Hi, Seeking for help.

I bought a used PHA 3. Connected to z7 through normal output and stock z7 cable, everything sounds great. But when I connect z7 with stock balanced cable, I can hear sound distortion if I move the cable from side to side. I thought that there is a problem with the cable and borrowed a kimber cable. But nothing changed, I can still hear distortion, especially If I try to bend the cable. This does not happen with normal (unbalanced) cable.

Does this mean I got a defected amp unit? Is there any way I can check this?

Sounds like a defected amp to me. Is it constant across all digital inputs?

 

[b1azer]

Yes, I tried laptop and walkman. I also noticed there is short crackling sound for a split second when I turn it on. During this time 'Hi-Fs' and 'DSD' indicators blink once.

there's a lot of pages to look through and was wondering if there's an adapter to use for 4.4 cables (MUC-M12SB1) and keep it balanced?
can i get links directly to the product (USA retailer preferred)

I haven't seen one, but I'm sure you could commission an adapter from someplace, or make on if you know how.

Sony is ending production of the PHA-1A, 2A, and 3. If you want one, you may want to get them while they're still around

I've got a PHA-3 for sale. PM if interested.

I'm being offered this amp for $300. In excellent condition. All accessories included.

Would the be a good price to accept.

Not related to the above post.

Doubt I would be willing to sell for that low.

Has anyone compared the sound of the PHA-3 to that of the top-end Sony DAP, the NW-WM1Z? Or its little brother, the NW-WM1A? Any insight would be much appreciated!

The PHA3 is superior sounding to the 1Z. I have both and the PHA3 is better overall in term of sound quality.

What about single ended though?

The 1Z Balanced is better sounding than PHA-3. You buy the PHA-3 because want to utilize its balanced output.

I am surprised....I have never heard a reproducible difference between balanced and single ended, on any system.
