Audio Aero Pirma DAC versus MF TriVista 21 DAC

I would try an aftermarket powercord. I use the Elrod on my AA Capitole. Not sure about the Prima. Power cords tend to be used these days as tuning devises. I know my Audio Aero w. out the Elrod can be less than musical & slightly harsh. With the Elrod everything snaps into place. On another note,you will need time to let everything settle down to hear the benefits. Although you will hear a change right away,the long term listenability will be the ultimate decision maker.

One last guess, is the Primas tubes might be noisy. It can happen.

Elrods come up used quite often here.

Renaat,

You can also search the archives here if you want to try and make something yourself. The Michael Green kits are around $250, and you will be amazed at what just a little room treatment can do to take the harshness out of the sound.

Best of luck,
Howard

Mattheus,

It's indeed most likely an AC problem, but probably otherwise then is stated before. I've had the same thing occuring with my auditioning of an AA Capitole mkII. In my case I had the AAC correctly plugged in my MIT Z-center (wich is very important with AAC), but my poweramp in the wrong way. Indeed pain in my poor ears! First I also tried other cables, but this didn't chanched anything of course. Everything plain on the mains, that was the moment I discovered my mistake with the poweramp.
So check if the rest is connected in phase on the main.

Good luck, Edzard

Hello,
I just compared the trivista21 with a.a. prima dac (latest version)...
both are very good. both are very smooth & neither has
the nasty digital sound that many cd players have. neither are sharp. the aa is costlier and maybe worth the difference in price. the aa has more depth and is a bit more involving. unfortuantely, cable makes a difference
the $1200 aes/bu cable was significantly better than the $30 & $75 coax cable. however, sound on the cheaper cables
was enjoyable and had no unpleasantness. i used an accustic art tranport (excellent i think)...it is possible that you may have to
play around with transports/dac combinations (along with cable) to get rid of the nastiness you are experincing

I own the AA Prima SE DAC and have got to compare it to the MF DAC on two occasions using a Sony SCD-1, Audio Research CD3 MKII, and an Orpheus Zero D, as transports. The digital cable was always the Siltech G5 golden Ridge. No matter what the system used the AA was always a much nicer sounding DAC. More musical and at the same time much more detailed with a cleaner sound to it. Bass control was better and everything seemed more focused. When using the Orpheus as transport with the Siltech the AA Prima SE DAC, to my ears it does everything right.
The rest of the system was Audio Research and Maggie 3.6 speakers.
