Does Bi-amping really make a difference in sound?

I have really been torn in the past week in how I should improve my Home theater stereo System. I presently own the following gear:

Oppo Blu-ray Player
Yaqin Tube Buffer (w/ 6SN7 Tung Sol Oval plate Tubes)
Cambridge Audio DAC Magic
NAD C-375 Integrated Amplifier
PSB Synchrony Two loudspeakers
Nordost Red Dawn Ics
Audioquest VDM-X Digital Cable

An experienced audiophile and design engineer who designs speakers and custom electronic gear has told me that in order to improve my sound drastically I need to Bi-amp my speakers. Since PSB speakers have separate crossovers for the tweeter/mid and bass, that I could take advantage of this and bi-amp them and really make them sing.

I was told that I should buy a another amplifier and use the Pre outs of the NAD C-375 Integrated amp and even tailor my sound by selecting the appropriate amp with the same power wattage.
I am thinking of getting an NAD C-275 or the Vincent Audio SP-331 Power Amp to connect to the Pre outs of my NAD C-375 and bi-amp my speakers with two sets of Harmonic Technology Melody cables running shotgun to my speakers.

I also plan to upgrade my digital cable to the HT Digital Silver cable and maybe the HT Silway link Silver to my DAC to NAD C-375 connection over my present Nordost Red Dawn.

My dealer friend disagrees with my approach that bi-amping will improve my sound as he said he conducted a similar setup with the PSB Synchrony Ones in his store and did not hear any differences. I am wondering if he is just wants to steer me in the direction of getting a Rogue Audio Preamp and NAD C-275 combination, which I have considered as well.

Any expertise and advice in this situation would be greatly appreciated. I unfortunately cannot tryout these situations or go listen to them in a store due to my location and have to rely on people’s advice.

Thanks Minori for that insightful and common sense approach to bi-amping. I totally agree with you. Investing such money should involve a person being able to listen for themselves in their particular listening room since many factors are involved.

That is part of my problem, Currently living in Las Vegas (which does not have many High End Dealers), I am not in the position to be able to borrow equipment and try stuff out. I too, had a excellent relationship with a dealer in San Diego (Stereo Unlimited), and I did not even need a credit card to borrow equipment. FYI, I been to Stereo Design when I lived in San Diego. Nice store as well. I still connect my Dealer friend in San Diego, who has been in the business for over 35 years who actually did a step up for me to see if he could hear a difference, and he said he did not. Still I understand to do bi-amping correctly involves a pain staking approach.

Yes, I also believe you just need a Amp that can basically Arc weld, which reminds me of the Electronics Kinetics Eagle 2C amp I use to own back in the day that had a cult following. That was definitely an arc welder, lol.

Trying things for yourself is just wrong. You could be defying the opinions of audiophiles who's impeccable tastes have been developed through years of gear swapping and tweaking, some going without food for days to pay for a more revealing $1,200 power cord. By enjoying music on your own played through gear choices not approved by the "unseen hand" of the audio Seekers of Absolute Truth, you risk having fun at their expense, and do you really want to generate that sort of enmity? To enjoy home audio experimentation with inexpensive used gear, single wired speakers, class d amps, untreated wall surfaces, or a lack of sufficiently clean AC current is clearly a fool's game and will certainly lead to chaos and the end of the world as we know it.
