Topping DX7 Pro+ Review (DAC & HP Amp)

[tensor9]

@amirm did you do a SINAD vs volume test?

 

[Shinobi]

Hi there,

Quick question, did anyone try the sound modes ? I can't hear any difference between them...

 

[Tokyo_John]

I'm trying to figure out the value of the DX7 Pro+ ... where I live (Japan) it costs about the same as what I paid for both D90*+A90, which is slightly more pricey than what I've seen the D30Pro+A30Pro stack going for (by about 20%). Of course the DX7 Pro+ is just a single unit and more compact, which has many pluses/benefits...but is it really on par with the D90*+A90? If so, does this hold up for all of the inputs/outputs options?

*Earlier version of the D90 with the AK chip w/MQA (interestingly, I've seen this older version selling used for a higher price point than the D90 SE new, in Japan...must be AK fans).

Hello
Has anyone ever listened to music files in DSD format with the DX7PRO+? I have white noise and crackling that start when I start playing DSD files. It is especially very strong with IEM. Even when I bring the volume and gain down to minimum the white noise and crackling continues until I turn off the device. I don't have this problem when I listen to files in PCM format.

Probably because the unit has a digital volume control and for DSD to work correctly the DAC needs to be in fixed mode?

Hello Snoopy.
Thank you for your answer. But what do you mean by fixed mode? Cordially

Hello Snoopy.

Fixed mode is when a DAC is at 100% output and you can't adjust the volume anymore.

Hey there, has anyone tried the dx7 pro+ with a he-6 SE V2? Would it have enough power to drive it?

 

[Pat971]

Fixed mode is when a DAC is at 100% output and you can't adjust the volume anymore.

Hello Snoopy.
would that mean that I have to use the XLR or RCA output connected to an external amplifier to use it in fixed mode? Cordially

Usually DACs with a volume knob have the option to change that In the settings.

Fixed volume output = DAC mode

Variable volume output = preamp mode

hello snoopy
So you can't listen to audio files in DSD format directly on the DAC's built-in amplifier without the annoying noises? Do we have to use an external amplifier with XLR or RCA output to listen to DSD files without noise?

 

[Pat971]

Fixed volume output = DAC mode

Variable volume output = preamp mode

Hello Overseas. Thank you for the information.

Hello Overseas
I saw the configuration in DAC mode. But it is only for use with an external amp. Do you have a trick for not having the noises by using the DAC's integrated amplifier? Thank you

There is no "trick" to do that

 

[Pat971]

Hello Overseas. Thank you for your assistance. Do you know of any DAC amplifiers that do not produce parasitic noise in the headphone output when listening to DSD files? ? Come cordially

Sorry, I have no experience with DSD. But I would suggest that a non-compatible scenario would give you breaks, interruptions. If it is continuous sound, no matter how bad, maybe it is some solution.

Every DAC that has a "fixed mode" and supports dsd

OK it's noted. Thank you very much for all this information. Best regards
