Me: If I already have SR6011 and Dali Zensor 7, is that enough for a good audio quality listening?\n\nMarantz: While the SR6011 will give clean enough results with your speakers in terms of general quality, the receiver will not be able to give the same kind of dynamic performance that you would get from the PM amplifiers.\n\nThe PM amplifier will provide better performance, however it would not be £1000 of a difference in quality between the two products.\n\nThe best advice I can give is to consult with a retailer who will be able to demo the equipment for you so you can listen to it and trust your own ears.\n\nSincerely,\nMarantz Customer Support\n\nHope so you will not blame me, at least no very greatly for my desire :)\nAnd till now my only option for the stereo amplifier is Lyngdorf TDAI-2170.\n\nAgain, I keep very much to thank you all for all yours help&advices!\n\nHope so, this time i could explain better than till now.\n\nBest regards.\n\n\n\n\nThe reply from Marantz is as expected as they want to sell the PM series for the much higher profit margin. From what we know so far from your posts:\n\nListening habit and environment - small to medium size room, mostly listening at lower SPL (sound pressure level)\n\nEquipment preference - Always want an integrated amp for music listening\nInfluence - Probably by subjective reviews online, forum talks, manufacturer customer supports etc.\nSubwoofer experience - Not good, but the sub tried was a bass reflex type made by Dali.\n\nNow look at some facts:\n\nListening at low SPL means more power will not likely change anything because the speakers will not be taking much power to begin with, unless and until you crank the volume right up.\n\nCustomer support is not the best place to ask the kind of questions you are asking. Think about it, what do you expect them to say other than telling your they have better components and specs and should therefore sound better? Actually they could have told you that for 2 channel listening, the SR6011 can provide much more power than the PM6005 or even the PM8005. The PM8005 is only rated 100W into 4 ohms. On the test bench it could probably do a little more, say 135-140W. It is at least limited by the smaller power supply that is designed for 2 channels. They will not be more dynamic than the more powerful SR6011 in two channel stereo, otherwise it would defy science.\n\nI copied the comparison table of bench test data (all by Sound and Vision) that I posted on another thread, you can see that the SR6006, the predecessor of your SR6011, was benched tested to 157W X2 at 0.1% THD, at 1% THD it was able to produce almost 200WX2. \n\nhttp:\/\/www.soundandvision.com\/content\/marantz-sr6006-av-receiver-ht-labs-measures#zoZE7CwGCTLjp8Ku.97\n\nRegarding your not so good experience with the subwoofer, you might have made some common mistake in setting it up with Audyssey. If you are to try again please do the following:\n\n- read the instruction of the sub so you know how to bypass all internal bass management features of the sub such as setting the crossover to maximum, and disable all filters if possible, and if not, set them to points where such built in filters will do the minimum. This is to avoid those features to interfere with Audyssey.\n\n- read Audyssey's online instructions and follow Marantz onscreen instruction, to the letter, when running it through all 8 positions.\n\nThat Dali subwoofer you had tried before was a bass reflex type, you will likely find the sealed type such as the low budget SVS SB1000's sound tighter and more musical.\n\nThe integrated amp you are thinking of buying will not give you more power than the SR6011 for 2 channel applications. In a "blind" test, I am quite sure most people will not be able to tell the difference between it and the SR6011 if the comparison test is setup properly. However, if you always wanted an integrated amp, I will say this again, go for it. I have all kinds of preamp, prepro and power amps and I like them all, though I cannot honestly tell people that one sounds better than the other.\n\nMy final recommendation is, go get your dream integrated amp but do not give up on the SR6011, it is a very capable mid range AVR that is very capable of improving your in room bass response. It has a very good DAC build in and can play just about anything in digital including DSD files.
