Hi all,

Recently acquired a BDP-105D on Craigslist and hooked it up this weekend.

Previous system chain: PS3/Mac Mini --> glass optical / USB --> Peachtree Audio Nova125 (integrated DAC/amp) --> Clear Day Cables Double Shotgun solid core silver cables --> Magnepan 1.6QR

New system chain: Oppo BDP-105D --> Clear Day Cables solid core silver unshielded, unbalanced interconnects --> Peachtree Audio Nova125 --> double shotguns --> Maggies

(Bolded components are the only things I changed.) Speakers set to large and proper stereo settings enabled in the Oppo. Fixed signal output and use Peachtree preamp functionality. Power conditioner is APC H15. Everything plugged into appropriate filtered ports. Power cables for Oppo and Peachtree are Shunyata Venom3.

The first thing I noticed when upgrading the chain was a much harsher and strident sound using some material I was pretty familiar with. After letting the system settle for a day or two, I tried again yesterday and the same negative attributes were still present. Curious, I hooked up my same optical cable from the Oppo to the Peachtree (bypassing the Oppo DAC and the interconnects) and the sound I was used to returned, a little less detailed and with slightly less resolution, but not cringe-worthy.

Since the Oppo uses the ESS Sabre 9018 chip and the Nova125 uses the ESS Sabre 9023 chip, I doubt the DAC switch is the culprit and think it's probably the silver interconnects. They are a 1m pair, unshielded, using the same solid core silver as my speaker cables that I preferred when A/Bing two years ago to the copper speaker cables I demoed against (AntiCables level 3 reference).

Has anyone here had a similar experience? Any recommendations for a good copper RCA interconnect to try out and determine whether the silver interconnect is the culprit? Sort of disappointed after reading about the player for so many years to not be able to listen to it comfortably for more than a few minutes after first hookup...


unshielded, unbalanced interconnects = garbage

I believe your source of "harshness" is the input sensitivity of your Peachtree preamp coupled with Oppo's unbalanced output voltage at fixed(max) volume. Your Peachtree's specs say that it has an input sensitivity of 1.2 volts. The Oppo's rca outputs at fixed(max) output are 2.1 volts rms. You are way overdriving your preamp. You need to put your Oppo into variable volume, and lower it down about 6 db, which would cut its voltage output in half. Since each step of volume on the Oppo is 1/2 db, you'll need to lower volume to around 88 (which would produce an Oppo unbalanced output voltage of around 1.05 volt rms. The harsh sound should go away after doing this.
Having read the various replies I would agree with this.

It would be also interesting to know what your reference recordings are because I'm betting your system has just went up a notch and you are now hearing compression a lot clearer. When my system got far too potent before I switched amps-the variable volume output was the only thing that allowed me to listen to some recordings.

The notion that the "lower" models are better designed for stereo playback seems pretty strange for me-the majority view from what I've seen is that by moving up the Oppo chain to the 105 usually results in improved stereo.

I would buy a better interconnect anyway but be aware sometimes when you buy a new component is the start of having to totally reassemble your system to get the best out of it. Sorry...:-)

Aah... Just the kind of review that I was looking for the Oppo BDP-105. I listen to a lot of rock - Eric Johnson, Steve Vai, Joe Satriani, Rainbow, Dream Theater, Rush, Kings X etc. to classic Rock like Steppenwolf, Cream, Blue Cheer, Iron Butterfly, Led Zep etc. & audio impressions listening to them on the 105 are few & far in between.
My setup is a 105D (XLR balanced connections) to a Yamaha A-S2000 driving a pair of Wharfedale Denton's (80th Anniversary Edition).
Though the speakers would prefer Jazz or Classical, I must say thanks to the Oppo, my Rock library shines with some truly stellar audio immersion especially when I'm listening to Steve Vai's Fire Garden album. The album has emphasis on bass across most of the tracks but the Oppo delivers a tight punch with sweet highs (No searingly bright treble thanks in part to the Yamaha's as well) on "Warm Regards." If you can get your hands on the remastered HD version of Rush's Presto, the track "Hand Over Fist" is truly staggering to hear on this setup. The Oppo really opens up the dynamics of the song, which on other players like the Cambridge or Marantz Universal Players sounds horrendously whinny for my taste.
On the flip side I gave a go at Steve Perry's Streetlife album's "If Only For The Moment Girl", OMG, the sound was truly astounding. I mean the track itself had great mastering. From Vinyl to Digital, this track has always been astounding for me. & Then I heard it on the Oppo..... WOW!!!
Let me not even get into Jazz. Pop in a CD of Billie Holiday & be ready to cry tears of bliss.
OPPO BDP-105D is PHENOMENAL!!!

Setup:
Oppo BDP-105D
Yamaha A-S2000
Wharfedale Denton (80th Anniversary Speakers)

P.S. - I have heard people talk about Oppo's preamp capabilities. Actually that is not the case. The BDP-105/D has NO preamp capabilities, except as a separate for direct analog outs for multichannel audio decoding formats. Yes you can connect it directly to a multi channel power amp using Oppo's digital volume. But please note that digital volume essentially strips the bits from the audio stream to lower the volume which means lowering the volume also means lowering the clarity of the audio stream.

Hi,


Enjoyed reading your post till I got to the last bit!!.

IME you are incorrect blaming the OPPO's digital volume control for any negative effect on SQ.

I, and many others, PREFER using our OPPO's hooked DIRECT to amps or active speakers.......especially for Stereo.

The resultant SQ is extremely good.........in my case clearly BETTER than using my $4K Pre!!

Any volume control issues resulting in poor SQ would more than likely relate specifically to the input sensitivity of the partnering equipment.........

NOT the OPPO.

Please see here........

And here......

http://www.oppodigital.co.uk/UserFil...ction%20V2.pdf

This has been previously discussed many times.
Search earlier in this very thread.

BTW.......I would recommend only paying attention to posts by actual owners who know from actual experience what they are talking about.

Cheers

^ The Analog audio outputs of the 105 and 105D do not do Volume control in the digital domain. Volume control is done in the Analog domain (i.e., as part and parcel of the operation of the DACs) with digital level selection. There is no "bit stripping" going on.

When I found my system was too potent the variable volume was a nice added feature on the Oppo-it gives you a much tighter volume control.
