reveiw of OPPO 205 complete mod. client

OPPO BD player Mod. 2020. 1. 19. 10:25


I've owned numerous Oppo Blu-Ray players dating back to the BDP-83SE and I have always been pleased with their performance for price in my home theater. I thought they hit a home run with their BDP-105 and I considered it the best value entertainment hub I was aware of that included the convenience of a Blu Ray / SACD transport, multi-channel DAC, and a decent headphone amp. With an output impedance of 100 ohms at it's XLR outputs, I was even able to connect my 300-ohm impedance Sennheiser HD800S headphones directly to these XLR outputs and found that it sounded very transparent albeit a bit harsh. I always felt that the Oppo, more than any other device, had the potential of being the ultimate jack-of-all trades A/V device even if it was the master of none. If I was forced into exile to the planet of Xanadu and I could only take with me my HE-1000, a flat panel OLED monitor, my hard drive full of media and one other electronic component, that component would have to be an Oppo.

Oppo upped the ante with the release of the BDP-205 which included true 4K playback capability, Dolby Vision, and ESS's latest ES9038Pro DAC chips, With firmware upgrades, this device has now become a certified Roon Ready network player as well as an MQA-enabled DAC. Typical of most products in this price range, what held this unit back was it's power supply. Oppo saw fit to power the analog section of the BDP-205 with an independent linear-regulated PSU but chose to power the digital section with a switch mode PSU. For some reason, it remains a common belief that analog components benefit from good power supplies while digital components do not.

Back when I owned the BDP-105, while pleased with its feature set, I always felt it could be improved and I contemplated various upgrades from the likes of Modwright, Audiocom, The Upgrade Company, JVB Digital, and Oppmod. Of particular interest to me was the upgrade offerings from Oppomod as they were the only one offering an OCXO clock upgrade option in addition to PSU upgrades. Having exchanged several e-mails with Dr. Lee Jaehong, who personally performs all the mods for this company, I was impressed by what he was willing to offer for a relatively affordable price (at least compared to his competition) but because I could never find any credible reviews, I never took the plunge.

With the release of the BDP-205 last year, I really wanted the 4k playback it offered and so I went ahead and upgraded. I was impressed by how much better this unit was compared to my BDP-105 with regards to both audio and video and so I thought it would be worthwhile to explore my upgrade options once again. I explored the Modwright upgrade and spoke with Dan Wright who informed me that his upgrades focus solely on the analog output stage. In other words, he left the digital side untouched including its noisy switching PSU. Since I generally bypass the analog section of my Oppos in favor of one of my Chord DACs, this particular upgrade had no real appeal for me.


I decided to check out Oppomod again and the first thing I noticed was they were still in business (which I thought was a good sign) and that they had updated their upgrade offerings to include both the OCXO clock and PSU upgrade for the BDP-205. Furthermore, their "Complete mod" upgrade which includes the OCXO, their best LPSU, replacement of the fuse with a circuit breaker, and mods to the DAC board were being offered for only $850 which included return shipping from Korea. While Audiocom was now offering a much more comprehensive upgrade that included a Femto clock, a better PSU, and other tweaks that addressed vibration and RF/EMI, their upgrade was considerably more expensive and so I decided to go with Oppomod. Of course, such mods would void your warranty with Oppo so proceed at your own risk.

What I expected to take a few weeks surprisingly took only a few days and while my Oppo was in Jaehong's possession, he communicated with me frequently, even showing me pictures of the upgrade process. Returned with my newly modified unit was the unit's stock switching PSU. I opened up the unit and it was easy to see the modifications that were performed. As far as quality of workmanship, it appeared top notch. Cables management was very good and nothing rattled when I shook the unit. As soon as I plugged in the unit and turned it on, everything functioned as I remember. This is as seamless an upgrade as there is.



