Watts Up...?

If can use 12v then, this easy in my situation.

Yes 12v works fine with TT2. Also, a 100W/h battery power-bank will give you over 7 hours with a TT2 whilst driving headphones. Note that if you are using a power-bank and flying, it must be under 100W/h - otherwise it will be confiscated in some Asian countries - Thailand and China are particularly hot on this. I lost one power-bank in China.

But TT2 is not meant to be portable, it is big and heavy, so if portability is essential consider the Hugo 2.

Regard Rob, M scaler can too work same? On 12v?

And main if TT2, HMS will work on that power they will play same how if use with hims native power?
Sound quality not depends on power 12v or 15v right? TT2, HMS will play same?

This last questions about change dac i think.

About TT2 what your write he not portable, well 2.5 kg (TT2) + 1 kg (power bank) for back this yet normal, in before i thinked headphones weight how Audeze LCD will hard for me, but used.

Last question about power, if voltage 12V this normal how min A need?

Or for power use standart scheme how for charge chord hugo 1 in before?

Regard Andrey.

If i right all calculated have next 100 W/8 hours = 12.5 / 12V = 1,041 A then see what 1-1.5 A in voltage 12V must enough. Yet say please, if that small power enough for normal work TT2, then way in complect have adapter 15V 4A ? If sound quality will same what with power 12V 1A, what with power 15V 4A or i not right?

Regard Rob, you write in this post https://www.head-fi.org/threads/hug...-official-thread.879425/page-53#post-14324579 what if use battery 85W/h should give 6 hours, and TT2 with HP use is 13W, then 85 Watts /6 hour work = 14.16 / 13 Watts = 1.089 A then 1A will normal for work TT2 i right?

Then say please way your sayed next, A battery pack of 85W/h or more, capable of 3A and 12 to 15v will work fine. here your sayed what for work TT2 need 3A or i not right?

Please say how right? That power bank will normal https://rombica.ru/product/neo-pro-280/ i have his, because buyed for power hugo 1.

And yet how internal defens have in TT2, he have defens on overvoltage, if connect adapter more 15V accidentally?

No protection for over voltage so it’s at your own risk, and no warranty cover either.

Regard Rob, question clear for your, with TT2 or Hugo M Scaler can use old adapter for chord hugo 1, TT2, HMS will work with this, say please?
And yet in this post https://www.head-fi.org/threads/hug...official-thread.879425/page-492#post-15248916 you sayed
(If the supply exceeds 15.5v, then the power high error will trigger, ensuring that the super caps won't get over-voltage. For the M scaler the upper range is the same at 15.5v)
Then TT 2 and HMS have internal defens on overvoltage, if by chance use not 15V voltage, but more example 19 or 20?



Regard Andrey.

@steam412: 18v and above will destroy Hugo M scaler's protection diode, rendering the unit unworkable. Since a PSU has been used that is not the one included, your warranty on the protection diode repair would be void too. The Hugo M scaler will work perfectly fine from a battery power bank set to 9 or 12v - all input voltages are converted internally to 5v, so the actual voltage does not affect the sound quality. The new Poweradd pilot pro5 looks fine, but that model exceeds 100W/h so don't get it for flights. They do a smaller capacity version which is 99W/h but so far is only available on the German Amazon website.

If you have any more questions please send me a PM. I don't want to clog up this thread with repeated questions about power for TT2 and the M scaler!

Rob, can you share your opinion about future Chord products?

I mean, the TT2 is the latest DAC and it is pretty much different from others. PSU with super-capacitors, a lot of power for headphone output and even more power in balanced mode. There are a lot of different opinions, but as a headphone listener I think this is the best Chord product so far. To me it is a first DAC which sounds better on its own and no amplifier (of any price) could further improve sound.

As far I know, TT2 became a very successful product. Are you going to develop this concept further? Next Chord flagship (DAVE2 or whatever it would be called) would be powerful as TT2, or it would be classic DAC, more like DAVE is today?

