Haven't tried a turntable but I'm sure it works fine,  the preamp on the DAC 9 is excellent. I hooked up my old cd player to the RCA input and it almost felt like a new player 😀

Thank you @pewe


 One more question: Has anyone connected the phono preamplifier (+ turntable) to the analog input on the DAC-9?

Anybody else?

I have MANY NuPRIME DAC-9 customers who have done just that, and all are quite happy, and no reported issues.

What do you think which is better : nuprime dac-9 or Linn Majik Kontrol? Only as a preamp.
I'm looking at Linn because of the phono input. For my Linn Sondek LP12.

Simon

In this case you should consider HPA-9

No no...I will buy a dac-9  :) because I need a DAC too..and because XLR output for my active speakers.
I than I will buy some seperate phono for my LP12.

Hi guys,
I plan to buy official T1A fuse as backup for future.

May i know where can i get it? 

Thank you.

Can anyone please tell me at what volume level is DAC-9 at 0 gain?

Is the 99th step 0 gain? I've read somewhere its the 94th step or the 81st step. Connection to pre is via RCA, if that makes a difference.

I haven't been able to find a straight answer for this, so some clarity would be greatly appreciated.

Thanks,
Martin

volume level : 94 = 0dB=4Vrms

Good morning Rusty,

Thank you for this. Am I then to understand that volume level 47 = 2Vrms?

Best regards,
Martin

NO, it is not linear.

Ahh,

So where would 2Vrms be?

Thank you,

It's still 94

???? What? No, obviously not! 94 will give 4V Rms max, when the input is 2V Rms.  So no, 94 is NOT 2V Rms, and knowing the 2V Rms max is useful if you are looking to use the DAC to input another PRE (obviously, not bypassing the PRE functionality itself) for those PREs that have a maximum input of 2.3VRms, which is very common.  So please don't confuse people that are asking genuinely useful questions!

You are wrong. The unity gain setting for the DAC-9 is 94 for either output just like it is 93 for both outputs on the DAC-10.  The SE voltage is half of the voltage of the XLR output but it takes the same gain setting to get there. Not sure as an IDA-8 owner how you would know I was wrong.  I actually have experience with the gear in question or I don't answer or get involved.

Jack how can a volume level of 94 be both 4Vrms, and 2Vrms simultaneously?

JackD, the unity gain on the DAC-10 is 93 for the low gain setting where you get 2V in and 2V out.  At the high gain setting, at 93 vol you have 2V in and 4V out.

The fact that with the DAC-9 you don't get switchable gain, it always stays at this 'high' value.  While I agree that 94 is the value where the signal is not affected by the attenuation or volume control, there is still a 6dB (double voltage) gain.  At full 2V in, that would yield 4V out.

There are a number of devices that have a max input of 2V.  So, for those, and having a fixed gain setting, we would need to know the volume value that, while attenuating and possibly degrading ever so lightly the signal, achieve a 2V output.

And it doesn't matter at all what equipment I have to know you could be wrong, but I have DAC-10, ST-10 and uDSD.  Never have seen an Ida-8.  Not sure how that was relevant, though.

Rafa.

If we use your and mvm's logic and the unity gain setting on the DAC-10 for 2 volts is 93 on the low setting for the SE outputs then tell me what it is for the XLR outputs
on the low gain setting since the volume control only goes to 99. A simple solution to this is to use both outputs and measure with an actual SPL meter or an SPL app on your phone.  The voltage output on the DAC-9's outputs are standard. Voltage and gain are not the same things.

Jack, I wasn't arguing with you, I was asking.
To be honest I still don't actually understand how it could be the same at the same attenuation level?

Best,
M,

Changing from the SE to the XLR outputs involves changing the output voltage not the gain supplied to the outputs.  From the website product description.

"Individually adjustable volume on each input for precise level matching of sources. If DAC-9 is connected to another preamp or home theater AVP, set the volume @ 94, which is 0dB." No differentiation of outputs is listed.
