SY, regarding the input connector you are complaining about. First, what model did your boss buy? What is the ID on the connector? This is important, because I specify NEUTRIK for the JC-1, JC-2, and JC-3.
However, cheaper products, even based on my schematics often use cheap look-alikes, and we have stirred up big trouble internally over it, in this past, when they tried to use the cheap, steel based connectors on the initial JC-1.
However, IF the model is the HCA-23, I will have to allow the cheaper connector to be used. If it is the HCA-21, I will contact Parasound and complain.
In any case, the 'sonic' aspects of this connector could not possibly be something that you would believe in or be concerned about.

It's the mechanical aspect (which could certainly have a sonic impact if the cable connection is loose)- they don't have a latch like good XLRs. His cables pull out too easily and he has to re-seat them every few hours.

PMA is this your personal unit, or a picture from earlier years?

I am lucky, my Halo JC2 has Neutrik XLRs. John, could you please recognize, what kind of RCA connectors are at this unit?

It is a picture from official Parasound website, as you may read from the web address.

Vladimir, yours are OK. But not gold plated, I would guess.

This exactly why, if you care about humanity, you should do a clear and concise tell all. True, it is basically all scattered here on these threads some how, some way, but getting it all togeather from here is almost impossible.

Even little me, at 51 years young, have started to document what I know that may be of value.

Ya' guys want a laugh? Here is my audiophile life is weirder than fiction story.

You are right, but RCAs seem to be gold plated.
To my regret, any separate preamp does not fit my demands, anymore. I was happy with JC2 only short time, after that I have come to an integrated amp + external power supply approach, and stay with it for 5 last years.

Are Neutrik less expensive than Canon XLRs ? I found Canon silver very good on the long run. When oxided, several successive plug/unplug and contacts are perfect again. I have some VERY old, working perfect.
The old problem with manufacturers or boss attempts to save few bucks, destroying the whole thing will remain for ever. I remember our boss, in 70's trying to change our epoxy boards to cardboards ones ! We had to argue with mechanical issues for the preamp, and temperature issue for our amp to keep them the way they had to be, and threaten him of our resignations !
