Go for Pono player, it created by Neil young and the design and engineering by Charlie hansen of Ayre Acoustic. you can find it customized to the US base band like pearl jam etc

there is a good sample about engineering wise and philosopy about human perception on sound. you can read on firstwatt website on zen i/v converter. The almighty nelson talk about how the opamp iv need to be change due to judgement from the producer ear.the result they remastered the record and...

there is alot of compact class H amp to be use to drive as piezo actuator driver like mems, they work with 3-5v like LM48580 or sonitron product. I believe this will be disrupt the iem market. just wait who will start to sell under $100 include the amp, since the driver and chip amp is worth not...

Number of the driver has nothing to do with sound quality, the more drivers, the larger your response band will be.

Konichiwa, Are you tl aka kyw ..? Thanks

I really like crinacle new rank adjusment. Good for you

Someone in fb give a clue about the closest driver. Below is the picture from itsfit lab and earbridge e70, and soon on spear lab triton, a magnetostatic driver

Yah, you might be right. The only make sense for me for this estat driver is the way electret microphone work and this driver is working almost in the similar method. But it's more to piezo than an estat.. Who know Cmiiw

No I don't own shuoer tape iem, but to be call estat or electret you need adapter to convert the signal to high voltage signal in order to move the driver diaphragm. Estat driver from Sonion use the adapter/coil to convert the signal to high v signal. From the picture of the driver breakdown...

Imho, this shuoer tape doesn't use the estat/electret driver it's hard to believe there's such technology as estat/electret inside the housing and integrated with the dd driver. It seem use the piezoelectric driver.

Hi progdvd, Thanks for your impressive comparison. Sure it help me to decide. Regards,

Sorry to hear that, it's OK tae your time.

How is your s8f compare to spring 1? Many thank in advance for your reply

Have you compare t2 to marsh hpa? Thanks

It's a qls qa361.. I always admire what qls got to their player, (fpga, cpld. Etc) start with qa360, and the qa361 escalate his old brother.

Agree, I'm button lover as well, my friend develop the teri g1 and revamp p1 dap. Not a fancy try to achieve most direct processing digital data. Scree consume most power in a player it's hard for low budget dap to sound good with display. Imho . Dac and.buffer suppose to get most power from...

Seem to be qls product or something with fpga data processing or fifo like aune

Great work, looking forward to it. Im done with ed 29689, wbfk and rab. All work in full range, no crossover the rab and wbfk spout being take off and no filter, the series config result not enough power to wbfk, i did some in pararel and series to ed. Now iam Working with ci, fed, ed and...

Seem like. Fed and ci and dtec. I doubt the fr still the same once it got in to the shell. I got bwfk and ed and take off the spout.. I like the sound without crossover just arrange in series to level the spl

This is my try to diy iem, Using rab 30233+wbfk 30095 +ed 29689 all in series.. No cross over, all driver work in fullrange The rab and wbfk being modified by take off the front sound tunnel I heard this sound balanced from. Mid bass to high Any idea to. Enhance the sound? Thanks in advance

Never thought that revamp product could reach the island.. I hope you like your p1

Just found out that the output impedance of this fella is 10.x ohm.. It might be the culprit of the love and hate of this fella

any body know the impedance of warbler prelude? how is it compare to etymotic like er4 xr? thanks

by the way, we already have dap using a tda1387 chip, you can search on revamp thread for Nuansa P1

Hi, Actualy, i am doing this converting dac chip all of my dap to tda 1387 for a long time, since i realy love the timbre sound coming from this dac. my favorite IV is using BC560 without biasing before R. the first picture is using the pot to pin 7 to control the volume and not using the IV...
