I am by no means an audio gear expert, but I have the O2 amp and HD 6XX (the combination you mentioned). O2 has a headphone jack (to plug in your headphones), a port (for power), and RCA cable inputs. So, the only possible inputs to the amp are RCA audio cables (For Left and Right channels, in white and red). So, how do we connect the music source to the amplifier? One possible way is, use a 3.5mm to 2-Male RCA Adapter cable. But I am not sure if the audio quality will be clear, since music will be amplified but the clarity will be as good (or bad) as the in-built DAC in your laptop/desktop or phone. It makes sense to buy a DAC, from all the sources I have read. You can buy the 3.5 mm to RCA cable for 9$, and check the audio quality (Frankly, I have not checked it too, though I assume it should work). I am using 2 devices as DAC. End-to-end connections: (1) Laptop (source) -- > Centrance DACport HD (DAC) --> Objective 2 (Amp)--> Headphones (Senn HD 6xx) Apple Mac --> Centrance's USB 'slot' =Centrance= Headphones 'slot' ---> 3.5mm 2-Male RCA Adapter cable to the Objective 2 amplifier --> Headphones. (1) DAP (source and DAC) --> Objective 2 (Amp)--> Headphones (Senn HD 6xx) Shanling M0 (Headphones slot) ---> 3.5mm to 2-Male RCA Adapter cable --- > Objective 2 amplifier --> Headphones. The DAP acts as a DAC since it has a very good DAC chip. I connect HD 6xx directly to it too. It works great (as loud as I can handle, and very clear). I almost don't need an amp.

Does Objective 2 with Dacport HD sound any better, than Dacport by itself?

Not a huge difference, but it is definitely perceptible. 'Better' is subjective, so I will say this - The clarity is as per the source and DAC, so with the amp (Objective 2), I have room for some more volume. Dacport HD on its own is clean and loud, but I have it at max volume at high gain when using the Senn HD 6xx. Adding O2 to the mix, I still go to high gain, but I stop short of the max volume (say 75 to 80%). This is pretty loud for me, and I listen for shorter periods. Note - I am 43 yrs old. If you are a decade (or more) younger, you might need lesser volume than me, with any setup (to hear the equivalent loudness). In hindsight, these buys were learning/experimental decisions (I cant return since I am from India, far from USA). Would I buy this combination today? Not at all. I might buy a good sub 90$ DAC (Topping D10, SMSL 10th MKii) and a powerful sub 100$ amp (Magni Heresy or JDS Labs Atom - 99$). And retain the Dacport HD - that's a keeper (for 100 ohm to 300 ohm phones + portability).

Drop + THX Panda -- Bluetooth Audio Clipping Whenever Resumed from a Pause of More than 2 Seconds
I don't have much experience with Bluetooth headphones and figured I'd ask here to help set my expectations a bit. I just bought some Drop + THX Panda headphones. They're well reviewed for sound quality and supporting higher-end audio codecs, some of which Macs support (eg: aptX) and some of which they don't (eg: LDAC). Anywho, upon unboxing them and pairing them to my 2020 iMac running Big Sur, I noticed that audio over bluetooth sounds totally fine until it's been paused for more than 2 seconds. When I unpause, it almost feels as if maybe the headphones are coming out of some standby or low-power mode and are rushing to start a new bit stream. The sound is clipped / distorted for a second or two until it "catches up". This is particularly annoying for things like notifications and other sound effects which, by nature, are essentially really short audio clips. I can't find anything online explaining if this is normal behavior or just a shortcoming of bluetooth or these specific...

DAC/Amp Combo for MASSDROP X SENNHEISER HD 6XX HEADPHONES
Hi! I am seriously considering buying the HD 6xx's, and I'm very new to advanced audio. I was wondering what is the best DAC/Amp combo for these headphones around $100. Thanks in advance!
