I have a set of 58X Jubilee headphones and a Logitech Z625 speakers.
Would it be right to use the preamp of this amplifier with the Z625?
Since the sub powers the speakers it probably has it's own preamp (I don't know for sure, since I'm new to all this stuff) so I'm left wondering if connecting the preamp of this headphone amplifier to the sub could potentially damage it (or any other part of the Z625) 🤔
Can somebody help me with this?

[DROP + THX AAA ONE LINEAR AMPLIFIER]
What amplification method does this amplifier use?
EX) CLASS A? CLASS AB? CLASS D?

i See.
Thank you for your kind answer.
By the way, I want to get it shipped quickly.
March 2021, it's too late.

I can tell you it won't power passive bookshelf speakers. Not sure if you can find a way to hook up powered monitors, but this is a headphone amp first and foremost, and a darn good one if the 789 is anything to go on.

Does/can this - or many other amps etc - come with a UK plug?
We don't all live in the US or Europe (of which we're no longer a part anyway!).

I really wish this had at least two inputs, that would make it much more useful. I think one input should be able to function as a phono input.

Tubes aren’t necessarily bad, Or the best thing ever, I’m just cautioning that the reality is you have to work for them a bit, which sometimes distracts from sitting down and listening. Some people feel the ritual and effort makes them focus and appreciate the music more, similar to vinyl aficionados. But if tubes achieve anything, it’s that newer doesn’t necessarily mean better, and you don’t necessarily need to wait for the latest upgrade to get an extremely good sound.
The Amperex tubes with the “bugle boy” stamp on them are generally regarded as very good, so I’m not saying you should immediately discount them. It’s just MY sample is super sensitive to bumping the table, and I think there’s actually a low, persistent ringing sound just on the edge of my hearing. Could just be mine, but that’s the risk of trying these eBay deals. Researching tubes and watching eBay for good deals can be a fun treasure hunt, but it does take time and might pull your focus away from just enjoying music. I also have a well-recommended JAN tube that’s good but a bit grainy, a second Amperex that’s clearly a dud, and four Vokshod Soviet tubes from the very early 80’s, and I’ve only tried one because it has no ringing and sounds so good (and also my bias pots seem stuck, but the voltmeter readings are good). My first tube that was supposed to come with my custom made amp actually shattered in shipping – I almost cried, and I had to carefully clean splinters of glass out of the amp and RCA jacks! Lastly, all tubes have a lifespan, and eventually burn out... but it’s not so bad, that Soviet tube I mentioned was running in my only amplifier for two years of use, and I still come back to it sometimes.
Tubes aren’t automatically “better” or “worse,” they’re just different. You’ll see people raving about how the Woo Audio fireflies amp is so pretty (and not bad sounding either), and has made some great sounding tube amps as their flagships, and Sennheiser’s $60k HE-1 Orpheus “system” includes an amp with eight tubes of comparable quality to the best Telefunken tubes. Sennheiser also put the tubes inside of quartz vials to protect them from EMI... it’s actually an electrical hazard to have bare tubes out in the open where you can touch them during operation, not to mention leaving them to be like antennas for the squelches and squeaks of cellphone texts and other wireless signals.
So, I don’t hate tubes, I just think it’s worth understanding what the reality is like. If you do decide on checking out tubes, I do like Woo Audio, Felix Audio, Glenn’s custom tube amps, and I do hope someday to hear a Darkvoice. For beginners, I really like Garage1217, which is a small business in the US that follows a similar design as the Bravo and Indeed amps (and my SET hybrid), except it comes with most of the capacitor and design upgrades you would eventually want from a Bravo. I would also recommend something to act as a Faraday cage or an EMI Shield to go over the tube.

I would love if this unit had multiple Inputs. It would be great to be able to plug at least two or three sources into it since it can be used as a preamplifier.

Single ended can be built just as powerful and clean as balanced. Balanced with todays tech is just a money making scam.

like The guy who posted this message to which you also had replied, I too mean “today’s tech”. But the 299 for the thd amp is a midrange price imo. It’s single ended and it has better numbers than many older balanced amps. So imo, it’s a waste of money if you buy a balanced amp spending more than 300 thinking it would be better than the single ended.

