Why do the reviews say this costs $250? Did they raise the price because of some update?
I wonder what this sounds like with Schiit LISST tubes? Has anyone tried it? And how does it compare to LCX?
Am I able to use it in UK where the voltage is 220v
In my opinion, (unless my unit is faulty in which case all i'm writing is null and void), while the CTH amp has decent bloom and pleasant natural tone, but it lacks in power to properly drive a fairly efficient planar megnetic like the HFM Sundara, its bass lacks good impact and no dynamics on headroom (peaks, macrodynamics, etc) leaving you wanting, the Headphone section of the iFi Audio Stereo 50 (an all in one) drives it much better with more aplomb and better bass control. I didn't want to use an all in one for this purpose, as it is a waste of tubes, etc. etc. The IFi I have here now is a loaner from a friend. What a nice piece this iFi is!!! for the money it really kicks butt and uses EL34 tubes for the output which is a very nice sounding power tube for efficient speakers, etc.

You might've got a bad amp. If you read the reviews, people say it pairs/runs well with their planers like the HE560 or HE4XX. Before returning it, I would suggest burning in the tube (20-ish hours) before returning it just to make sure it isn't the tube itself.

Thank you for your suggestion, I’ve already tried that. i need to find out a customer service to return this product.
With the HiFiMan Sundara it seems not be be able to drive it to fully open up, even though Sundara is a 95dB/mW medium efficient with a 37 Ohm impedance load, maybe my CTH+S is faulty??
Reaching out to the community- What is everyone’s thoughts on this amp vs, say a Schiit Vali 2, xDuoo TA-02, or Cayin H1-A1? I own the TA-02 with Mullard tubes, about to pull the trigger on this amp. I also have my eyes on the CTH without DAC and China LPS for about $200USD after JPY conversion. My dynamic cans: HD58X and Blue Sadie My planars: HE4XX, Oppo Pm-3, and Blue Ella I also have a Topping D30 and MDO2. I want that sweet tube sound and enough power for my planars. I heard the Cayin already and it is amazing. I feel like I’m missing out with my TA-02.
was working perfectly for a month. now suddenly there is no sound coming out of the right side of my headphones - only left side has sound. when i plugged the headphones directly to the PC headphone jack i get sound from both sides so its not the headphones. i tried plugging the cth sdac into different usb ports behind and still get sound only out of 1 side. i checked all my sound settings also and there are no balance issues. my headphones (hd600) are connected to the front of the cth sdac via the 1/4 jack. it was working perfectly fine before, i don't understand why this would suddenly happen - anyone have any suggestions to fix this? And should i be reaching out to support and would they be able to help? This is my first massdrop purchase and this is pretty disappointing if its a problem with the unit
Can the tube be broken by hitting it?
danimeisteR
yes if you hit a tube it breaks
danimeisteR
Almost everything can be broken if you hit hard enough O_o
How does this compare to the other Massdrop Amps like the LCX or the THX 789?
Hi Everyone, The Massdrop CTH + SDAC DAC/Amps are on their way to our warehouse in New Jersey! Once they arrive they will go through receiving and quality control checks. We are on track to meet our estimated ship date of February 27. We are looking forward to everyone receiving the first production of the Massdrop CTH + SDAC DAC/Amp!

Better...versus what?
This compared to, say, the included dongle with my Pixel 2 is a massive difference. It's a lot better than my iPad's headphone jack too. Versus my old DragonFly Red? This is clearly better, but it's up to you to say if it's worth the price. My opinion is that the synergy between the HD6XX and this piece of kit is excellent and sounds great, but I you kinda have to give me a reference point to start with.
So...short answer is...yes, it's worth it?
AveryC
Can the CTH work with the additional filament current of an E80CC tube?
I am looking to pair this with the svs ultra bookshelf speakers to my computer setup. Will would recommend this ?
served1
Hi Served1; do you realize this is a headphone amplifier? How do you plan to get sound to your speakers?
Gonza
You really need an "amplifier", not a headphone amplifier . . . they sell some nice units out there and even here for that purpose
I would like to buy this, but I am wondering if it will work plugged into my USB type C Samsung smartphone. Does this pair well with Android or is it intended only for computers/laptops?
Jaagar
Please advise - is this compatible with USB type C Android devices??
Hey @CEE_TEE , will the CTH be offered sans Dac anytime soon? Same goes for the Liquid Cavalli. Lately it seems that the Sdac is always included. Is that where the demand is going?
comparing this MCTH+SDAC to Schiit Mjolnir 2 (got a fairly new and used, price offer is quite tempting), which should i take?
how much power can be given in 50 ,300 and 600 ohms
Azeendeen
All they advertise is the 50ohm 1W, which is on the balanced output because it designates per channel.
jm090
Yeah I saw that. But Is it possible to know what it gives out per channel? I'm still an audiophile noob my bad. Cause I'm wondering if it would power the sennheiser 6xx that has 300ohm impedance if I recall. I only have the akg 7xx that has 30ohm
Anyone tested SDAC with PS4?
Got mine delivered today but looks like the amp is not working. Inserted the tube and turned the power on the red light lit up on the front and within few seconds it turned white. I connected my macbook to the micro usb and selected the computer audio output to SDAC and plugged in my headphones to the 3.5mm port on the back and I was able to hear the audio. But turning the volume knob had no effect. I connected my headphone to the front 1/4'' port and it was not emitting any sound. I toggled the input button and there was no change in the functioning the back port was behaving just like before and the front port was throwing out no sound at all. If I press the power button while connected to the front port I can hear a small beep in the headphones. Looks like no matter what i do only the SDAC is working and the amp is non functional. It would be great if someone can help me out on if I am missing out something. I removed the tube a couple of times and put it back just to check if there was something wrong in the way I was putting the tube and every time it sat in there perfectly. When I power up the amp the tube gets pretty hot, hot to the extent that I can barely hold it continuously for 10 seconds. Not sure if that is expected. Also I don't see any visual cues from the tube, I read in some review that the tube lights up when the amp is powered. This behavior looks very much like what was described https://www.massdrop.com/buy/58390/talk/2146256 but unfortunately I don't see any resolution there.

