Of course, you can always try. Unfortunately, what you describe can very well be a mechanical issue. That makes it impossible to find replacements parts unless you buy another one and steal the parts from it. Mechanical buttons are the worst, because in most cases they were all custom made...

No chance. I'd pursue damages due to the shipping - either to the seller or the shipping services. If there wasn't any shipping insurance, lesson learned, I guess. Even Sony would just have replaced entire assemblies back in the day, not troubleshoot the insides of a small disc player. If...

Just as a further example, I've sold several products at Beezar Audio that involve conversions between fully-differential and single-ended. The PupDAC uses a TI/Burr-Brown DAC chip that TI/Burr-Brown has manufactured for almost two decades now. The PCM1794 is fully-differential with four...

He answered sufficiently that his post was a rebuttal to Whazzzup's claim that an SE to Balanced adapter didn't exist ... they (plural) most certainly do. Perhaps if he had quoted Whazzup's post along with his, it would've been easier to understand the context. I understand the possible...

Saw this late, but you need to clarify that statement above. What exactly would you consider better and at the price? IMHO, the TREAD hits the sweet-spot between audible power supply noise removal and price. It's true that Jameco offers linear-regulated walwarts that perform at nearly the...

I apologize, but I'm not sure how streaming is going to work outside of the streaming app itself. For that matter, that would include USB Audio Pro. I don't see how you can use that app for a streaming service. Maybe I'm missing something, but if the media player app is looking for all sort...

IMHO, the perfect complement to the HD650 is the HD800.

JMHO, but I prefer Poweramp. It's slightly cheaper, too. Your sub-50 GBP IEMs may benefit from an outstanding equalizer and sound enhancements that are available in Poweramp. I've used it for years and with FLAC files exclusively when I was running. It's tough to get full bandwidth sound...

The Audeze LCD 2 is probably the historic planar game changer and the one you should get, if you are interested in "official" milestone headphones for the last ~20 years. Similarly, the Sennheiser HD800 is that for dynamics, with the Focal Utopia or Focal Clear close seconds, IMHO. Be...

JMHO, but I don't think a switching power supply is the way to go for 200V in a tube amp. Anyway, good luck!

The issue is in combining the outputs of a fully differential amplifier into a combined-ground TRS jack of any size. If the amp is truly fully differential*, you will be shorting the outputs with the common ground in a TRS jack. * There is a big misconception in audio that is unfortunately...

I never had any trouble with noise on IEMs with ECP Audio tube amps. All of the tube amps are transformer-coupled (Torpedo, T2, T3, T4, etc.) and do well with IEMs. I still have a pair of Ety ER4 MicroPros that sound great on my T4. BTW, the power stage is most important in controlling noise...

Want to know what's changed in the world, btw? Check out this thread right here in the Introductions, Help, and Recommendations section: https://www.head-fi.org/threads/best-strains-to-smoke-while-enjoying-music.971907/ I'm not implying the referenced use is new, but a forum post about it and...

The single biggest change is not really in headphones, per se, but in the overwhelming move to digital audio in terms of compressed (mp3) and uncompressed (FLAC) digital audio files. Meaning, a DAC and PC, along with the mobile equivalent smartphone, have become the audio source standard for...

Actually, the term should be Fully Differential, not Balanced. In the pro audio world, a device is fully balanced if balanced connections are available on the inputs and outputs. This can be confusing, even purposefully misleading, where some mfrs try to claim "fully balanced," knowing that...

It's called tonal balance, which is quite different from output balance or channel balance, which is why I curiously clicked on this thread. ;-)

Yes, I think going to balanced cables and balanced drive amplification (fully differential) will be an audible difference with your Senns, all other things being equal. BTW, the grounding superiority is in non-connected cabling from the headphone drivers to an XLR connector (IOW, not using a...

I'm not sure this will end up working like you want. As you noted, you can't pull the phono output out of your receiver without it going through the pre-amp section. If you then connect one of the receiver's line outputs to your headphone amplifier, you're double-amping, with all its...

ANY frequency response quoted without a dB variance is USELESS. You could say 20-20kHz, but the device might be down -80dB at 20Hz. You would never hear it. Any source or amplifier should respond with 20-20kHz with no more than a few tenths of dB variance over that range. When it comes to...

There are two primary features for going balanced, especially with 300 ohm Senns: 1. XLR and balanced connections are superior for grounding. You gain several dB in noise advantage with balanced connections. 2. The voltage gradient is doubled with balanced amplifier drives (also the slew rate)...

With 7TB (I have close to 5TB), the only realistic solution is a NAS (Network Attached Storage). Look up NAS and you'll find many options. They're usually easy enough to connect and setup file sharing. Once you share your music to your home network, every device will be able to see your...

Just an FIY, but you'll enjoy the eventual upgrade to the HD600 and then HD650. There is a decreasing amount of high-midrange distortion as you go up in the headphone model# from 580 to 600 to 650. The big break was between the 580 and the 600, as the first prototype was the 580 Jubilee and...

Unfortunately, Sennheiser made the 580 first, the 600 second, and the 650 last. The 650 is simply more refined, period. You may find people who prefer the 600 because it has a treble spike that may make it sound more detailed*, but put it on very, very good equipment and you will hear the...

Solid first? It happens to me all the time. I always say NO, but it pains me that customers feel compelled to ask. The problem is these governments (not singling out one or the other) have no idea of the effect of those customs charges and VATs. They only think it increases the money going...

I agree that you must be talking about music file resolution, because 384kHz is one of those magic numbers used for resolution limits. However, your question as paraphrased is worth a response - why is it important that an amplifier have a bandwidth greater than 20kHz? It's because the nature...