As far as what got better, well, I'm happy to say, quite a lot and more than I was expecting. Video quality improved in terms of better clarity and deeper black levels. Is it the same difference between DVD and Blu-Ray? No, but the improvement is easy to appreciate and was noticed by every member of my family. As far as improvements in audio, this was the surprise because the magnitude of improvement was considerably more than I was expecting. Based on the quality of parts used in the upgrade, I had modest expectations and was expecting this unit to perform on par with something like an Auralic Aries which, to be frank, was an optimistic expectation because I never thought the stock unit when used as a streamer feeding either of my Chord DACs sounded all that great -- passable for movies but not really for audio. With the better PSU, OCXO clock and other mods, there was a very noticeable drop in noise floor, better detail clarity, better detail layering, a greater sense of space, and more dynamic weight and this was evident at low volumes and high volumes with both 2-channel audio and multi-channel video. Is this thing now a world beater? It's not realistic to think that this machine can compete with Esoteric's finest purely as a CD transport and DAC but when you factor in its versatility as a streamer or transport to feed a better DAC, at its asking price of around $2k, this unit would free up funds to allow the purchase of a better DAC and combined with something like a Hugo2, I would now absolutely put it up against Esoteric's finest. How does this unit stack up against my highly regarded Zenith SE when paired with the tX-USBultra and REF10? You would think the Zenith / tX-USBultra / REF10 trifecta would trounce it and you would be incorrect. In blind testing, with this modified Oppo connected to either my Chord DAVE or Hugo2 via Toslink (which is arguably these DACs' best input), a difference can be heard with a slight preference for the trifecta but the difference is barely large enough to matter and certainly not worth more than 5x the asking price of the modified Oppo.

For those content with the qualities of the ESS 9038Pro DAC who are looking for a genuine world class, single-box, Roon Ready, MQA-enabled, multimedia entertainment hub, I'm not aware of a better performing unit for the dollar. Seriously recommended.

 OPPO 203, 205, panasonic UB9000, Pioneer LX800,

Opinion. The Pioneer LX800 is based on subjective survey on internal electronic circuits, chips used, and reviews from abroad, not a real one. Please note that it is purely subjective.

 

1. Video Quality Aspects

 panasonic UB9000 >> Pioneer LX800> OPPO 205 = OPPO 203

In terms of video quality, it's a big win for the Panasonic UB9000. It uses its own video processing chip.

The difference is even bigger when you play back Blu-ray discs, especially when you thought the picture quality was not good. He / she plays with a sense of stability elegantly. In addition, the quality difference between streaming services such as Netflix and YouTube is widening. 

In contrast, the Pioneer LX800, OPPO 205 and OPPO 203 use chips from Taiwan Media Tech. 

In the case of Oppo, many people think that expensive 205 is better than 203, but the video circuit is 100% identical. It is hard to feel the difference even if I see it. 

The modified Oppo will show better image quality than the Pioneer LX800.

2. Digital audio side

 panasonic UB9000> OPPO 205> OPPO 203

  The Pioneer LX800 can't be evaluated because I haven't heard it. 

 

 Panasonic UB 9000 sounds better than digital audio output via HDMI or SPDIF

is. The Oppo 205 has a variety of digital audio inputs, so it's great to be able to receive many different types of input.

 

3. Analog audio side

   OPPO 205> = Pioneer LX800> panasonc UB90i00 Japan Limited> panasonc UB90i00 (North America, Europe Edition)> = Oppo 203 

 

For analog audio output via the built-in DAC, the Oppo 205 and the Pioneer LX800 will be similar. Oppo 205 looks better on circuit and spec. It has a dedicated large linear power supply and uses one Saber 9038Pro, one of the best DAC chips available. The Pioneer LX800, on the other hand, uses two similar Saber 9026Pro chips to produce stereo output. On the other hand, the power supply does not seem to reach Oppo 205. 

 

panasonc UB90i00 Japan Limited uses the DAC chip of Asahikisei, Japan, to faithfully decorate it, but it is powered by switching power, so there is concern about noise inflow. If you convert to a linear power supply, there are quite a few improvements. 

