    <sigh>

    As @HitmanFluffy intimated, you are not yet qualified to triangulate and calibrate your impressions to others'. That is until you have more experience with higher-end gear, more non-shitty gear, and have impressions with a correlation factor > 0.63 to established members. There at least needs to be some common ground. This is why we don't have links to 17 random reviews of random gear from random f**kers on the home page.

    Now you do realize that there are underground protectors of SBAF (banished because they were unenlightened and deemed unsuitable for the more delicate sensibilities of 2017). I don't keep tabs on them, but somehow I hear their screams.

    I had a few hours today and worked this up for you. The output probes attach to any exposed skin. Don't press the power switch for too long though.

    Hahaha

    I'd love to hear this amp, but have no need for it. I prefer the BHC warmfag sound anyway. :p

    The draw for me is the DAC and other possible peripherals in the same chassis/form factor concept. If this can become a complimentary and inexpensive component system (like Schiit products) all from various boutique makers, as an alternative to the Schiit sound, then I'd be in. Wouldn't that be fun? I think so.

    :punk:

    Schiit is finally getting some competition. This is good thing.

    There’s a beta program? Man, that sounds easier than the way I churn gear.

    Nah, there isn't one. I made that up to simplify saying "MD selected some individuals to send their products to for evaluation and feedbacks." Admittedly, I have gotten lucky a few times but luck doesn't work all the time. Plus it doesn't afford me more experience and expertise, which are necessary for more critical listening feedbacks.

    As a big fan/supporter of Cavalli who has a LAu as my main headphone amp I am drawn to buying one of these. Heck, it costs what the tax on my Liquid Gold would have been if I'd bought it instate (and at full-price). But then again, do I need it? Is that even a consideration? Don't think so. ;)

    Ha! Great point. Thanks

    PS - Just looked at the MD page - "1779 users have requested this product", so if even half of those end up buying it, that's a pretty decent response in my book.

    No need to get it unless you need it. If it's a good amp and sells well, it will come back on MassDrop. That's how they may back their R&D and manufacturing start up cost: volume.

    Plus, in a few years, MD drop will open a store across the street from the shttr with stock on hand!

    How does this compare to Liquid Carbon? I think people here don't really like the Liquid Carbon.

    One uses a tube, the other doesn't. Perhaps more succinct questions will get you father.

    I want to ask how does the MCTH compare with LC in sound using se out with LC. I'm curious because cavalli gear seem to be favoured here although they're very pricey but not the LC.

    I think you can put two and two together. Read the first page and impressions in this thread and then search for Liquid Carbon, which has been talked about ad nauseum and the general consensus is the LC is a poor performer especially for the price.

    thanks but unfortunately I haven't been able to understand all those terms used in those comments yet. I kinda wanted someone can answer my question with a shorter and more direct summary :(

    Understood. But you didn't just ask one question that could be (briefly) answered...
    Given that the MCTH almost certainly won't be available for a few months following its Drop, I'd recommend that you pick up a Magni/Modi 2U stack and see how you like it. Or spring for the Vali 2, if you want to spend a bit more for a better amp. Those components offer the best bang for their buck of what you listed.

    Assuming you're relatively new to the hobby, I'd give the MCTH a miss. It's likely to be overkill and you might end up regretting the purchase, especially given the considerable delay between the Drop and actual shipment.

    What headphones?
    1. Buy Modi Multibit and Vali 2 now. This establishes a reference point for everybody here to help you.
    2. If system is too bassy or you want more sparkle, clearer and energetic sound, then in several months, buy a used MTCH or wait until the next drop.
    It's generally too hard to us to make recommendations to newbies. Price performance ratio is good across the board for everything you mentioned, but ultimately it's useless if you don't like the sound. Whether the MCTH has a PPR of 1.93 or 1.73 compared to 1.83 doesn't matter. Generally, if something is shit, we will tell you it's shit, or we won't overtly talk about it, unless there is a direct question, or a direct challenge from a noob.

    Those with more experience with designing LPS's than me, please correct me if I'm wrong.

    28V @ 1.25 A means a transformer that is rated for at least 30 V (if you want to design on the edge) to 36 V with >=2.5 A continuous. So, at least a 100 VA part with correct secondary voltage. optimally 24 Vrms and at least 80 VA (100 VA would be better for better regulation). EDIT: Thanks @Cspirou for correcting my error!

    A voltage regulator that has a Vout-max >=33V and can handle 3A

    Be very careful of the mains going into the transformer. You do so at your own risk as electricity from the wall can be dangerous.

    Read the application notes on the regulator for how to make a suitable circuit. Adjust the bulk and filter capacitance to your liking. Add in a suitable bridge rectifier (>3.5 A). Slap a heatsink on the voltage regulator and maybe the rectifier if you are close to the amp rating. You probably should add an in-rush current limiter (an appropriate NTC thermistor) and a slow-blow fuse as a partial safety measures to protect this ~$100 DIY project.

    More advanced designs should include EMI filtering or by adding a power entry module that includes a plug, an on/off switch, EMI filtering and a fuse.

    Happy building!
