Good for you. Which model did you buy? Arcam AVR550 Nice unit as long as you don’t need balanced outs. I very highly recommend you follow the setup instructions exactly. Do not think you know better nor that you have your way of doing things unless you wish to become frustrated. Enjoy.

AVRs are complex enough that I don't assume ANYTHING. The user's guide shall be my bible.

Ive owned more then my share of Yamaha AVRs and I can tell you one real fact, Ive never mastered all the abilities of any single unit. They can be as simple or complex and powerful a tool as your willing to learn. Anyone that tells you otherwise,,,,,,Im not sure Ive ever met anyone that has mastered any single units full potential. Have fun!

Actually, from an aesthetic viewpoint, I think I prefer the Anthem to the Arcam, if for no other reason than the Anthem is available in silver. But since I encountered a good price on the Arcam, form follows function.

Previously you had mentioned the 860 which i have come to find is 8g's here in Canuckistan, too rich for my blood. I will carry on with the XMC for the time being. I have my eye on a set of aluminum heads so the audio is taking a back burner while the good weather is here.Enjoy your new toy.

Hi socketman - What fun interpreting and dissecting your post! "The 860" being, of course the Arcam AV-860 processor, "8g's" being $8,000 Canadian (did I read that right?!?). "A set of aluminum heads" being for your vehicle of choice? And "While the good weather is here" meaning not freezing? Crazy Canadians are such fun!!!

People ask us what we do during summer and i tell them we have a picnic on that day.

Yeah - I got a call from a headhunter wanting me for 36 months of work in Alaska above the Arctic Circle. I immediately declined; the hunter said "Wait - You haven't heard what I'm paying!" I replied, "I don't CARE what you're paying the answer's the same! LOL

I spent time in northern Sweden inside the Arctic circle where total sunlight hardly exceeded 3 hours. I told my team "Don't sneeze, you'll miss the day!" We are on a similar latitude as southern sweden but the north ,thats a whole different world much like norther alaska or worse. We sorta get some daylight though its not like mid day daylight you would get in southern BC . Its not for everyone but its ok.

I was born, raised, and still live @30.47 degrees latitude, and am not a fan of cold weather. I understand that "normal" is what one gets used to, but a transition from here to above the arctic circle would not be a happy one for my old carcass.

From DIRAC's website concerning their DIRAC Live correction:
What is the time-domain, and why is it important? At Dirac, we believe that the reproduction of transients is critical for a truly natural and transparent sound. For example, the stereo image is critically dependent on the time-domain differences and similarities between the sound at the left ear and the right ear. As such, Dirac’s impulse response correction improves the depth, the positioning and distinction of individual voices and instruments.
Mixed-phase room correction technology - Using a look-ahead buffer enables impulse response correction. Minimum-phase and linear-phase room correction filters can’t physically optimize the acoustic impulse response in a room. At best, they can minimize problems caused by the application of a filter. Room-acoustic responses are non-minimum-phase, which is why Dirac Live uses mixed-phase correction. Dirac Live is unique in that it improves the impulse response throughout the listening area, not just in a particular zone.
Multiple measurements - Dirac Live uses several measurement positions (typically 9) in the listening room, making it possible to accurately locate and correct acoustic problems. In terms of the impulse response, this means optimization of the direct wave and very early reflections. Generally, at higher frequencies there is less consistent time-domain behavior. Dirac Live room correction automatically finds consistent problems in a frequency-dependent way and corrects for them. After addressing consistent time-domain behavior, there may still be some late reverberation in the room that causes subtle coloration. Dirac Live corrects these in the frequency domain to achieve just the right resolution.
Impulse response correction - A loudspeaker’s impulse response affects clarity, detail and all spatial aspects of the sound. Dirac Live is unique in that it actually corrects the impulse response throughout the listening area, not just at a single point. By focusing on consistent problems across the measurement positions and correcting only these anomalies, Dirac Live can achieve a faster decay time. Typically, the power ratio between the direct wave and the tail (later-arriving echoes) is improved by 6 dB or more, representing a vastly improved overall sound.
Frequency response correction - Why is it that the same frequency response can sound so different from room to room? The answer lies to a large extent in the time-domain aspects of the measured frequency response, as well as critical differences in the spatial (angular) domain. By addressing time-domain problems as such, and not as minimum-phase spectral problems, frequency response correction becomes more effective. After having conducted time-domain correction, we then treat the spectral colorations in a room. By paying particular attention to the variations across different measurement positions – not just the average – we can make sure not to overcompensate.
Implementation for best accuracy - Traditional EQ uses IIR filters for lowest processor usage. Many room correction filters use FIR filters for ease of implementation and optimization. IIR and FIR filters both have their pros and cons. At Dirac we use a proprietary filter structure that achieves maximum performance at much less processor usage than regular FIR filters. This filter structure also has great numerical properties, and thus doesn’t produce any digital noise.
Choosing a target response - A flat frequency response does not necessarily sound neutral due to the ratio between direct and reverberant sound and the frequency-variable propagation loss. Dirac Live can’t remove late reflections, because they change too much between different positions. Therefore, a slight roll-off is often appropriate when listening at a distance. The Dirac Live algorithm suggests a target response appropriate for your listening environment and speakers, which you can of course adjust to your taste using our simple graphical interface.
Advanced, yet very simple to use - You don’t have to be a signal processing or computer expert to enjoy the benefits of Dirac Live. All of the Dirac technologies that comprise our world class digital room correction solution are automatically managed by our software, making it easy for users of all kinds. All you to do is position the microphone and press “Play” – our software wizard will take care of the rest. Advanced users are free to edit the target response as desired using a simple graphical interface. Otherwise, just press “Optimize” for the most lifelike reproduction of your favourite music!

^^Did you read that wall of text? Kidding aside, DIRAC reminds me of your processor you owned that had TACT.

No, garbulky - you mean the description of DIRAC reminds you of your experiences with TacT. Let's not confuse the description with the actual experience! I'll hold off on opinions until I hear DIRAC for myself.

I'll hold off on opinions until I hear DIRAC for myself. We've both experienced TACT and DIRAC. DIRAC was with you and NovisNick at his place with the XMC-1. TACT was at your place with the Lyngdorf. However we haven't heard DIRAC at your place. But what I was saying is that the text description of DIRAC reminds me of TACT's text description.

Yes, Nick DID have his DIRAC going when we last visited, but I couldn't make any judgment of what it might have sounded like - new room, new speakers, new electronics, and new DIRAC. Which part contributed what to the overall sonics? I've no clue. But it did all sound good! Was Nick running his XMC-1 at that time? I think he was. The Yamaha AVR was in the downstairs system... So although I've technically "heard" an XMC-1 (and DIRAC), I've no way to evaluate what those particular elements sound like because there were too many other unfamiliar variables. When the Arcam comes in, I'll be able to compare the plain vanilla Arcam sound to the Arcam sound with DIRAC. THEN I may form an opinion. So the ultimate question will end up being: "Which sounds best - The Oppo DAC with the BasX A300? The Arcam used without DIRAC? The Arcam used with DIRAC? Once the first cut is done, then the "hybrids" will have to be evaluated - Oppo DAC with Arcam amps? Arcam DAC with BasX amp? Arcam DAC with Heathkit amps? Arcam DAC with XPA-2? Hopefully, some combo will be clearly superior. If the Arcam is "at least as good as" the Oppo playing directly into the BasX, then Huzzah! If not, then a novisnick "hybrid" system will become necessary - Arcam for movies, something else for stereo. Audio amigo "Russel" claims that the Arcam will instantly destroy 80% of my system's transparency. I'm hoping he's wrong...
