Topping L30 Headphone Amplifier Review

[JohnYang1997]

Wait a minute. Is it better to just set a higher output with E30? Like 3V?

Ah yes much better solution.

 

[3125b]

since it has digital attenuation - why not

 

[Vini darko]

You could always buy two l30's and use one as a line gain stage

 

[Atanasi]

The consumer line-level nominal voltage is -10 dbV, that is 0.316 Vrms. The nominal level is often 20 dB below full scale, so full scale at around 3 Vrms is according to the reference.

As added bonus, it will make E30 sounds "better" in audiophile world.

But then you get the other side of the crowd crying about "cheating" with a DAC that's "too hot".

I say leave well enough alone; you're dealing with the (extremely) vocal minority here. The specs are clear to anyone who cares enough to read them. I'm very happy with 3 useful ranges of gain. I think it's the first amp I've ever owned that had such.

Many of other specs won't be achieved with 2V input either. Like dynamic range etc. The whole set of specs won't look right if 2V input is a criteria.

From a technical communications perspective, that is not an insurmountable problem. It is easily addressed.

You provide three tables of data. The first table provides the specifications that don't change depending on the input. The next two tables group together these specifications for the specific input value. One table of specifications for one input. Another for the other.

John is too honest and people are too harsh on him.

@JohnYang1997 just leave L30 the way it is. If you want to change anything, change the manual with an extra footnote. Don't change the basics....

Thanks from an L30 owner.

I think we'll change the E30's output to 3V. As there's some pcb changes going on with E30, it's much more convenient and elegant to just change output level of E30.

 

[3125b]

Plus it'll appear to the subjectivists way more.
Increasing the output voltage will easily make it sound twice as good

Problem with Amazon basics RCA Male to Male is that they don't make lengths shorter than 4 feet. If they did I think it would be the default suggestion for short RCA cables.

I use these. They work fine. https://www.amazon.com/gp/product/B008UXXMHM/ref=ox_sc_act_title_1?smid=A3QWSZ44N8P3XH&psc=1

Sorry to muddy the water. Won't that make the e30 less usable as a digital preamp? If its got to go to 3v. It's going to have to ramp up volume faster so there would be bigger steps when using the volume control?

 

[3125b]

It's got 99dB attenuation ...

You can just attenuate it. No problems doing that. Variable pre-amp is included for that reason after all.

 

[Vini darko]

Using 99 steps from 0 to 2v is 0.02 increments. 0 to 3v is 0.03 increments. So the steps are bigger

 

[Vini darko]

Its not night and day just a observation

 

[3125b]

0.5dB stepping.
"Twice nothing is still noting" is all I can say to that.

 

[Vini darko]

Yeah im probably being pedantic.

Probably outside your realm of expertise but how will you handle the SKU management/documentation here. Sounds like a nightmare with existing models in the field.
