Why monoblocks?


Why run monoblocks? Most amps can handle most speakers, especially those that are 88DB and above in sensitivity. I see pictures of all these speakers being driven in monblock configuration. If the stereo amp can do the job, why spend money on two amps? I mean, what are the benefits?

First of all you get more power supply with mono amplifiers and there is a huge advantage to the left and right channels having separate power supplies.

Sonically there is a noticable improvement in separation and the soundstage is much larger with mono amplifiers. The same is true with mono or dual mono preamps.

I have achieved some of my best sounds with mono amplifiers with long interconnects and short speaker cables.

I really don't care how it looks.
Foster_9, Just do it. You will be glad you did. Bigger soundstage and images, better dynamics and better overall sound.

Most audiophiles buy stereo amplifiers because it is cheaper than buying monos.
Statman, This is exactly what I was talking about. The Classic 120s actually have twice the power of the Classic 60. I have owned both and both are great amps. You forgot to mention the soundstage was bigger with the monos.

Audiofeil, I did the 300B thing and decided it didn't work since those amplifiers are not capable of driving real world speakers.

And speaking of inexperience, you may think VAC amplifiers are something special, but it wasn't that long ago VAC was not a well received product because of competition like the Audio Research Classic 120 which was a much more flexible and better sounding amplifier on a broader range of speakers.

At the same time, VAC was marketing Chinese tubes under the name Golden Dragon. These are the tubes that were used in VAC products. We called them Chinese firecrackers because of their short life expectancy.

I always buy equipment from reputable companies and as a rule mono amplifiers will give superior sound and that is a fact.
Kclone, He is using a Mark Levinson stereo amp and he wants to go back to monos.

My comment was not negative toward VAC or Mr. Hayes. I was commenting on the market regarding specific products. I have no personal interest in any product at this time.

What was I thinking? I thought we were comparing apples to apples. I'm not talking about comparing $800 monos to an $8,000 stereo amplifier. I am referring to comparing like products.

Most audiophiles buy stereo amps because they are less expensive and manufacturers reserve their best for mono amplifier designs which dramatically increases the price.

I understand there are exceptions to every rule, but I believe today's audiophile would rather spend money on a dozen expensive power cords and power conditioners than a pair of high quality mono amplifiers in an effort to improve the sound.

If this was not considered an advantage why do we have dual mono designs in amplifiers and preamps? I realize there is such a thing as personal taste, but when a system sounds good everybody agrees.

Minor1, I totally agree.