But the balanced out on the 789 is better, assuming that's what you're talking about and not the One.
https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-massdrop-thx-aaa-789-amp.5001/ The balanced output allows for a much higher power output with slightly less distortion, making the balanced output cleaner at the same relative volume as the single ended. Of course, the difference isn't audible at these levels. The 789 is already a great example of how a balanced connection can give you better performance. And it should be noted "fully" or "true" balanced is not what we're talking about here in regards to the 789 (the engineer mentioned it didn't need to be because there would be no benefit), it's all about the connector. OP is correct in that single-ended output can be engineered to be just as powerful and clean as a fully balanced setup as far as our ears can tell, but that doesn't mean it's always "just a money making scam." For example, check out the Topping A90, which is even better than the 789 for a similar price (pre Drop price reduction) and better balanced output performance. https://www.audiosciencereview.com/forum/index.php?threads/topping-a90-headphone-amplifier-review.13592/

yes, Ihve seen a steady drop of its price most probably because having such a slanting chassis wont sell as much as expected.

Top 6 Best Headphone Stands in 2020
Whether you have a desktop computer, laptop, or simply a smartphone, we all have a branded headphone to enjoy music in the best possible way. However, keeping the headphone organized with its wire and cable is a tough challenge.
In my opinion, when it comes to headphone stands, I feel that a lot of people do not really pay the attention that they require, in the first place. I know they might seem like counter-intuitive, but in reality, it is much better to have your headset or a pair of headphones resting on a proper stand rather than just lying on the table.
What Is the Best Headphone Stand?
The best headset holders let you safely stash your headphones when not in use, while freeing up space on your desk or table. These mounts or stands work for both wired and wireless headphones, in addition to video-conferencing and phone headsets too.
3 Important Factors You Should Look at When Buying a Headphone Stand

What microphone is best for Asmr in 2020
If you’ve ever watched an ASMR video, chances are good you’ve seen a 3D microphone used to create countless tingles. Over the years, hundreds of ASMR artists have turned to 3D recording earphones to create some of the best ASMR videos on the internet.

What Is Asmr ?
The term ASMR stands for Autonomous Sensory Meridian Response which those who experience it often described a tingling, static-like sensation that refers to a relaxing, often soothing feeling which spreads from the scalp and moves down the back of the neck and upper spine. That stimulus could be anything, but over the past few years, a subculture has developed around YouTube videos and their growing popularity.
How do ASMR videos work?
According to an ASMR study from the University of Sheffield and Manchester Metropolitan University, the videos are often used to fall asleep, relax or relieve stress.
Dr. Poerio said: “Our studies show that ASMR videos do indeed have the relaxing effect anecdotally reported...

Advice on a different dac or a dac/amp connection?
I am pretty new to headphones and recently have kind of jumped in a little more then i had planned.
My question is, what is the best way to Hock up a computer to run hi res audio files from my computer to a Dac or Dac combo that will also have an output to my Kef eggs as well as a connection to kef LSX in the future. the speakers have an toslink connection, usb connection as well as Bluetooth but no analog inputs. which ever Dac I also need a connection to an amp.
Currently my headphones consist of Sunchaser hd6xx, fostex t60rp and I would like to add some Focal clear in the future.
With those in mind and a budget of roughly 2k what would be the preferred equipment and the ideal connections?
thanks in advance!

- Ultra-low distortion AAA™ circuit with high-voltage swing
- Ultra-low noise THX architecture (less than 1 uV of output noise)
- Power to drive demanding headphones with ease (Up to 2000 mW at 32 Ohms, 1000 mW at 16 Ohms, and 275 mW at 300 Ohms)
- 3-position gain switch (allows for fine-tuning of signal-to-noise with any headphone or IEM)
- Ultra-low noise pre-amplifier output (Use the ONE to drive active desktop speakers or a dedicated power amplifier in a home stereo setup, and easily switch between headphone-out and pre-out with a dedicated button)
- High-quality aluminium chassis (which also works to shield the electronics from RF and other external noise)
- $199 MSRP Target
We can’t wait to bring this amp to market. Stay tuned for more updates in the coming weeks—and as always, if you have any questions or comments, leave them below. Best, The Drop Team
