Hello everyone!
First of all, I would like to apologize if my English is not perfect, this is not my language. I just hope you will be able to understand my questions.
I am reading Audio Science Review since more than 1 year now and I really enjoy all the work performed here. My background is chemistry, not physics, but I recognize myself in the mindset expressed here. However I have several question to raise to the community...
I will perform a lot of upgrades in my house, and this will includes installation of a Home Theater system (7.2.4) with integration in the ceiling/wall of some components. My intend is also to listen music, and I would like to be able to read Hi-Res music (and switch from Deezer to Qobuz). Before discovering ASR, I visited a lot of forum and read a lot of so call review (in fact subjective comments), all going in the same direction if you take a step back: more expensive it is, the better it is, but no technical assesment so far... so thank you @amirm for creating this site!!
I have seen last reviews of DAC, reaching high level value of SINAD, but I have the following question:
1) Whatever the quality of a DAC you could have, in your living room, where you cannot do (or on a very limited way) accoustic treatment, according to Amir, the first step to improve quality of the sound is room EQ. But if we plug a wonderfull DAC and link it to an AVR, anyhow, to have room EQ, you will need to go into the digital pipe of the amplifier to get your correction, no? So what is the value to put a desktop DAC with high level SINAD as an input to your AVR? Except in Pure mode (where you don't have Room EQ), this is a waste of money, no?
And if I understand properly, among all the Home Theater devices tested so far, no one get better than 105 dB SINAD, correct?
2) Streaming music has changed the way I listen music, we are able to spend hours testing and listening music, navigating in so huge database we can loose ourselves. Doing this with a tablet in your sofa is so great... but I have a question concerning this: most of the time, the tablet is "reading" the music and send it to the amplifier with limitation (I know Airplay is limited to 16 bits). But some manufacturers propose (Arcam for example) solutions where the amplifier is reading the music in Hi-Res with a connexion to your streaming account, and the tablet is only "controling" the amplifier. Have some of you tested this way of working? Can we get full benefits of the Hi-Res or is it "snake oil"? (if I use an expression I have discovered here
3) As a lot of people on this forum have decided to get a Denon 3700 and to use it a pre-pro. I am considering this solution also, but this AVR is only proposing RCA outputs. On the amplifiers I am considering (based on Purifi modules or Hypex Ncore modules), they propose mostly XLR inputs. Is there a problem (other than the power issue to send only between 1 to 1,5V to the amplifier) or a degradation in the the signal to use a RCA/XLR cable converter?
4) As explained I am considering to deploy a 7.2.4 system. I currently have an 400W amplified sub (B&W PV1D) and I am considering to add a 1000W amplified sub (I did not made my choice on the model yet). Did some of you had issue with Audissey XT 32 associating two subs with a large difference of power? Do Audissey know how to manage 2 sub separatly?
5) I have understood all the measurements performed by Amir on electronic with the help of tutorials explaining all the graphs, how to read it, what is the idea behind the test etc... Is there a post explaining the same for the speakers tests? I failed to find it and I have difficulties to assess if the results are good or not and why....
Thanks a lot for your time and thank you @amirm for your work!
I hope I will have answers!
I wish you all the best!
