Sounds like you have an issue with gain and not power, so I don't think a balanced cable for your HD 6XX is the answer. Is the volume on your computer maxed out?

Thanks for responding. Yes it is. At the very least I leave it the same when I plug my headphones into the 789 directly and then swap into the BTR5 directly.

Okay. What gain setting do you have the THX amp on? I looked it up; you should have three gain settings (low, mid, high).

When I plug the BTR5 into the 789, and my headphones into the 789 (SE) I start with it on gain setting 1 out of three. To get it to the same “loudness” as I’d just experienced on the direct connection to the BTR5, I have to both increase the volume on the BTR5 up to its max and switch the 789 to gain 2 out of three, and turn the volume knob on the 789 to about 3 o’clock. Is this normal? I guess I was expecting that the volume on the BTR5 would be lower...

This is normal. I wouldn't sweat it at all. I'd actually use gain 3 and turn the pot down accordingly almost regardless of source (unless I was getting channel imbalance with sensitive stuff). Less feedback used = better sound.

Gain one on the 789 is actually a negative gain (reduction) so it absolutely makes sense that gain 1 is lower than the BTR alone, it's designed that way for easy to drive headphones/IEMS. If you have gain 2 engaged on the SE input that is 0db, aka no pre-amp gain is applied to the input voltage. If the BTR5 doesn't output more than 2 or so volts the 789 can be ran on high-gain (gain 3) with no concerns.

Distortion with playing music from iTunes on my Mac with my HD6XX headphone!?
Here's my setup - Cambridge Audio DacMagic, Monolith THX 887 Amp. When listening to lossless music from Apple Music from my iPhone, it works fine. But somehow switching it over to connect to my MacBook Pro, the sound is greatly distorted!? The odd thing is with this setup, playing a Music Video from iTunes or youtube, it sounds fine. The terrible distortion happens only when I play any songs from Apple Music. What could be the reason?! My MacBook Pro is running Mac OS Big Sur which supports Apple lossless. Anyone having similar problem?!

What to do with one side dead (Focal Elex)?
I have a pair of focal elex headphones. By far one of the best I've had but one side went dead yesterday. Not the cable issue and read that it is common with them. Could you advise what to do? Can it be fixed locally? Given it right be the driver or copper cable inside?

Clamping forces of Drop-collaborated headphones
I have a fat wide head and am sensitive to the clamping force of headphones. My question is, why are the clamping forces of Drop headphones reportedly higher than the ones from the original manufacturer? For example, according to measured tests on rtings.com, both the Sennheiser HD5xx, HD58x, and HD6xx have much higher clamping force than their respective Sennheiser original models. This also seems to ring true with the Drop x Meze 99 headphones, where Meze 99 forums are saying there's almost no clamping force but the some on the Drop forum are saying the collab version's clamping force were "quite high." Is Drop requesting that headbands be tighter on the collab versions? What's going on? Also, can anyone suggest me a comfortably wide/large headphones? I'm currently using AKG 7xx and they're super comfortable.

THX AAA 789 Amazing sound
Online reviews spoke highly, but I was suprised by the detail in the sound. I was using a Dac/amp with an msrp of 1400 so I did not expect much. I did notice an immediate clarity improvement. Music, specifically words were no longer blurred.Singers seemed to make more of an effort to enunciate words more. Even using a $100 DAC the sound was top notch. Drop hit a home run with this product.
