Hey guys, I got my 789 today,
i prob won’t be using it for some time bc I don’t have a dac yet.
But one thing I was wondering which i noticed right away is that the power button doesn’t click, it just presses and returns to its place as if u didn’t press it (unlike the input button which when pressed, stays in place and when u press again, it returns to original state.)
is this the way it’s meant to be, or I have a defected device that the power button isn’t functioning properly??
How you describe it is correct. No fault.
Ok, thank u for the reply!!
btw I was also wondering why there was no cables with the amplifier.
u see, I’m totally new to this game, I never had a amp or dac before (I plan on getting the d70) so I have no idea how things are meant to be, what cables come with what or if I evan have to buy cables Separately.
maybe if u could shed some light on the situation, it would be very much appreciated!!!
You should have the power brick and cable in the box and that’s it.
I’ve no idea as to what cables will come with the D70 but it will have the power again and probably a USB cable. Usually the optical, coaxial, RCA and XLR 3 will not be included.
If you're using a PC then it should come with that USB cable. If you’re using a PC with optical output or CD player or games console etc then you need to purchase a optical cable.
To connect the DAC to the amplifier you need RCA and/or XLR3 x2 as more often than not they are sold as singles unlike RCA which are almost universally per pair. Amazon has all you need for fairly cheaply and good quality, the amazon basics range.
If you have an RCA to RCA cable or a 3.5mm headphone jack to RCA cable then you can use the amplifier anyway now until you get a DAC if whatever you are intending to use has the RCA or 3.5mm output.
A DAC will be an upgrade and be much better but at least we may be able to get you up and running in the short term.
the only cable included is the power cord lol. you have to get cables separately. a pair of balanced xlr cable(interconnect). most DACs come with usb cable so that settles your connection to source, unless you want to go spdif then you'd have to get those yourself. and of course balanced headphone cables because why not.
Ya, it amuses me how a 400 dollar amp (plus tax) doesn’t include cables!!
It’s like the way iPhone wouldn’t include for the past phones the fast charging power brick.
a bit crazy considering the fact that your paying 1000+ dollars!!
Wow, very clear and detailed!!
Btw I don’t have a PC/laptop yet.
i only have a smartphone.
is it possible to use the smartphone as a source for the dac and amp??
Yes absolutely. There is multiple ways. But it depends on which smartphone?
As you previously mentioned Apple buy yourself a apple CCK3 kit (Camera Connection Kit USB3) to lightning out then USB cable into the DAC you don’t have.
If your our smart phone has a headphone socket then buy a 3.5mm headphone jack to RCA cable and plug straight into the amplifier.
You could use a portable DAC/Amp, it would go phone into DAC/Amp via USB/OTG then output from line out into amplifier.
You could use use a cheap Bluetooth transmitter which has a 3.5mm headphone output into amplifier with a 3.5mm to RCA cable.
What audio things do you do you have if any and what smartphone or tablet or CD or TV?
I’m sorry, I didn’t fully understand paragraph #4, can u plz clarify??
I have a iPhone se (it has a headphone jack)
that’s all I have at the moment.
I use an iPhone SE. Buy a 3.5mm to RCA cable and use it that way until you get a DAC. If you wish to use it wirelessly then buy a cheap Bluetooth receiver and use the same cable as above. Both scenarios put your iPhone volume on maximum and control the volume on the amplifier.
The portable DAC/Amp was a better solution than just using an iPhone alone but if you don’t have one then it’s irrelevant but something like the Fiio Q1 mark ii as an example but there are many many more.
Btw I always wondered, do u need to feed the dac FLAC/lossless files or you can feed it garbage and it’ll clean up the music and make it sound lossless??
It’s not that simple to be honest. All aspects of a system need accounting for which will make the outcome good or bad.
Im almost exclusively streaming YouTube into Grace SDAC-B into 789 and various headphones and IEM’s. I still get exactly what I’m looking to hear but the quality varies due to it being YouTube.
The DAC doesn’t clean anything up it just converts the 1’s and 0’s digital signal into an analogue voltage that an amplifier can amplify that voltage.
Starting out with a high resolution file like FLAC is always better than lower resolution but lower can still be good just the same as you can have bad high resolution files.
Because you have the 789 which completely gets out of the way and doesn’t colour the sound it will show you instantly how good or bad your signal is.
Then its its down to your headphones, they may colour the sound and disguise any garbage problems.
