In Reply to: Re: I have the TA9000ES, Samir-please respond.. posted by RT on March 26, 1999 at 08:57:42:
I think the key here is using the "ditital out" on the Toshiba DVD player. Let me tell you of my similar experience with my setup. I have the Sony 9000es preamp with B&K amps (3 and 2 channel 125 wpc models)and the NHT VT1.2 system with an Atlantic tech 262pbm sub. I wasn't all that pleased using my Panasonic a110 as the CD transport, which like you, I was using the digital coax from the a110. I also have a Pioneer LD player (504d) and had both digital rf out and ANALOG outs going to the prepro. I get a MUCH smoother sound using the LD players analog output. You may want to try the analog outs on your Toshiba.
I don't know if you have tried switching from the *normal* output of the Sony's preouts to the *low*, but this also seems to have helped my particular situation. I get a cleaner sound using the low output. I had one of the early units of this model (817 serial numbers last 3 digits)and have not tried the upgrade yet but I THINK one of the things the upgrade might do is actually lower the output on the *normal* setting. An initial buzz about this unit was a low output of the preouts but I think in reality (and confirmed by one of the magazine reviews), the unit was probably pumping out at 9v on the normal setting, which is probably why some have a hiss problem (i noticed the hiss at the -25 range with no source playing). It was cranking out too much. When I switched to the *low* output I removed the hiss compleatly. Of course now I am turning the volumn up to around -10 to -5 in most cases, which is about the 3 or 4 o'clock position, but I feel I get the smoother sound with this. The low setting is more than likely the 1v figure that folks were concerned about. I am hoping the upgrade does takes the *normal* setting and drops the voltage output from the 9v of the earlier units to around 3v or so. Hopefully they will leave the low output at 1v. If anyone can confirm this (ones that have done the upgrade), I would like to here from you.
I'll swith to low output tonight. I also plan on demoing a quality cd transport to see if this changes things. If so, I will become a believer that digital transports do sound different. I greatly appreciate your post.
RT.
Did the switch to low output improve your situation? Also, you may want to leave it that way for a few days even a week or so. When I first tried the low output I would switch back to the normal, which is obviously louder (cut the volumn back around -15 lower for the normal output BEFORE switching from the low output for comparison sake), trying to hear the differences (in detail, noise level etc, NOT loudness). I believe using the low output I have equal detail with less noise and it took a couple of weeks to get used to differences in the volumn slope. For most situations i now have the volumn from -15 to -5 (1pm to 3pm position) while in the normal output I had the volumn from -30 to -20 (12pm to 1pm).
I did switch to low output and didn't notice an immediate effect. I haven't had much time to listen to music lately, although I have watched a few movies with friends. Other than having to increase the volume, I didn't notice a big change in sound for home theater. I do hear some static coming from my rear speakers, but I can't tell if it is the recording or my amplifier. My speakers are to the rear corners of the room and about 5 feet back from the couch. Sometimes I have static from the rears and other times none. I only comment on this because I have heard that the Sony is generally dead quiet. However, I have my rears trimmed about 3 db higher than normal because I like the surround effects. When I lower it, it becomes less noticeable. I'll have more time this weekend to listen to music and will try to comment on the voltage change. My hunch is that its still the Toshiba player.
