[EVOLVIST]

As much as I know, reading the specs, looking at different models, monoblocks, integrated stereo amps, etc., it seems that all of these models until the recent Etude, is the same topology, the same guts, power supply, and measurements, going back to 20 years, the only difference seems to be the boxes and varying watts they put their tech into.

Could this be right? Maybe some Chord experts could assist.

Here's an example:

Let's say you have an old pair of CHORD SPA 612 Monoblocks - rackmounted model

FREQUENCY RESPONSE: –1dB, 0.2Hz to 44KHz. –3dB, 0.1Hz to 77KHz.
SIGNAL TO NOISE RATIO: BETTER THAN –103dB. ‘A’ WEIGHTED TWO-THIRDS POWER.
HARMONIC DISTORTION (THD+N) BETTER THAN –75dB
CHANNEL SEPARATION: -95dB

Now the new Ultra Series Monoblocks

Frequency Response:

-1dB @ 0.2Hz to 46kHz and -3dB 0.1Hz to 200kHz

Signal to Noise Ratio:

Better than -84dB

Channel Separation:

Better than 90dB

It doesn't even give the THD+N for the new one. It seems pretty comparable across the board, with the older model having slightly better signal to noise, and slightly better channel separation, yeah?

As far as the frequency response, gee, what does the difference between 77kHz vs. 200Khz even matter?

So, yeah, this is just one example out of many looking at Chord specs for amps over the years. You find may such comparisons between models, some that probably are a closer match, even.

I'm just wondering what's the skinny, you know?
