Parasound A21


Hi Guys,

This is my first post so please accept my appologise for being not technical/ wrong!

I've a set up consisting of

CD Player Primare CD31
Speakers Paradigm S4
Parasound speaker stands
Subwoofer 2 x Rel T3
Preamp Parasound P3
Power amp Parasound A21
Belkin power purifier
Nordost Red Dawn interconnects XLR and RCA
Nordost Red Dawn biwire speaker cables

I'm pretty happy with my system but i still feel somehow it isn't completed! Hence, I've 2 questions which i'd like your advices/ comments on?

1. To me, the use of XLR on my system doesn't produce as good sound as RCA (interconnect between CD player and Preamp) due to RCA allows me to adjust the Treble and Bass on the Parasound P3. Will this story be completely opposite with say the Parasound JC2 preamp?

2. I'm tempting to obtain a used Parasound A21 to trial biamp or bridge mono setup. I do understand this is not a real biamp as i still have the passive cross overs in my speakers! (my gears are still under warranty). Hence, can you guys please give me some advices on whether i should biamp/ bridge mono? I love to have more of that airness sound come out of the speakers (not sure if i've explained correctly here!)

Thanking you all in advance for your advices
Tim

IMOP powercords will effect the sound far beyond sublte improvement just 6 months ago I went from all AC-3's a monster HTS 2500 and a 10awg and 12awg dedicated 20amp lines, to a Ps audio Quintet fed from a Ps audio Power Port Premier by a Statement Sc for my sources and 3 channel amp and sub all on the 12awg line and the A21 fed from a Soloist Premier via the AC-10 on the 10awg line some may feel putting the amp on a conditioner is a no no as i believed as well, before this up grade the A21 was plugged directly in the wall. that was until I read on another forum where a guy ran his JC1 mono blocks from the Soloist and reported precieved increase in volume. Couriosity got the best of me and ordered one with the rest of the ports and conditioners and low and behold peace of mind and great dynamics and black backgrounds. Point I'm trying to make here is this was the best upgrade I could have ever made and from this point on I will biuld from power on up. I got to keep my gear and it was all under $700.00.
Primare_cd31,
Did you try the A21 without the Belkin? If the direct to wall sounded better, then you might need a non-MOV filter - like the Brickwall PW8R15AUD I have.
I have had o success with biamping. Now is a good time to audition various amps in your present set up. Most dealers will allow this.
I have had very good success in Bi-amping and mono blocks but it is also a good idea to try varius amps if you can. When you take some load off a single amp while bi-amping, alot of times you will create more head room. Some like to run one brand to the highs and mids and another to the woofers. I have not tried this myself but it sounded interesting anyways. I am also a firm believer that power cords and power in general are extremely important components as well. Take the power cord as serious as the IC's or speaker cables.
Thanks guys.
However, what will happen to the impedence mismatch when running difference brand power amp.
I've added on a Bryston LP2 (run in daisy chain) to feed signal into the 2 x Rel T3
I'm considering to replace the Parasound P3 with Moon P5 or JC2 preamp eventhough i'm a bit reluctant with the Moon due to the impendance issues. A bit confuse here!
