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!

The Oppo BDP-83, while listening to the same cd of course; initially I had to turn the volume down, it had more power out than my C5xe. Some of the mids sounded equal to the C5xe but overall the bass was (to me) more defined as well as the highs.
The music seemed more separated from the speakers also.
He showed me the modded the power input, a Super Clock4, and
Audio Consulting output transformers, which were balanced outputs in this set-up.
I was surprised and a little disappointed that it (overall) out performed my reference Ayre C5xe.
I will mod my Oppo BDP-83 but with the Ultra clock instead. I was informed that the video quality will also be improved.
I'm like Photon46, it's counter intuitive to mod such a platform. If I didn't here it for myself I would be in doubt too. I have to trust my ears on this one.
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.
