Modwright vs EVS vs RAM vs ASI-Tek, OPPO BDP83


I recently bought a OPPO BDP83 BluRay player and the performance is very surprising for the $$. I'm interested in getting a MOD for the 2-channel audio. I understand ModWright, EVS, RAM and ASI-Tek offers mods ... can anyone offer recommendations? ... comparisons between them?

I have a ModWright Transporter and is satisfied with the performance ... I understand EVS also offers a Transporter MOD, has anyone compare it to the ModWright?

Thanks!

My Modwright modded Denon DVD players has sounded fantastic all these years and now it is being replaced by the Oppo. Still deciding who to go with. Modding these players is well worth it for the improvement in sound. It is like night and day. Beats having two boxes, one for video and one for audio when you can get excellent combined performance out of one unit.
Tennisamp, I totally believe that the Oppos sound as good as you say. Kyle's mods sound amazing. He's got a really good ear and seems to know how to extract the best potential from products. I've bought two of his modifications myself in the past. My reservations just stem from the cost ratio of the mods to the original product. I suppose if one is the buy and hold type of buyer, it's all good. But if you intend to resell, the resale value on a mod package isn't too great from what I've seen.
One more listening test on my friend's system.
Ayre C5xe; Bat-51se; Mono block Spectron Musican-3 mk2;
Von Schweikert VR-5se speakers.
Kyle of RAM brought over the same OPPO BDP-83 and a Marantz SA-11s1
which I believe had full mods.
It was obvious to me on the modded players, the bass was tighter/clearer with more air separating the musical instruments. The piano had sweet tones with more decay as well as the electric guitar. The vocals slightly warmer on the C5xe and about the same as the Marantz. I liked the vocals on the Oppo, with more air and separation, Diana Krall's voice was maybe sounding closer to natural.
At the end my friend was impressed, had many questions for
Kyle, who was more than willing to explain, why and what mods did what. Being my 3rd time listening/comparing, I enjoyed listening to these differences once again.
I got my unit back from Rick Schultz at EVS this week. I had the full multichannel mod done. For a couple of evenings I played a bunch of SACD’s/DVD-Audios and a couple of movies. Sounded great through my system (Lexicon MC12 analog, ATI amps, Martin Logan Speakers) but it is always hard to remember what it sounded like a few weeks ago when I sent it in. The big test was to go to a good friends who works in the business and has an unmodded unit so that we could A/B. Both him and my wife were extremely skeptical. His system is MC12, Lexicon Amps, Revel Speakers. Since I was in a money back period, this was the test to whether the unit went back and have it replaced by a stock version.

The 3 of us started by listening to Diana Krall, Money from Dark Side of the Moon and Derek and the Dominos on SACD’s on the stock unit. Just before switching cables, which took only 2 minutes, we replayed money. The plan was then to listen in the reverse order on my modded unit. It took all of a few seconds for each of us to look at each other and easily conclude the modded sounded significantly better in essentially the ways Ric had described it would. Airy sound with each instrument (or cash register) sounding incredibly clear and distinct with a great soundstage. At that point, the sale was final and skeptics won over. Diana Krall’s voice was stunning, every breath noticible. Derek and Dominos had a little less effect but it was still there. We didn’t test CD’s but I would be surprised if they also don’t shine.

We then tested video. My friend and I both have a Samsung SPA800P, the most accurate product available (except for the 900 model which can do better blacks) My friend is one of the best calibrators anywhere – Joe Kane uses him at times – and finds artifacts in milliseconds. We played some test patterns and a scene for The Rock without sound. The test patterns should no difference and a few seconds of the scene where they break into the rock was replayed dozens of times looking for a small difference. In the end nothing conclusive, both the modded and stock units looked essentially the same. We didn’t test a DVD.

If you want better analog sound from the OPPO, the mod will certainly give it to you. After last night’s test, I have no doubt and neither did my very skeptical wife or friend. The conclusion was immediate. For video, nothing much changed and the older MC12 does not have an HDMI input to test digital audio.
