OK. The d50 iii is connected to the L70 through the balanced output. 1st I thought it was my cables. I had my xlr cables connected to a trs adapters. I then purchased custom trs ended to xlr cables. No change in sound output. I went into the menu of the d50 iii to make sure it was set to 5v output and it was. The L70 is set to high gain. So where am I misconfigured? Again it runs everything else to high levels of sound, but the he6se v2 is very low.

Again, use a basic multimeter to check that you're getting the expected voltages out of the D50III and L70.

If voltages are low, then you have a volume-related bottleneck somewhere. Could be in the OS, the player software, the Topping settings, or perhaps a defective cable between DAC and Amp.

If voltages are high but volume is low, then something is wrong with your HE6. Could be the cable, the internal wiring, or the drivers themselves.

Side note: I know the he6se v2 is in working order because a friend of mine brought me the topping pa5 with his cables and it was great. They sounded wonderful and powerful but he stated that for prolonged use he would recommend me getting the adapter from hifiman.

The PA5 can play the HE6se about 25% louder than the L70.

If you're experiencing a drastically higher delta, then something is wrong.

I also use my he6se v2 with the L70 and I get enough volume with both RCA (2V) and XLR (4V).
Do you have to turn the L70 up to the maximum and it still isn't enough?

Which adapter or cable do you mean exactly? Can you please post a link?

I would like a amp to drive the he6se v2. The L70 cant. I start getting sound at -8.0 db and thats about it.

How much more do you have to turn up the volume compared to your other cans? The HE6 family is rather notorious (requring almost 12 dB more than a Sundara would be expected) but nothing much below -8 dB at high gain does sound a bit extreme.

Which output on the L70 are you using? The balanced one with a corresponding headphone cable, hopefully? Using that it should go pretty much exactly as loud as the PA5 (gain ~20 dB each, 52 vs. 55 Vpp max).

Are you able to conduct any electrical measurements (resistance and voltage)? Do you have access to an electrical multimeter?

I don't have 1 but I can get 1 from harbor freight.

Yes I have to turn the L70 all the way up to get sounds, don't have to do it with my other headphones.

I'm using the balanced output. I have 4.4mm and XLR cables for the he6se v2

I meant the adapter for the PA5 and the he6se V2

Get one. If you can afford a HE6se, you surely can find some spare some money for a multimeter It is something every household should have.

While you are at it, make sure you also have appropriate sized metal pins/wires you can poke into the connector sockets to make electrical contact for measurements. Alligator test leads are helpful too.

In this case, the DAC output can be probed from the XLR end of the TRS->XLR cable and the L70 output can be probed from the headphone end of the HE6 cable, with the HE6 disconnected.

That makes the outputs accessible enough to where the standard probes that come in the box should be just fine.

Thank you. I will do this and get back to you guys with an update

If mattress has a standard scale rating of 1 thru 10 1 being the cloud soft to 10 concrete floor.. Now if the audio HiFI world could adapt a standard scale like mattress i think it would help not only new people but everyone else ..the scale would be 1 being extremely warm... 5 being neutral....10 sterile,analytical.

For people experienced with measurements, there are words that roughly correspond to certain measurable phenomena (below). The real problem with this is it would force the audio companies to acknowledge that they are either transparent or not transparent and measurements matter. The whole game of not showing measurements has been to try to have their cake and eat it too - to be "more accurate" while being...less accurate, as opposed to catering to an inaccurate preference, or just being inaccurate to be a little different and charge more. Or even just being accurate and claiming it's different. The whole dial-a-mattress thing would give up the grift.

To measure output voltage, play the 60Hz 0dBFS test file (attached below) on repeat, then set the multimeter to V AC and probe between Hot and Cold (Balanced) or Signal and Ground (single-ended).

It does not matter which probe goes to which of the two contacts.

On the XLR plug, you want to measure between Pins 2 and 3:


On the HE6 cable, you want to measure between Tip and Sleeve:

That is awesome!

ok based on the graph I would say that Like the L70 with a bass bump. (I listen to 1. Movies & TV, 2. games, 3. music. in that order) But the topping tune eq sounds horrible to me. APO makes it clip too much Any suggestions

If APO causes clipping then it's again misconfigured.

Make sure that Peak gain is <0dB, or <-1dB for some extra margin.


Preamplification must be at the top of your effects chain.

 

[ahofer]

That is awesome!

BTW, that dip in the presence range (2khz-4khz) is often the source of 'warmer'. Or a more steeply rolled-off house curve.

What is your favorite house curve

Who uses DSP in their two channel or multichannel set up? How do you like to set up your house curve?

Thanks that fixed it! Mine was set to 10 but i dont know why. I reset it to 0 like you said but it kept going back to 10. I uninstalled it and re-installed it and its fixed. no clipping!

What is your Peak gain according to APO with Pre set to 0?

Make sure to reduce the Pre, even to less than 0, until Peak gain is below 0.

its 2.7 right now after EQ