I had contacted massdrop support and they have sent a replacement and it is working fine.
Hi Everyone, I got my CTH + SDAC yesterday and plugged it into my Windows 10 PC using the supplied USB cable. The setup instructions say when "Using the CTH + SDAC DAC/Amp" on a PC, to connect the USB cable, set computer output to 'SDAC', and make sure the INPUT button is 'extended' so that the amp is connected to the internal SDAC. Then connect my Sennheiser HD 6xx headphoens and enjoy. The problem is, I don't hear anything unless I 'depress' the INPUT button.
My question is, are the setup instructions incorrect about the INPUT button needing to be extended, or is my amp not working as it should? Is anyone else using one of these on a PC and have to depress the INPUT button to hear sound?
Thanks in advance!
woodmtw
Same set up here. My button is depressed when playing from my Win 10 PC. Could just be a typo in the manual.
Defvayne
Thank you Defvayne, I too believe the instructions are backwards. All else with the unit appears to be working just fine. Appreciate the feedback!
Does this SDAC support MQA? Thanks.
anyone know how much i will actually save on this? market value - drop price? thanks in advance

thanks for the reply - this is my first ever purchase on massdrop and also my first ever DAC/AMP (i don't have alot of knowledge about these things but i do own a pair of HD600s :D) - and i do realize alot of these massdrop collabs won't have a retail price. i guess i was just wondering if the price listed for this CTH +SDAC would be considered a "steal" for a product of this "calibre". TLDR: is this worth it for the amount i'm paying or could i go elsewhere with the same amount and get something better?
momotan
I think its very competitive for what it is. I havent listened to one, but it is a well reviewed amp. I do know from experience that OTL amps benefit the 600 series Sennheisers in ways i couldnt imagine possible, they make them truly amazing headphones IMO. For this reason i would suggest looking at the darkvoice or LittleDot amps that are frequently sold here.
Can we please get the CTH AMP ONLY again?! I already have a Modi Multibit and want only the amp for $249
I am currently using HD6XX with FiiO Q1 mark2. How much improvement can I expect with this DAC/AMP?
Very weak, low-end amp. Based on specs it should at least be clean and low-distortion. Resolution should be okay, but it'll be limited in terms of dynamics. You'll need to find a linear PSU to get the most out of it.
What are the differences between this and the liquid carbon (besides the tube)? Also, which one should I go with, or should I get something else altogether?
I think i am asking too much, but if this amp is strong enough to power my argon modded t50rps(which i have already confirmed as true) and belt out some buttery mids on my 58X like a typical OTL tube amp does on 6XX series headphones i would jump all over this for an easy 2 in 1 and reduce some desk clutter. If someone can answer the latter i would be forever grateful. Currently using magni 3 + PC sound card.
jm090
You might be better of doing a Google search on that combination if you havent already. Would suck to miss the drop and wait another few months to get one.
Does anyone know how ZMF Eikon's would pair with this? Initially using single-ended but I plan on getting a balanced cable at some point.
I current use an Audio-GD NFB11.28 but wanting something I can use with tubes + balanced.
Llex
I personally dont see a reason to get this if you already have an audio-gd. You should get a full OTL with Eikons.
Getting strange static out of the right channel that doesn't seem to go away until I have the volume at a certain level or when my music drowns it out.

Mine went away, I burned it in overnight with no headphones plugged in. I just played music at close to max volume and the static went away and hasn't come back so far.
frostfiree
I'll try that tonight, thanks!
Does anyone know what are the tube replacement or upgrades for 6922EH?
LuciferSama
I switched my 6922 to an Amperex gold pin 7308. Has a richer and warmer sound compared to the 6922 that came with the unit.
LuciferSama
i dropped in a spare 12ax7 i had laying around from my mesa boogie gituar amp and it sounds pretty sweet when i'm listening to classic rock...it's a mesa tube from a mesa amp,figured why not try and use the same tube that was used to record some of these songs.
Hello - I see a lot of references to how well this unit pairs with the senn 6xx. Any experiences with how it may pair with the 58x Jubilee? Thank you
Just got mine today!!!!! Right outta the box worked awesome!!! Cant wait for the tube to get warmed up and the sound to get even sweeter!! Will update down the road to let you all know.
WAVZ
It is sounding better and better as the tube is getting used more and more. loving this combo more then I thought I would.
