In Reply to: RE: Finally! Been waiting for somebody to mention Level 7 Level 7 SACD Player (Modded) posted by Joe Rasmussen on January 15, 2009 at 05:53:44
I have a VSE Mod 4 Sony 9000ES that I use for two channel SACD/CD and an Oppo 980H that I use for MCH SACD over HDMI in my hybrid stereo-surround sound system. I understand from looking at Joe Rasmussen's site that the Oppo can be modded with the Terra Firma mod. Would I be better off modding the Sony or Oppo at this point? If I mod the Oppo I could us it for both Stereo and surround duties. Not sure if that is feasible or if there would be a performance difference between the Sony and Oppo with the terra firma mod. Thanks for your insights

Roy,
If you compare your Upgraded SONY with the stock OPPO, I'm sure you prefer the sound of the SONY.
We can add a Terra Firma clock to both units, and both will gain similar performance, but because the SONY is starting from a higher place, it will still sound better.
Your SONY has quite a few possibilities to be even further improved, as well as the Terra Firma clock. Take a look at the linked review for Karl's take on the possible improvements.

> the SONY is starting from a higher place, it will still sound better.
I can confirm that. I have a Sony SCD-555ES (not sold in the US) Level 7+ (Terra Firma Lite) and an Oppo DV-980H (also with Terra Firma Lite upgrade) side by side right here. The Oppo's output stage by-passes the post DAC audio, has the same type of digital noise treatment as the classic Sony players. The Terra Firma Oppo is a steal and the TF benefits are VERY obvious. Is it better than the 555ES? No, it is certainly not! But what a bargain!!!
I sold a TF Oppo to a certain importer of a SACD/CD player from the UK. This player sells for four thousand pounds and makes claims to redefine high end digital playback etc. He has asked me not to name it, but the TF Oppo is not just a bit better, the difference is in another league.
BTW, for those into NOS-DACS, the Terra Firma makes a superb transport. But the Oppo must be the master and the NOS-DAC the slave (no clock). But this is only RBCD. Mind you, it's very easy to fool visitors they are listening to hirez. ;-)

I dont understand this.

Joe is allowing his terminolgy to get a little confusing, I agree.
He makes a DAC he calls the NOS-DAC, NOS in this case meanining Non-Over-Sampling.
He also Upgrades OPPO players with a TerraFirma Lite clcok, which he seems to be calling a "TerraFirma" in itself.
I understand why you didn't understand.

Allen,
Thanks so much for that quick response. One follow-up question. Base on an prior post about the content of VSE Mod level 5:
Basically Level 5 comprises:
1/ the same Level 4 analog Upgrade module as has been available for over a year now - but with the Clock section removed.
2/ the same now well proven 'Very Low Noise' (VLN) clock 5 volt regulator that was the addition to Level 4 to make Level 4.5
3/ a completely new and seperate module that contains the TENT clock, the VLN regulator and the 'piece de resistance' : it's own AC transformer/diodes/capacitor assembly to independantly power the VLN regulator (& hence the clock) without taking any DC power from the analog module or the player itself.
Does the terra firma mod replace what is done in going from Mod 4 to 5? I guess what I am really asking is if I really want to go all the way with modding the Sony...do I skip over Mod 5 and just do Mod 6 and Terra Firma? Thanks
Roy
Roy,
> if I really want to go all the way with modding the Sony...do I skip over Mod 5 and just do Mod 6 and Terra Firma? <
Level 5 included a lot more than just the RCM clock, such as replacing all the signal (analog and difgital) wiring with silver wire, and a lot of small changes to couplig caps etc.
Did you install your own Upgrade from a kit or did you have one of our agents do it. If an agent, give them a call and work out the best path for your machine.
If DIY, private email me.
