"I used Audio Precision's high-order AES17 high-pass filter when measuring distortion, as otherwise the reading would be obscured by the noise."

Hi JA, was this filter also used when measuring/presenting the (fig 9) 1kHz and (fig 10) 10kHz square wave screen shots?

Cheers George

No, the squarewave images were taken with just the external AP0025 filter as the AES17 brickwall filter would have affected the amplifier's reproduction of squarewaves. The AP0025's rolloff is sufficiently high in frequency not to have an effect other than eliminating RF noise.

Ok it's a different AP in line filter, this 20 Hz to 20 kHz passband filter you used
https://www.ap.com/wp-content/uploads/2016/04/AUX-0025.jpg
Has a -50db rolloff rate, I take it doesn't handle much power hence the "small-signal" square wave testing you can only do with it in line.

Myself, I would still prefer to see in tests with and without this filter in line, to see what's being sent to the speakers.

Cheers George

Hello Thomas,
Thanks for the review of the Classe Sigma 2200i integrated. It was interesting to read your comments about the Classe Sigma 2200i being warm sounding tonally. I personally haven't heard the Sigma 2200i but have demoed the Sigma SSP + Sigma Amp5 combo paired with B&W speakers and Wilson Sabrina multiple times and they were very neutral tonally and very transparent imo. The Sigma combo were spectacular sonically. I demoed in both stereo for music in analog / digital bypass mode as well as for home theater (surrounds).

I would assume that the Sigma 2200i would perform very similar.
Did you get to listen to the Sigma separates by any chance?

I own the Sigma SSP and Sigma Amp 5. They sound spectacular for both home theater and two-channel audio. I have a Bluesound Vault2 connected to the Sigma SSP and high-resolution two-channel audio files sound terrific.

I also heard the Sigma 2200i demonstrated with Bowers & Wilkins 804 d3 speakers at a 2016 Music Matters event at my local dealer. Sounded fantastic. Heard four or five cuts (all Redbook format, interestingly, no high res) over the course of 40 minutes.

I don't hear the "not neutral" part. Must be my faulty ears.

Hi Richard,
How did the Sigma 2200i sound compared to your Sigma SSP + Sigma Amp5 separates? What speakers do you have at home?

Too many variables to directly compare. I thought both sounded good, with no obvious flaws.

In that particular system my speakers are Sonus Faber Venere 3.0 and Venere Center with two REL S/5 subs connected speaker level with Longbow. I may eventually upgrade to Sonus Faber Olympica for L/R/C speakers, or perhaps Bowers & Wilkins 804 d3. Surround speakers are high-end Bowers & Wilkins two-way in-ceiling speakers (don't recall the model number)

I think both the B&W 804 D3 and the SONUS Faber Olympica are great speakers imo but I think the B&W 804 D3 will have better synergy with your Classe Sigma Amp5.

I myself am using the Classe SSP 800 pre pro with the Classe CA-M 300 monoblock amps (3×) for L/R/C speakers. Using the Classe CA-2300 stereo amp for my surround speakers. My front speakers are the B&W 802 D3 with the matching HTML1 center speaker. My surround speakers are the 804 D3.
