Bryston VS Musical Fidelity

Ayre V3. Thanks, Lrsky.

There's a new idea worth considering Greg_lett. In my time knowing Lrsky, he usually comes up with an idea ot two that could significantly change your system for the better.

Tvad,

Indeed the choices are endless. Wht you say about equipment
matching is also true. The reason I through a Rotel amp
into the mix is because I have:
Rotel RCD-1072 (CD Player)
Rotel RC-1090 (pre-amp).
I owned the RB-1080 also, but I sold that in order to upgrade
to the 1090. I did that because I heard a significant difference (for the better) in my system using the two old Rotels I'm currently using. As I stated earlier things came up so that got delayed, and I figure I would look at other amps.
The choices as you said are endless. I know if I get an
amp other than Rotel I would want to change out my other gear to match that brand. I know you don't necessarily have to do that, but I guess the products from the same maker should go well together, one would hope.

Gregg, I just purchased a pair of CI Audio D100 mono amps to audition. Right out of the box, I'd say they are comparable to my old Bryston 4B SST. Clear and punchy. Currently playing @ 99dB through my VR4 SE loudspeakers measured at my listening position 8 feet from the speakers.

Given the price of $1599, these are a no-brainer over a 4B SST, and I venture to guess the Rotel as well. Have you ever measured the decibel level from your listening position? It might give you some insight into how much power you actually use. Radio Shack Db meters run about $50, or less.

Tvad,

I haven't measured the db level. I will do some reading
on the CI Audio.

Gregg, the reason measuring the decibel level is helpful is it gives you a real world idea of how much power is required to drive your speakers to what you consider "loud". Check your speaker's sensitivity. Mine are 89dB measured at 1 meter and 1 watt of power. Each time you double the power output, the speakers play 3dB louder. So, for my speakers to play at 92dB, I require 2 watts of power. 95dB requires 4 watts, 98 dB requires 8 watts, and so forth. Extrapolating the curve out, I require 32 watts for my speakers to play at 104dB. At 104 dB I can't be in the room for very long. On the other hand, 110 db requires 128 wpc. So, the power requirement increases exponentially versus decibel level. You can do the same for your speakers. Just start with your speaker's sensitivity rating and add 3dB for each doubling of power starting with 1 watt (assuming your speakers are measured 1 watt/ 1 meter...most are).

I mention this because you may find you don't require as much power as you thought. 100wpc may be plenty. 200wpc may add some weight and headroom, but I'll bet you never use it.
