Fidelizer Mod accepts modding your unit now!

 in News

Chord Mojo - Fidelizer Signature Mod

 

Back then we used to have screen issues with early DX200 units which can be a complicated case to handle with Fidelizer Mod. I resolved this case by offering Fidelizer Mod with a new unit to minimize the risks of getting defective screen while applying Fidelizer Mod to DX200.

Since DX200 has defective touch screen issue resolved and most units got their screen fixed, I’m ready to officially accept products from customers to apply Fidelizer Mod. You can order Fidelizer Mod product from website and I’ll send shipping information after receiving your order.

Aside from Fiio X5iii, iBasso DX200 and Chord Mojo, I also modify all other units. Here’s what I’ve done and going to do since last two months.

I also heard from clients about DAP getting a shorter life-cycle so it might be better idea to switch to a new DAP rather than modding. I’ve been on this journey since early days of iPod and iRiver (which became Astell & Kern) so I’d like to share some thoughts based on my experience.

 

Fidelizer Mod - Emm Labs

 

Getting a new DAP doesn’t mean it’ll always improve sound quality. Sometimes it’s more like getting a different flavor with different DAC chip or parts that cost about the same. You’ll see some audiophiles preferring older models from time to time.

You can upgrade your DAP with good reasons such as it has new features that benefits you like adding balanced headphone, full Android platform with streaming support, design looks cool and you like it. Go ahead. Take it and enjoy it. No harm no foul to buy what we like.

However, selling and buying a new ones will probably cost you over $100 up to $300 per upgrade. Using that budget to modify your product for real improvements might not sound bad for some devices like Fiio X5iii and iBasso DX200.  They’re decent models packed with lots of features and can be improved a lot with Fidelizer Mod. 🙂

Fidelizer - Black Friday

 

Last year, some people asked me why Fidelizer didn’t make any Black Friday campaign and I was like…..What is Black Friday? No kidding. I’m not into shopping and never bother with discount campaigns before so I didn’t know about Black Friday until they asked me last year.

But today is different. I did my homework so I’m aware of Black Friday event now. It’s a good event to celebrate after thanksgiving. We came so far to this day and age where every race and nation can join hands and dine together.

So Fidelizer would love to participate such eventful day also to celebrate this happy moment with discounts applied for every merchandise starting from $5 up to $200 USD including Fidelizer’s Nimitra Computer Audio Server, Nikola Linear Power Supply, and Portable Products too.

 

Fidelizer Plus: US $39.95 —> $34.95

If you send your products for applying Fidelizer Mod, I can deduct from MSRP price with discount applied. Other products outside featured Fidelizer Mod like AK380Cu, Chord Hugo TT, etc. can be sent too with special Fidelizer Mod offers from me.

DX200 - Fidelizer Ultimate Mod

 

Here’s another feedback today from iBasso DX200 customer in Thailand. He shared his public feedback in forums and also share me his private feedback to some people as below.

I modified both device and Amp module (which has soft mute circuit bypassed for better sound than not to)

I can say that this one can go up all the way in the same level as SP1000cu/ss only that the house sound is not the same character.

SP1000 both version sound more edgy and meatier than my mod DX200 which makes vocal sound more like a real person in some recording but it make some song sound weird and SP1000 both version is better in layering in depth axis but not much better. Other than that, DX200 with Fidelizer Ultimate Mod is equal to both SP1000 and beat them in some category.

Modded DX200 has wider soundstage, more reference sound and also more musical than before modding. You’ll feel how the recordings were recorded for real! Something that was hidden when I use original DX200 was showed in great layering even the sound character will not render the sound layering more obvious like SP1000 do but you will be surprised by how it can be improved. Whispering sound in background of recording becoming more obvious to recognize without volume up. The echo of the vocal and instrument is more real.

I intended to do only Amp1 modification but when I hear DX200 with Fidelizer ultimate mod, I changed my mind. After I heard what the one that he by-passed the soft mute circuit, it sounded even better that I sent back my unit to do it too.

If you are good to go and have some effort to wait for it, I suggest you to send your unit for ultimate modification. But you can try only Amp module modification first to make sure that his stuff is real deal.

If you need a suggestion, try his paid firmware modification first. It’s cheaper way to hear the difference and you can always get the update when newer version fw is out.

For more information and the price, contact him directly. Hope this helps. 🙂

I’m also working on new optimizations in Fidelizer ROMs based on feedback from DX200 Ultimate Mod users too. 🙂

DX200 - Fidelizer Ultimate Mod

 

Here’s a new feedback today from iBasso DX200 customer in Indonesia. This is the first feedback from Fidelizer Ultimate Mod project.

Its gettin awesome as it burn in. I cant explain it technically, but this is the best dx200 mod ive heard. Because in indonesia there are few modder that can mod daps too.
Thanks to you!

I’m glad to hear DX200 Fidelizer Ultimate Mod is the best in Indonesia. It’s also the best in Thailand too. 🙂

Fidelizer Mod’s inspection for Cowon Plenue 1

 in News

I’ve been modifying audio gear for clients in Thailand for many years as a hobby. I figured I should share my research in Fidelizer website from now on so I’ll start the first one with Cowon Plenue 1. I’ll write my past projects in future when I have time.

I received Cowon Plenue 1 from my client for about a month now. He said it sounds quite bland and narrow requiring EQ to make it Plenue more juicy. Now it’s time for Plenue 1 to shine after modifying a few DX200 and X5iii with Fidelizer Ultimate Mod.

 

Fidelizer Mod - Cowon Plenue 1

 

Cowon Plenue 1 has quite interesting digital audio implementation. It uses Burrbrown PCM1792A DAC chipset with Wolfson WM8998 audio hub for interface. Before we continue with analog stage implementation, let’s see how PCM1792A works.

 

 

As you can see, PCM1792A has balanced output configuration requiring I/V stage for output stage. From our inspection, we found 3 x OPA1612 op amp doing the following jobs.

2 x OPA1612: I/V and LPF stage
1 x OPA1612: Output and buffer stage

The I/V stage will have two small pot for each channel to adjust voltage output. I thought about calibrating voltage output too as I did before with FX-Audio DAC-X6 DAC but the board was put behind display panel so I can’t do measurements during operation, let alone listening.

So I decided to use different opamps with similar specifications from different models instead. Output and buffer stage can be replaced with more powerful ones but I’ll pick ones that won’t draw too much current and retain similar sound signature.

I also thought about upgrading capacitors too but it needs to be very thin so I’ll look around for a while and see if I can find better capacitors to upgrade. I’ll upgrade battery wiring with high quality ones that should keep Cowon sound signature with other internal tweaks.

I thought using dedicated audio hub WM8998 with separated clock will have potentials for upgrading clock modules inside but it doesn’t look like I can find any information about its frequency like I did on Oppo UDP-205 recently (Will post about that later).

I think I can modify Cowon Plenue 1 DAP up to Signature level if I can find any worthwhile parts for additional improvements. For Reference level, I think upgrading opamps alone would be suffice for important parts. He should be happy without having to keep changing EQ now.
