DENAFRIPS DAC ---- Owner Impressions, Feedback, General Discussion, Questions and more....

Hi George, @georgehifi

Thanks for your kind words on my system and review. And thank you for the excellent Lightspeed Attenuator.

My understanding is that the Acoustical Systems battery amps never went into production and there were only a handful of pairs made. I guess the company wants to concentrate on analog front-end components and phono preamps. I was told that their input impedance is 100k ohms and that there is only one MOSFET per mono amp. Your Lightspeed Attenuator is sounding very nice feeding these amps. I very much appreciate that the Lightspeed is outstanding value for money, and so I understand the reason for the wall wart PS that is supplied. My My next point is in no way intended to be a criticism given the outstanding value proposition that the Lightspeed is, but rather the opposite as to what an excellent design the Lightspeed is. I would like to note that it scaled up beautifully with the custom silver wired power supply unit I managed to get for it.

All the best!

Thanks for your kind words on the Lightspeed, I noticed you have the dual mono version, good choice as you can perfectly centre the sound stage image regardless of speaker position or room abnormalities.
Battery is even better again for the Lightspeed, I recommend this Lithium-Ion rechargeable one, you can get up to 2 weeks listening in between a recharge, it has the blackest back ground (as if your system has switched off in between notes/tracks)

Long time ago an amp that used Nelson Pass Class-A circuit used battery, which was highly regarded call the NEW-Class-A CD33 or something.

Cheers George

Forgive me if I’m wrong, but did you used to own or still own a Lampizator Atlantic? If so, can you describe the differences between it and the Terminator? 

If something goes wrong mine did shipping is very expensive. I had the ares

@viablex1   I'm copying your post from a thread you initiated:

I ordered an ares and received shipment about a week to ten days ago. Initially it would not turn on. Then I saw lights and eventually sound. Not sure what was going on but it was a prelude to what happened next. I liked the sound very musical but when using the first coax input I kept getting this weird volume problem. when a track would start it would cut almost completely off then go back to the original volume. So I needed to send it back which I am doing but it is expensive because there is no USA support at all. I almost bought the Pontus but glad I didn't since it would have cost even more to ship it back.

I am not saying never buy one or bashing denafrips just know if something goes wrong shipping back is exorbitant
