Review: ZERO 24 BIT/192KHz DAC/Headphone Amp/Pre-Amp - Page 596

There is a sensivity spec for headphones, we were discussing it in this thread.

Interesting thread. Thanx!

.

Indeed, x2!

My Senns are 600ohm, and the Zero seemed to drive them nicely... Both in terms of outright volume, and the punch needed to give them a full sound.

I wonder if the 4562s are struggling? Maybe try swapping back to the original opamps, or the LT models recommended?

Please do not misunderstand me... the comfortable listen volume with my Zero/K701 is about 10-12o'clock and the Earth/LM4562 combination sounds better to me than LT1058/LT1364/NE5532/...
The best way to describe the volume knob position/output power relation would be a logarithmic curve.

I don't remember getting over about 12:00 with any set of canz, high or low impedance on mine.

Amnesia or didn't you try?

I listen to stuff pretty loud normally. I had a LD MKV and was able to max it out. It always seemed to have a low gain level. I never felt the Zero was anemic with any canz.

I tried searching for an answer but couldn't find one. My zero blew up in a pile of smoke yesterday afternoon. I fried the transformer it appears (before the fuse popped). The outer plastic on the trasformer was burning up and the area around the toroid got really, really hot.

Is it likely to just be the transfomer or is anything downstream going to be dead. What are the voltages of the torroid and where can I get a replacement. Cheers guys.

Peete may know what the specs on the transfo are. Maybe someone here has some parts. You may find the specs on the Transfo written on it areound the side of the Toroid. Seems like if all that happened you may have some "Small Toast" elsewhere. Look over all the components with a mag glass to see if anything else burned.

Zero thread is always good for a little entertainment!

I think the trannie is a dual primary (115 + 115V) with 20-0-20, 9 + 9 V (or 12 + 12V ) secondaries with a rating of 100VA.

Give Lawrence Chan a shout via email or Snow. Either one of those guys should be able to get you one. See Curra's FAQ page for email details (of it's still listed).

Peete.

192K decoding

Has anyone tried feeding Zero 192K/24bit signal? Every time I tried it w/ SRC, Zero gave me random static and popping sound. 96K worked perfectly though. My sound card is AP192 and I'm using Bluejeans digital audio interconnect to feed SPDIF into Zero. Is it my Zero, or reset of the system?

Are you using optical spdif? I'm pretty sure only coax can do 192

Coax. AP192 does not have optical.

More to the point, is there any benefit in feeding the Zero a 192k signal? The only benefit is a measuredly imperceptibly lower noise floor.
