Thanks, I didn't expect Revamp Acoustics will have a loyalist. since my product is far from perfect mostly in the aesthetic side :grin: I'm still developing a new product, but try to manage to get a better solution for me and also for the users. Letting the user can DIY-ing like rolling opamp...

Hi, I'm sorry was inactive for a while. There is much business that I need to do in my company, so I must inactive in audio works. Actually, I was work on another audio stuff but still not finish. Some Revamp Acoustics project that still on development is G2 Audio Player (for this I'm not sure...

It's prototype of Class A portable headphone amplifier. I'm not yet to continue developing PA10.

Actually, some impression is available by user that was test Tambora in PAFI 2018 Exhibition. but mostly in facebook and in Indonesian language. @nino9 also was test Tambora, maybe can give impression here.

Update, I was post Pre-Order page in Revamp Acoustics webstore

Hi all, Sorry for slow response and if any unanswered questions in past 1 month. I March 2018, I'm busy for preparing test unit of Tambora (headphone) for PAFI 2018 (Indonesian Headphone Exhibition). I will update the info about Tambora specifications in here soon. Regards, TJ.

Let me find some information about opus, because previously I know opus is more used for voice compression. I will update any information later.

I can't say anything about that now because I also was test my #001 with V5i, and no distortion at all. If P1 user from Indonesia have problem with distortion when using V5i, please sent to me for me test and try solving that problem.

I don't have any idea for now about distortion problem. do you have another opamp for test?

Are distortion with Muses02 is happened before you put V5i ?

It's not Lemo connector, it's similar circular connector, but more used in aviation. I don't have plan to use 3.5mm, because I want to keep the headphone cup slim and compact. Because a 3.5mm female socket is long enough, I don't want to sacrifice to expanding thickness of wood cup that will...

Just want to updating the progress of Headphone project. After finalizing and choosing a driver design (80mm and 90mm version) finally I'm choosing 90mm version of driver. Currently the prototype is using Sonokeling (rosewood), but in production I also will use another type of wood. Pads...

Sorry because I'm not seeing this question before. The logo is changed for easier thru-hole cutting in products (if needed), with previous logo it only can engraved. for cutting, it will hard to keeping inner square of RA in place.:disappointed_relieved:

The development on hold, but will still continue after Planar Magnetic Headphone project is finish. It's hold because I need to very take care about hardware design to support every type of DAC Chip. Also I need take care about enclosure, the mechanical thing need extra development to support...

Actually it's locked because it's just pause for a while then back to play. If not pausing you will get stuttered playback, so better I'm pausing that for a while. And I think play button will not very sensitive to accidentally pressed than other 4 button.

I was adding lock function by holding play button about 1 second until led white blinking. For who want to test this beta firmware can be download from this link: https://revampacoustics.com/files/P1/P1_V2.0.6b.zip

just a short video, showing prototype driver of upcoming planar magnetic headphone : https://www.instagram.com/p/BazX3dpgoLV/

It's bigger than that :-D For me, the power of A1 is not so effective when paired with P1 to drive midrange impedance planar like HE-4xx or HE-5xx. I use P1 direct to drive Monolith M1060, and the impedance it simillar with HE-560. But for sonic quality of course will be refined when using A1...

Last batch Nuansa P1 is only 2pcs again in stock. When it sold out, I will not to start a new batch again for a while. Because I need my time to developing a new line of Revamp Acoustics product. Not a new Amp, DAC or DAP. maybe you can guess what is that? Regards, TJ.