 For the panasonc UB90i00 (North American, European edition) and the Oppo 203, analog audio output is a great expectation. 

 

4. Usability aspect 

 OPPO 205 = OPPO 203> panasonic UB9000> Pioneer LX800  

In this part, Oppo is the winner. Support for various playbacks such as playing videos embedded in the hard disk, and support for external subtitles in Korean is a feature that you can never expect from other devices. can.

 

 panasonic UB9000 has built-in streaming service such as Nexflix and YouTube, and the picture quality is very good. It does not play SACD.

  The Pioneer LX800 doesn't offer streaming service by default, and it doesn't even have an HDMI IN port, so it can't provide streaming service through the adapter.

High end UHD player에 대한 주관적 비교.

audio 와 Home theater 2019. 12. 25. 09:01

관심이 많은 OPPO 203, 205 , panasonic UB9000, Pioneer LX800를 중심으로 순전히 개인적인 관찰과

의견입니다. 단 파이오니아 LX800은 실제 사용해 보지는 않고 내부 전자 회로, 사용된 칩 그리고 해외의 리뷰 등을 바탕으로 한것입니다. 어디까지나 순수 주관적 견해임을 밝혀 둡니다.

 

1. 비디오 화질 측면

 panasonic UB9000 >>  Pioneer LX800 > OPPO  205 = OPPO 203

비디오 화질면에서는 파나소닉 UB9000의 압승입니다.  자체의 비디오  프로세싱 칩을 사용하였습니다.

특히 화질이 별로라고 생각했던 그렇고 그런 화질의 블루레이 디스크를 재생하면 그 차이는 더 크게 납니다. 안정감 있고 품위 있게 재생해 줍니다. 게다가 Netflix와 유튜브 등 스트리밍 서비스의 화질 차이는 더 벌어 집니다. 

이에 반해 Pioneer LX800와 OPPO  205, OPPO 203 은 대만 미디어테크사의 칩을 사용하고 있습니다. 

오포의 경우 고가인 205가 203 보다 화질이 더 낫지 않을까 생각 하시는 분이 많은데 비디오 회로는 100% 동일합니다. 실제 보아도 차이를 느끼기 힘듭니다. 

개조를 한 오포의 경우는 Pioneer LX800 보다 더 나은 화질을 보여 줄겁니다.

2. 디지털 오디오 측면

 panasonic UB9000 > OPPO  205> OPPO 203

  여기서 Pioneer LX800 는 실제 들어 보지 못해서 평가를 못하겠습니다. 

 

 파나소닉 UB 9000이 오포 보다 HDMI나 SPDIF를 통한 디지털 오디오 출력이 확실히 좋게 들립

니다. 오포 205는 다양한 디지털 오디오 입력 단자가 있어 여러가지 다양한 형태의 입력을 받을 수 있는 것이 가장 큰 장점입니다.

 

3. 아날로그 오디오 측면

   OPPO  205 > = Pioneer LX800 > panasonc UB90i00  Japan Limited > panasonc UB90i00 (북미, 유럽 판 ) > = 오포 203 

 

내장 DAC를 통한 아날로그 오디오 출력의 경우  오포 205와 Pioneer LX800 의 실력은 비슷할 것으로 보입니다.  회로나 스펙상으로는 오포 205가  더 좋아 보입니다. 전용의 큼직한 리니어 전원부를 가지고 있고 혀재 최고의 DAC 칩으로 꼽히는 Sabre  9038Pro를 한개 사용하고 있습니다. 반면에 Pioneer LX800는 이와 유사한 Sabre  9026Pro 칩을 2 개 사용하여 스테레오 출력을 만들어 냅니다. 반면 전원부가 오포 205에 미치지는 못하는 것 같습니다. 

