Good question. There has been some confusion on the DAC chips due to a typo or error somewhere in the data stream. Here is the AKM DAC part for each of the new products. Spark DAC 1pc 2ch AK4493EQ Running single Ended Gold X DAC 1pc 2ch AK4493EQ Running Balanced Platinum DAC 1pc 4ch AK4499EQ...

Thanks. I will contact them.

Yes, I can help with that. PM me. First time I've heard about one squealing. The manuf may ask for it back, if you are willing, to check it out.

Yes.

Since both devices are floating and not connected to any external ground such as the AC ground, I would expect no issues with headphones. You shouldn't have any ground hum though even at 2 on the dial. Cable perhaps?? Or something coming from the source? OTOH, if you're good the way it is no...

Whether normal or not depends partly on the rest of the system. Does it hum during normal operation playing music?? Does it hum when the amp is on and you plug in the headphones?? If it only hums when plugging in the headphones when the amp is off then it's probably a grounding issues that is...

Answers to Rattle and Zachik. The LP DAC uses an AK4499 4ch Chip. It will, obviously, be balanced with the expected complement of ins and outs. It will also, obviously, be in the same type enclosure for stacking. :) As for LAuX and DAC output, I think this is a real estate issue. The rear...

I think I can. Give me a day or so....

The answer is both simple and hard. Sahmen's answer above captures most of it, so I'll mostly repeat. The Crimson was single ended output, but since it had much higher rails could do 4-5W at 50R. The LAu, being balanced, could do about 9W into 50R. The LP, as you all know, is a balanced version...

Gents, I made this informational post elsewhere, but now that we a thread here..... This may answer questions that have been asked or may be asked. 1. The LAuX is exactly the original LAu, but obviously reduced to SMD sized components and lower power. 2. The power output is identical to the...

Sorry about any confusion. This just seemed like a good place to put the info. There is, indeed, a Platinum DAC coming. Gain is 2X/6X. No remote. AND, not trying to get anyone to jump from their LP to LAuX. :) It's simply that when a new amp like this comes out there are questions and I...

This is a real PITA, I know. I am surprised though bc I know how these things are tested. A dead brick should never get through the process. It's just too difficult. Hmmmmmm

It is ok to go the other direction, SE to Bal so long as it's wired right. :smile_phones:

Hello folks. I'd like to address the possibility that some owners are thinking of using the 4 pin XLR output as a 3 pin TRS by tying two of the pins together as a common ground. If you are thinking about doing this DO NOT DO IT. EVER. The balanced outputs are two floating outputs with pos and...