No unfortunately I can't talk about future Chord products - but I can say that Dave 2 isn't on my horizon!
I know that you can't tell about certain models. I was more interested in general vision about TT2's concept of DAC which is powerful enough to drive even the most demanding headphones. It is going to be a TT line exclusive feature?

This has probably been asked, but I plan to be on hiatus from this site for a few years so curiosity piqued.

In that timeframe, if I decide to get back into car audio with Chord products I would need some type to time alignment or time delay to position center at driver's seat.

Would this newly released 2-channel DSP work or will SQ (transparency and resolution) suffer if a DSP is in the chain?

I don't mind giving up on the idea, but being in Los Angeles; car audio is part of the culture so it's always in the back of my mind so have to ask...

@Ragnar-BY:
The situation with TT2 and headphone power is that I got fed up with complaints that Hugo 2 wasn't capable of driving some easy to drive headphones - so with TT2 I decided to use a sledgehammer to crack a nut - nobody could possibly say that TT2 couldn't drive any (non electrostatic) headphone directly. Plus, giving it more power meant that direct driving to loudspeakers became more possible.

The reality is that Dave and Hugo 2 have more than enough power to drive any headphone - except perhaps one or two very exotic models.

@AC-12:
As to DSP - no DSP today is available that is 100% transparent; so you have to balance the benefits against the losses. But I think you would be fine for car audio!

Hello Rob,

I decided to share this question on the forum as i know alot of people have experimented extensively with regards to the optical source.

So can a low cost optical source be improved upon by investing more into a higher 'quality' optical source for use with the mscaler. It has been said the mscaler diminishes the importance of the optical source as long as it is bit perfect. Even so members are going to extreme lengths to improve this part of the audio chain. Lets list some brief points that differentiate between a high cost vs low cost optical source.

Low cost optical source: By its very nature and low cost it contains a generic type clock but can be powered by a third party ultra low noise power supply. Here i am thinking of the google chromecast audio with an ifi i power 5v psu implemented especially by roon as an optical source. Assuming here optical is galvanically isolated. Cost £80. This is my current set up for roon and with good results. Roon indicates my audio stream is bit perfect.

High cost optical source: Here i'm considering the Matrix X-SPDIF 2 DDC usb to optical convertor for improving audio from my computer. This unit contains 8 core DSP in addition to a dedicated FPGA for clock management. It uses femtosecond clocks as reference for 44.1kHz sample rates in addition to an ultra low noise power supply throughout. This unit can be powered by the 5v usb bus from the pc or a third party LPS which is recommended. The cost of this unit is £350 and an additional LPS which can cost up to £450. So here a total of £800 although cheaper LPS units are available. Reviews and user feed back indicate that due to the superior clock in the Matrix the improvements in SQ as an example result in increased spatial resolution and similar incremental improvements. So not necessarily night and day here but the improvements seem to be real nonetheless. Here optical out is also galvanically isolated but 'usb in' is not. The two examples laid out above seem to be fairly typical of what one can expect from a low cost vs high cost optical source when considering improving computer audio in my case. Such DDC units however can also be used with dedicated music servers.

My question is does the mscaler benefit from investing in an improved higher cost optical source as set out above or does the mscaler with its (own internal clock?) and management of incoming signal make ineffective more expensive optical sources such as the one described above? If a benefit can be gained and considering the cost of the chord stack i would be happy to invest a bit more in an end game optical source as long as i'm not entering the area of diminishing returns. With such DDC units i would be buying blind as trying them out beforehand is not an option although there should be a returns window if i feel the unit is not worth the outlay. The process of fine tuning my TT2/HMS is very enjoyable in its own right. One final point: my imac computer does have optical out but i am hesitant in using such a noisy machine directly into the mscaler for obvious reasons even though optical is galvanically isolated.

Many thanks to Rob and all headfi members. MK.
