2 comparisons were made today:

system 1: Sony DVD player-->DAC-->EVA2-->quad 306-->tannoy eclipse
system 2: sony dvd player...>DAC-->Supratek cortese-->quad306-->tannoy eclipse

Although the EVA2 sounded pretty good the cortese won without breaking into a sweat!

The output impedance of the DAC should be fine but the quad306 has a 20kohm input impedance...matching wise it wasn't the best the EVA2 would had liked.

Wish there was a Lightspeed that I could try....

Comparing with Pass B1, Eva2 is more detailed, more neutral, very convenient with the remote control. While B1 is more Hi-Fi, warmer sound.

my apologies for wrong information below, Eva III will not be rolled out any time soon as per the manufacturer.

CKL2,

Wow, you must be their top buyer!
Kok had just told me there are 2 EVA2 users in HK.
You should perhaps write to him as he is very eager to know if you like it.

Wondered if upgrading the caps would help improve the resolution....I have the B1 and DCB1 boards but yet to get the parts to assemble them. Hope to do that soon : )

Hi pluto2,

I am lazy. I just ordered those recommended by Mr. Pass in the pdf file.

Good to know : )
So CKL2 what kind of coupling caps do you use in your B1?

Hi scallywag,

Source: USB Monica + mojo + many power upgrades
Power Amp: Charlize 2 + PH's power regulator
Speakers: DCA4 fullrange with subwoofer

Yes, it is always on. I don't know about EVA3!

I think the advantage of LDR is details, details, details.

Hi CKL2,

May I ask what are the sources/poweramp+speakers do you use? I wonder if you had achieved a good impedance match with the EVA.
Would you know how long the unit takes to warm-up?
Do you leave the unit switched-on all the time?

BTW, I got an email from Kok on 3rd/Jan about the new stock of EVA2 but I've learnt they have an EVA3 in the pipeline so I'm waiting for the that.

You might be the 1st EVA user in HK!

My Eva2 is received. Comparing with my PassDIY B1:

- width of soundstage is similar
- depth of soundstage is deeper
- more details

I changed the bundled 12V/1A SMPS to a DIY regulated PS. It is very convenient to have the Apple remote control:

- +/- volume, 0 to 23, 24 steps
- 3 inputs
- mute/play button
- display off to further reduce noise

Hi pluto2,

Not yet received! Should be a good buy from what I have read.

Just order the 'Eva 2'. An LDR preamp with 3-input! It is around $2.8k with shipping.

I bet the response of the LDRs to light actually generates some kind of even harmonics to the signal and that kind of distortion makes music program sound more europhic to human ears, very much like carbon composite resistors do...in fact, the distortion is reported to be up to a 2 digit figure :P

though that still cost less than a pair of PEC pots anyways.....

ah! it is not a fair comparison. you still need the ancillary stuff to make it into a pot^-^

No problem Not-So-GoodSamaritan : )

But you are right, they will be at a premium, though that still cost less than a pair of PEC pots anyways.....

i think i've misled you. i didn't buy from that guy. silonex claimed to have ldr sorted and you can buy them. i was referring to these.

the manufacturer will claim they are matched and with tight tolerance until it is tested...the diyaudio thread is a long read...
