It's basicaly the Symhony without the DAC section and without the sexy enclosure, it will better than Swing and Cantate, just uglier. I like the idea a lot, puting a lot of money in an expensive enclosure is nice, but sometimes price/performance ratio is more important
Various people have send me a mail for information on the new Concerto. Therefore a short synopsis.
Basically the CONCERTO is a SYMPHONY without the DAC section. However, some changes to the amplification section have been made.
- Instead of the LM6171 of the SYMPHONY the CONCERTO will use AD797 opamps.
- The CONCERTO uses a discrete volume control with a total of 64 positions (32 steps on the SYMPHONY). Typical step-size is around 0.7 dB. This gives a very smooth analog-like feeling.
- The CONCERTO has one pair of RCA-inputs and only one headphone output.
- The crossfeed filter has been slightly improved on.
The enclosure (two colors, black and silver) will be very similar to that of the STAGEDAC. Also prices will be comparible.
I hope that the amp will be available in February.
Currently the manufacturer is working on prototypes. Pictures and technical info will be put on my website as soon as these prototypes are available.
Hi Jan. Are you going to pay special attention to the PSU? I am thinking in getting a Lehman Black Cube Linear but, after buying your Stagedac, I think I could wait until February to check your new baby first.
after your excellent review with StageDAC, it seems that you still be with Jan, right? I ended up not to go to StageDAC but HD800+Symphony Combo. I have been liking the choice I did ever since.
However the StageDAC+Lehmann Black Cube Linear is so tempting. Let me know if you move that way, or right a review with that combo. It will be once again a hit.
> will there be a gain switch
Yes, there will.
> Are you going to pay special attention to the PSU?
Testing the AD797 showed that this opamp is extremely sensitive to the quality of the power supply, more then any other opamp I do have experience with. Therefore a lot of extra care has been taken. As an indication: This amp has a total of 85.000 uF filter capacity!!
> we want an option for a black faceplate with a silver knob.
Only on special request!
