Here's my 20 cents worth regarding PW DAC, preamp and digital volume control. It's a long diatribe. For starters, I tried running straight to Pass Labs X350.5. Extremely clean accurate and 2 dimensional sound but lacking musical involvement. I wanted it to be better DAC to amp because it would save me 2 chassis worth of electronics, tubes, cable and power cords. You know, the usual "simple is better" approach. But not in my system. The Cary preamp acts as the General in my system. He runs the show.
Yes I use more than the DAC 50% volume threshold to drive my MBL's.
Yesterdays note:
Last night listening to some Chris Rea, then REM, I felt like I hit the audio lottery. This morning when I looked at our living room, I stood in awe of our stereo. I even took a picture. Before we went to sleep last night we spoke of this journey some will understand that gets you to a point where listening to music becomes more of an emotional experience that a study in audio. You know, I need to fix that or change this or what if I did the other. That really hasnt changed as this is our hobby and tweaking audio is part of our lives. It was tweaking that got us here. Ive been an audio nut for 44 years. Im 54. It was that first Sony reel to reel with the Bi-directional head that got me hooked. What a beautiful machine.
Ive been building cables almost all of my life. My job is about cables. The night before I built a set of XLRs to replace my other DIY XLRs. My third set of XLRs, from Pass 350.5 to Cary SLP-05(the General) is the Harmony Tech Magic IIs. I needed a reference set to judge my own home built brews. The Magic IIs bettered my former DIYers so I found some 7 nines mono crystal silver from Taiwan and lovingly built this set entirely from cotton. No shield, no dielectric, just some Vampire connectors and cotton period. No my jaw didnt drop when I plugged them in. They were better than I thought not being run in and I hope they get better with time.
Our DAC, the PS Audio Perfectwave DAC is an amazing piece of hardware. Ive had some good ones but this thing just gets it. Folks talk about native mode being the mode of choice. In our system that simply hasnt been the case. I love up-sampling to 92 on redbook CDs. Its simply sounds more refined. Not on all music but most it seems so far. Filters are great to work with as well. One small problem we have which I plan to fix is with both filters and up-sampling on this DAC. You cannot see what filter or up-sampling frequency is selected from your chair even with glasses. PIA. I plan on programming that feature that into my MX3000 remote. The way we use volume is a combination of DAC volume (above 50%) and Cary volume. The General likes to be involved with his gain. But I need more time to test that theory in our current configuration.
Our system has been sounding good, very good. Ive been trying to fall in love with the MBL 121s. They are a very different speaker and going from LS6 line arrays, then to Dynaudio Confidence C1s which are broken and finally to the MBLs (my wifes dream speaker) is a serious ear\brain adjustment. Dialing in the JL Audio Fathom F113 in the system hasnt been easy either but with a long conversation with JL Audio tech support (the best by the way) I no longer have a sub in the room. Oh its physically there and low end sounds are present, it just that you dont know its there.
So listening to some Chris Rea last night we talked about how good it sounded. It did sound well, maybe as Good as I've ever heard but I didnt warm up to the top end frequencies. I thought they sounded a bit dry. They were clean and clear with a good shimmer. It was just that they really didnt capture the actual body of the instruments as I know them. I spoke of this after the song ended and sat there thinking well, that silver cable has got to break in, give it time. Then I got up, went to the closet, and drug out my box of tubes. I grabbed a pair of red based RCAs and replace 2 Electro Harmonix 6922s with the RCA flavord pair and sat for a listen. The EH's are typically detailed and taut in the bass, the RCA's Red bases typically add warmth in our system.
Wait. WTF? The 3 of use looked at each other in synch and if to say together WTF. We sat and listened occasionally sharing glances at one another. One song led to another. They were all playing in a harmony and melody I never heard before. My wife spoke Im getting goose (shes Russian and forgot the bumps part). after running through the entire album I stabbed the SB3 control to the next album REM Automatic for the People I think. First song Drive. WTF? Every instrument was so in its own space, so accurately and melodically presented it was stunning. My eyes frickin teared up! Song after song played in just an amazingly real portrayal of a musical event. We played B-Tribe Sensual Sensual, a CD weve played a million times. We never played this CD. The songs floated in levels layer upon layer within itself and authoritative (think I made that up) itself on yet another queue was the ability to render each instrument or vocal in it's own event. But this was not as much a dissection of music in as much as it was being able to watch the different performances from within the music. My brain in the mean time we could not get over the fact that changing 2 tubes in a group of 6 (maybe the 2 most important ones in the preamp) could have such a profound effect. I never even liked the RCA red based tubes in my preamp! I dont even know why I chose those at the time! Moving on I switched to something old school in my playlist. The Beatles Yesterday. Again, the portrayal of this song was so completely natural and again, melodic, real, it was stunning.
Cant wait to get home. No interest in dinner. Bring on the music!
Sorry for the long post. I'm just really excited about our room tunes right now.
