Topping E30 power supply

• • Share

okay, small class d amp can run on battery

Some say they can hear diffrence between different digital cable or speakercable, som say a linear power supplyis better than a switching power supply [hear a sonic difference ?]

I have no idea if i can hear a diffrence between a power bank, a cheap power supply and the cable in a usb 3 port mabye with my audioquest jitterbug

I guess the 5v power from a usb is to avoid a big power supply when using it with a tv or laptop,evenwhen it sounds better with a real power supply, power bank,it's still fare superior than the chip in the tv,laptop

I use a little battery pack to run my class t amp and my bantam stealth amp [ 10 AA batteries in a block ] it works very well..lasts two day or so before recharging, sounds a lot better than the supplied power supply in my opinion

I think that a battery should be adequate for powering a solid state DAC.

I wouldn't use one for an amplifier, at least not a Class A or AB.

Out of interest Tuga, with the new Tesla-style home banks, andas more folk go solar/hybrid or all off grid, do you think we will start getting cleaner feeds for our boxes?

From what I read, the grid is not prepared [an understatement] to respond to / cope with the needs set by the Government's targets. We may end up having to store our energy.

Im all in favour of home stores. For sure UK govt not prepared. But was looking at solar/battery LG/Samsung/Tesla propositions with grid isolated. Am just thinking aloud if, in that event, our domestic leccy feeds from lithium cells, gets cleanerfor hi fi etc.

You justneed a bigger battery for class a and a/b amps

Sharper filters - more ringing, less alias, less high-frequency roll-off

Slower filters - less ringing, more alias, more high-frequency roll-off

Super slow filter - almost filterless [quasi-NOS]

Low dispersion filter - no idea

.

Edit: I have just realised that the name Sharp/Slow refers to the level of high-frequency rolll-off.

F-4 sounds best in mykitchen system. The E30 is going into iLoud Micro Monitors which are quite bright in upper mid ranges. Its a big improvement on the FiiO Taishan, or the OEM SBT.

On a Samsung TV>optical>E30>RCA >Audioengine A5 powered speakers, the sharper filters sounds better. A5s quite smooth and polite in character, so this makes sense.

Thepseudo NOS F5 was least appealing in either setting.

No measurements were taken. At this end of the market fun factor and VFM are the arbiters for me. E30 scores highly on both.

It seems like the F-4 produces the best measurements too.

Thank God for that. I shall now sleep OK tonight knowing Amir has applied his tools to my box....

Replyto the video: I have the e30, it's very picky when it comes to with what you power it, simple laptop power or back of a pc is a no go, phone chargers improve sound but the soundstage is small, power bank opens up soundstage and gives more bass, this dac needs linear power supply to get 100% out of it.

To me the mo sound noticeable better

If i can finde something like this linear poiweer supply from a european store, would itbe superior to a usb port on a pc,battery and a cheappower supply

How are Audiophonics regarding delivering to the UK, delays and VAT wise, anyone know? Aren't Chinese linear power supplies notoriously underpowered?
