about here?

Yes.

I received and installed my HA9P500s yesterday and I'm impressed at first listen. To my ears they are a subtle, but noticeable improvement over the LME49600 while overall maintaining a similar presentation. Compared to the LME, the HA500 is a little more spacious sounding and with really nice channel separation and detail.

 

I also tried LME49990 as the op amp (with both buffers above), but settled back to OPA1611 with HA500 as my preferred combo.

You should do it.

I've spent some more time with the E12DIY today and a few different combos of op amps and buffers, but I keep coming back to the OPA1611 + LME49600 combo. I tried the HA9P500 (HA-500) today with the OPA1611 and with the LME49990, but nothing has quite the space and definition that the 1611/49600 combo provides. I actually preferred the X5's HP out to the HA-500/OPA1611 combo. Not sure if I'm missing something, but short of going for the MUSES which I haven't yet, I can't seem to find anything which improves on the provided options.

 

It's probably worth noting that I have tried these combos only with UM Miracles so there may be certain synergies at play which could completely change impressions with other ear / headphones.

Maybe, but I'm interested to hear from others as to how / why they find the HA500 better

post #1225 of 1772

First post ever. I am currently using AD8620+LME49600 and it sounds pretty good, Close to my DAC. I want to know if MUSES and HA9P500 are really that great of a leap. If both are used, will it be a huge leap?

Just want to point out that it is HA-5002, by Intersil, not HA-500. The SOIC part number is HA9P5002, come as either 5Z or 9Z version. 9Z has a more extended temperature range but the performance should be the same as the 5Z.

Can anyone tell me what direction the HA5002 would be installed on the Brown Dog in relation to this picture? I understand it would be on the under side but what direction. Thanks

Do you mean the orientation on how the SOIC is soldered to the adapter, or how the adapter is plugged into the socket on E12DIY?

 

If it is the first, the adapter has marked dot (on teh SOIC soldering area) to tell you where the 1st pin should be.

 

If it is the 2nd, you can see the square marking on the adapter, tell you where the 1st pin (of the adapter) is. As you can see, the 1st pin is pointing inward into the case (which is opposite to the direction of opamp socket).

Thanks again ClieOS, So what your saying is ...

 

LEAD Technologies Inc. V1.01

(A) would tell me the location of pin 1 as from top view. (B) is pin 1 and the white dot (C) on the brown dog indicates 1?

Sorry - that's my error which has continued through my posts and others'

Correct. There is a a small indented dot on the top of the SOIC chip which should be aligned in the same direction as the dot on the adapter (as you have circled). The indent can be hard to see without a good light source. When installing the adapters into the E12DIY, there is a white square around one of the pins (see back left corners of adapters in the picture a few posts up) which should be at the end with the groove in the socket.
