The actual USB playback is done by a Raspbeery Pi with Volumio installed. It is powered by and sends USB signal to an Ifi iUSB nano usb regenerator. I use Wireworld Ultraviolet cables, found them to be good performance/cost ratio. It was until I changed the power cables with Chord Power cables for both this NAD power amp and the Audiolab DAC/preamp when I realised the true potential of the sound coming from this amplifier. semi truck air brake service

The clean sound and the use of bi amp speakers with 150 per output times 4. Infinity 8.2 plus power hungry speakers. 150 to the woofer and 150 to the upper range. 300 watts total the speaker come alive.!!!

There are no regerts.

Anthem 1 Integrated (takes too long to warm up and I do not want to have to worry about tube changing from time to time) and the Audio Analogue Puccini SE (not up to the job). The Super XV was the clear winner. And its solidly built. So I expect to have it with me for many years. Highly recommended if you have difficult speakers.

Yey! I'm so happy with the content. Thank you sushi restaurants in hyde park cincinnati

none so far

It significantly overpowers everything else and hurts your hearing, and you'll need to adjust your settings extensively to compensate. However, once adjusted, these speakers sound unlike anything else I've ever heard. Cheers from the best drywall company in Wilmington.

none as of now

But with some songs, it completely overpowers anything else, and it just hurts your ears, and you'll have to tweak your settings a lot to deal with this. However, once tweaked, these speakers again sound unparalleled to anything else I've heard. Savannah mobile truck engine repair

I have 4x citation enjoying every moment with them 3 used in cinema one for stereo system . No complaints. Run cool under high stress. Fully recommen if you get chance to buy . Buy quick it sell like hot cake.

It is very hard to lift nearly 40kg

Perfection, I have 2 one of them clips when I turn the preamp on, but is a minor problem to switch it on again. More than 10 years of great sound

Weight is a hassle to move them.

I have used this amp a couple of times in my system over the past 20 years and it never ceases to amaze me. First let me say if you have issues with bass, it's not this amp. I use Platinum Audio Solos that have 4" aluminum bass drivers and the bass is deep, tight, fast and well controlled with the amp in bridge mode. (450 wpc) . In any system, if your front end is mid fi, then your end sound will be mid fi or worse. Even with the advances in technology, I've yet to hear an all in one box CD player under 5k that will sound better than a 2k outboard dac and mediocre CD player combo. Cheap cabling also results in less than stellar sound.
I find this amp paired with a PS Audio DirectStream Dac, Classe CP 60 pre and a Bel Canto CD 2 with Transparent music link cables to sound outstanding and on par with the Levinson 300 series amps. This amp is above average in 4 channel, but when switched to bridge mode, it's sonic charrsteristics really begin to bloom. It has some of the sweetest midrange and top end of heard in any SS amp regardless of price. Reminds me a lot of the Proceed Amp 2 which is a phenomenal amp for the money as well. At 600.00 - 800.00 on the used market, you'll be hard pressed to find anything under 4K new that will touch it, providing you are using good front end equipment and cabling. In my system, out of all the amps I have owned, ive only heard 2 amps that bettered this citation in terms of resolution and overall transparency and those 2 are the Krell KSA 80 and the ARC 200.2. My only complaints are: (1) this amp weighs over 85lbs and is not easy to move because of no handles and (2) no balanced XLR inputs.
In summary, there is nothing on the used market under 2k that will produce the sonic signature this Citation does. One of my top 3 all time favorite amps.

Very clear and extended frequency response, vocals sound very lifelike, and the upper end is very smooth and sweet, splashy in a good way and very accurate. No glare or listening fatigue whatsoever. Makes those CDs I have that always sounded "hard" very enjoyable to listen to now. Always thought it might have been a speaker issue or maybe cables, but the glare was from the Rotel 1080 I was using. Very nice soundstage. Basically I feel the Citation 7.1 does everything right from about 1kH and up. The bass is deep and powerful, but nowhere near as tight and evenly controlled as the bass response of the Rotel RB-1080 I intended to replace. Plus, it seems like the bass is kind of emphasized around the 100Hz mark, and the lower midrange @300-800Hz seems a little scooped, losing some of the grunt and body of electric guitars. Almost makes rock music sound thin and "polite" when combined with the very smooth upper end. I am running Paradigm Ref 100's (v2) and everything including the powercord was the same between the two comparisons. I have loved the Rotel 1080 since day one, but it has always been a little edgy and fatiguing for me particularly at very high volumes on less then perfectly recorded/mastered material. The 7.1 definitely took care of the glare problem and showed me what the paradigms were truly capable of from the upper midrange to the very top of their frequency response, and ended my idea of needing a speaker upgrade. Now I need to find an amp that combines the 1kH and below of the Rotel 1080 (which is perfectly balanced, tight, gutsy, and authoritative in that region) with the 1kh and above of the 7.1 which is very smooth and detailed. Sure I could biamp with both and might just play around with it, but would much rather have a one-box solution that can do it all.

Long story short, if you have very capable full range floor standing speakers, you may be missing out on their true bass potential by using the 7.1. (By the way, I am using the CItation in UNBRIDGED mode).
I never thought I could be the guy who could "hear" differences in amplifiers, but I think this is more a testament to the neutrality of the paradigms which will pretty much give right to you what they are given. I owned a Citation 7.0 processor for many years and was enamored with it, and always wondered about the 7.1 amplifier, and only just recently thought about doing the speaker/amp upgrade thing to see if I can get better sound. Now I am on a mission to get the best of both the 7.1 and 1080's worlds in the same amp. (I currently use a Cary Cinema 11 for a Pre/Pro).
