Basic Questions

I’m a long-time middle tier/value home theater consumer.   Recently I’ve moved toward trying to get more out of my 2 channel listening (vinyl, streaming, Hi-rez, etc).  I moved from my DefTech towers to Paradigm Persona 3F. Big 2 channel improvement, but not the level I heard while auditioning them (with a separate amp).    

My media room is 18’ wide x 24’ deep.   I listen at moderate volumes, only occasionally cranking it up.  Unfortunately, live about 4 hours from closest hi-end sound shop, so not easy to audition equipment.

Some basic questions:

1. Do I need a pre-amp and why?  I’m fairly happy with my AVR’s sound programs.

2. Will additional amp work solely with 2 front mains, or power to entire HT system?

3. Is it simple interconnect from AVR to Amp, then speaker cable to front speakers?

3. I have seen  strong recommendations for Anthem STR and Parasound A21.   Any affirmations or other recommendations (looking to keep things under $10K with interconnects.)

My Equipment:

7 speaker Home theater

- Paradigm Persona 3F mains (“suitable amp power range = 15-400 watts; “max input power 200 watts). Morrow Audio SP6 speaker cables

- Definitive Tech UIW RSS II sides (10-200 watts per channel)

- Definitive Tech UIW RLS III rears (10-325 watts per channel)

- Definitive Tech CS-9080 center (300w internal amp; “recommended input power” = 50-300 watts per channel). Morrow Audio Sp4 reference speaker cable. 

Yamaha RX-A3080 9.2 Channel AV Receiver

- Rated  output power 2-channel driven 20Hz-20kHz = 150 watts