People always think the the more I spend the better it’s going to get, which is true but it also polarises to opposites, the good gets way better and the bad gets way worse.
Using your iphone straight into the The amp will work fine but far from working the amp to its potential inputting 1 volt line level from the phone.
A standard line level is 2 volt from DAC’s.
Then a balanced line one level is 4 volts.
The amplifier is taking the line level voltage and multiplying that out to your headphones.
The amp amp has less work to do the higher the input voltage so it needs less gain and keeps things cleaner but it still won’t clean up garbage it just amplified it less as the DAC has already amplified it in the analogue section of the DAC.
So the cleaner the original signal file file the better the outcome, you can’t ever get rid of garbage if starting with garbage.
Aha, very interesting!!!
i didn’t fully get the whole 1, 2, 4 volts situation but it’s fine, I don’t wanna drive u crazy 😂
So if you’re using the iPhone SE, do u have FLAC files on it?
or better said, can u get FLAC/lossless on it?
Bc is so, then I guess iPhone, 789 and d70 is end game for me 🤓
More voltage ultimately means more volume.
An iphone pits out 1 volt through its headphone jack.
A DAC puts out 2volt through RCA.
A DAC puts out 4 volt through XLR 3 balanced.
Oh, ok now I get it, Ty!!
so that’s what everyone means when they say balanced give more power..
I rarely use my iPhone to play music and I don’t have any FLAC files on my phone or PC. If I use my iPhone for music I’m using a Fiio Q1 mark ii DAC/Amp and I don’t then care for the ultimate experience for what I’m doing I just want a decent sound that doesn’t sound garbage when streaming.
You can get FLAC on it but I’ve never gone down that road to do it. You’re going to run out of room pretty quickly for storage though too and need a PC to transfer them. You can stream hi res files by subscribing. Apple use ALAC I think for their hi res which is FLAC comparable.
If that hat is your end game which will be a really good set up you need to buy the Apple camera connection kit 3.
It will go
iphone into CCK via lightning.
The supplied USB cable you will get with the D70 will plug into the CCK and into the D70.
Then you need either or both a RCA cable and XLR3 balanced cables.
Then headphone dependent XLR 4 headphone cable.
You can also hook up to the DAC so many other sources in the future too so you have room to grow into the system more. Like Powered speakers too.
Decent DAC and amp to play everything cleanly then different headphones will be the biggest noticeable changes to your sound.
“so that’s what everyone means when they say balanced give more power..”
yes and no. A balanced DAC more power is supplying more voltage to the amp so it has more initially to amplify and then it will also clean up an cable interference ground loop if you have any, this does not mean the DAC is cleaning up garbage.
Then a balanced amp output has usually twice twice to quadruple the amount of power depending on amplifier topology used. Twice the voltage quadruple the wattage or something like that.
What about Spotify?
Also, is there tidal for iPhones too??
All the mainstream services are available for the iPhone but again I don’t use them.
1. The music I listen to is hard to find on them so I use soundcloud and Mixcloud.
2. I don’t subscribe to them because I don’t find them good value for money. I expect the quality to improve and it doesn’t. As I said you can have poor high quality and also I rarely need that high quality files for the times I listen to those services. I honestly find YouTube far more capable which makes zero sense.
Very interesting, so u say YouTube is good?
I feel you’re asking me regarding the paid subscription service to YouTube music which if so I also do not subscribe to it and I’ve no idea if they advertise it as an upgrade in quality.
What i I am saying is what I consume and how I consume it for me YouTube works great. It’s not perfect and I’m aware of its flaws and I’m fine with it. In years gone by I was an obsessive audiophile always looking for the next thing to make the audio great so much that I lost the love of actually listening to music.
I wasn’t. I see why u would think so.
i was asking more like a wonder..
Btw u mentioned sound cloud before, is that a music source like Spotify or tidal?
It’s no problem either way, I was thinking whilst typing wondering how to answer you so I covered all bases in the end lol.
Btw u mentioned sound cloud before, is that a music source like Spotify or tidal?
Aha, and 1)does it have lots of stuff like Spotify?
2) can I get it on iPhone?
Lots of stuff but not like Spotify, it’s more of a user upload style of service rather than a music store style of service.
Yes it works on iPhone.
When u say “camera connection kit 3” are u referring to the lighting to usb 3 Camera adapter?
Bc that’s what comes up on Apple.com when I search for a cck