 

panasonc UB90i00  Japan Limited 은 일본 아사히키세이사의 DAC 칩을 사용하여 나름 충실하게 꾸미는기는 했습니다만  스위칭 파워로 부터 전원을 얻고 있어 노이즈 유입이 염려 됩니다.  리니어 전원으로 개조 하면 이부분도 꽤 많은 향상이 있습니다. 

 panasonc UB90i00 (북미, 유럽 판 )과 오포 203 의 경우 아날로그 오디오 출력은 큰 기대 안하는 것이 좋습니다. 

 

4. 사용성 측면 

 OPPO  205 = OPPO 203 > panasonic UB9000 >  Pioneer LX800  

이 부분에서는 오포의 압승입니다. 하드 디스크에 내장된 동영상 재생 등 다양한 재생 지원, 한글 외부 자막 지원은 다른 기기에서는 절대 기대 할 수 없는 기능입니다 물론 스트리밍 서비스가 빠져 있지만 HDMI IN 단자가 있어 크롬 캐스트 등의 외부 기기를 접속하면 쉽게 극복 할 수 있습니다.

 

 panasonic UB9000 는 넥플릭스 ( 한글 자막 지원 ) , 유튜브 등 스트리밍 서비스가 기본으로 내장되어 있고 화질도 아주 우수합니다. 다만 SACD 재생을 하지 못합니다.

  Pioneer LX800 은 기본적으로 스트리밍 서비스 를 제고하지 않는데다 HDMI IN 단자 조차  없어 어댑터를 통해 스트리밍 서비스를 하지 못한다는 것이 가장 아쉬운 부분입니다. 

 

I2S 보드를 장착하고 완전 개조된 오포 203. 실용성면에서 가장 우수

New Zealand 북섬 캠핑카 여행 ( 통가리로 트레킹 )

해외 여행 및 트레킹 2019. 12. 24. 11:13

 뉴질랜드 북섬에서 가장 유명한 트레킹 코스는 통가리로 트레킹입니다. 하루에 하일라이트를 걷는 Alpine cross 트레킹도 있지만 종주를 해보는 매력을 느끼기 위해 Nothern Circuit trekking을 택했습니다. 45Km의 코스 이기 때문에 보통 2 박 3일, 길게는 3박 4일을 하지만 다들 충분한 체력이 되기에 좀 무리하여  1 박 2일 코스를 택하였습니다. 

언제 터질지 모르는 활화산 지대를 걷기 때문에 트레일 전체가 황량하기 그지 없습니다.

 

가장 힘든 정상 부분 입니다. 거의 토사 수준으로 발이 푹푹 빠지고 경사가 급해 최고 난코스입니다. 특히 강풍과 안개가 많이 끼는 곳으로  날씨 때문에 코스가 닫히기도 자주 하는 곳입니다. 

정상 부근에서 본 Red crater. 방금 용암을 뿜어낸 것 같은 느낌이 듭니다. 가장 최근은 2012년에도 분화를 했다고 합니다.

이 코스 중의 하일라이트. 에메랄드 호수 및 블루 호수 .  호수 옆에서는 진한 유황냄새와 함께 수증기가 올라옵니다.

다행히 날씨가 쾌청하여  환상적인 View를 얻을 수 있었습니다.

이날의 숙소인 Oturere Hut으로 가는 길은 마치 화성 표면을 걷는 것 처럼 황량합니다.

우리가 잔 Oturere hut. 하루 23명 정도가 잘 수 있는 조그만 곳입니다. 대부분 통가리로를 2일에 걸쳐 걷는 사람들이 묵습니다.

들머리이자 날머리인 Whakpapa 마을 까지 5시간 반 정도 걸리는 길을 걷습니다. 다행히 거의 평지 수준이지만 풍경의 변화가 없어 지루한 편입니다.

도착 한 시간 전 쯤에 만나는 Tarakaki 폭포 .  이  폭포를 경유해서 마을로 가는 길도 있습니다.
