I received mine today and first thing was to check the tubes. On my trusty B&K 707 the Chinese tubes tested excellent, at the top of the power range and both sections of each tube were exactly matched. I'm impressed at the constantly improving tube quality coming out of China and Russia.
Installed them and set up the DV as a pre-amp in one of my computer rigs running WAV and Hi-Res files through FooBar 2000 via usb to an FX-DAC6 that arrived today also. Output of the DV goes to my Conrad-Johnson Sonographe SA-120 and out to the speakers, Infinity Crescendo Series CS-3008s.
In a word, Superb. Brand new Chinese tubes not even settled in and the sound is magnificent. Dead quiet, No buzz, hum, burning smell or anything that some others have reported. I will use the tubes for a week or two and then start rolling some of my tube stash from the 50s and 60s.
All in all, extremely satisfied with this purchase. I am amazed at the bang for buck that the Chinese Hifi industry is making available.
If you want to experience the joys of tube pre-amplification and you have other quality gear, you will not be disappointed with this machine. It rivals famous brand pre-amps I have owned costing ten times the price.
Digging the ol Infinity speakers! I owned the RS 6000 back in the day. These look like Cresendo's?
Whats the story of FX DAC? Are you using it with DV? Do you like the DarkVoice tube sound quality? Does the DAC help w your source material?
Hi Keefer, Yes indeed! Infinitys forever. I have owned many different speakers up to the $5K KEF 107s and these Crescendos are my all-time favorite. They are the sleeper in the used market. Nothing touches the upper mids-highs of those EMIT tweeters. I have the whole series, 3006-9 (-; and run a stacked set of 3009s in my living room in a D'Appolito setup.
The FX DAC is brand new, wanted to try out the Cirrus Logic chips vs the BB1794s in my Xiang-Sheng DA-03A. It is a wonderful little dac, dirt cheap and sounds great coupled to the DV. Yes, as I mentioned in my previous post I love the sound of the DV and that's with Chinese tubes, and not even broken in yet. I have a boxful of 6SN7s and 6080s to play around with after I run it in for a hundred hours or so.
I'm spoiled and only listen to optical/coax/usb inputs into a good DAC and then out to the tube pre-amps..(-;
Except vinyl of course, that goes from my Conrad-Johnson EV-1 to the tube pre-amp.
Those RS-6000 were mighty fine speakers! You'd have to go a Long Way to beat those....Enjoy!
Very cool Gugliermo! Stacked 3009's...that's wild, man. I almost bought a pair of 3006's recently but he wanted way to much. If you ever want to sell something from the set, let me know. So a thumbs up on the DV n FX dac. Nice. I might jump in on the drop for 336. I just bought the new Beyerdynamic DT1900 PRO w Beyerdynamic A20 amp. Killer,killer combo. These cans have the meatiest bottom end, great mids and detailed highs. Want to add some tubeness to the rig and thinking strongly about the DV. or Woo Audio amp. Thanks- stay in touch
I don't listen much to headphones but I live in a near field sound setup. The stacked Infinitys are a combination of linear array and D'appolito. Been using that setup since stacked large Advents in the '60's. (-; This rig eliminates the room. First and second reflections have no chance so it's like being inside a large set of headphones.
The 3006's cost $960 in 1992, that's about $1600 in today's money so they were some pricey but very excellent bookshelves. The 3009's were around $3K and the whole Crescendo line was an economic disaster for Circuit City. They are basically the famous Kappa line in less expensive cabinets but it seems people did not go to Circuit City in the '90's to buy a set of $3k speakers..
I think the DV will add very nice tubeness to your setup. Hard to go wrong with the 6SN7 family and the DV is quality built.
I tried some new tubes and indeed, the sound bumped up considerably, smoother, more open and a little less punch than the Chinese tubes. Using a 1963 RCA 6080 and a 1948 Raytheon 6SN7. Also switched to my Xiang-Sheng DAC which is a better DAC than the FX-X6 and has a 5670 tube in the circuit, Golden sound.
The Beyer setup sounds like a pretty topshelf headphone rig. Cheers.
