    The advantage of the "moving mic" RTA for EQ is that it'll take into account head movements by capturing a slightly wider listening window than the stationary mic. Narrow high-Q filters may also be counterproductive for the same reason. In my room there isn't much difference anyway: Left speaker (psychoacoustic smoothing) - top curve (green) sweep, bottom curve "moving mic" RTA (red)

    Can you rephrase that? I don't see where the SoX came from. You can oversample/upconvert and filter with software or using the DACs internal ASRC and filter. By the way, even if your DAC cannot be run NOS and filterless it may still (and probably will) perform and sound better if you oversample and filter with software (provided that you use the right software).

    Do your “standards” go higher as you upgrade?

    It's been a while since I last went to a show or demo. I remember being positively impressed by an all TAD Reference system with the Ones. My current reference is a friend's system consisting of a highly modified 338ESD or PD-91 or his own DAC, his own transistor amplifier and a pair of modified 801Fs. Listening to it for the first time was a mind blowing experience and has convinced me that everything does matter even if the degree of influence varies massively depending on the element involved. Unlike most commercial electronics the amplifier has been a work-in-progress, suffering constant development for almost two decades. The level dedication, research and experimentation invested in the system would have made it commercially inviable. In my experience there's only so much that commercial electronic equipment can offer. Speakers are a more complicated matter though.

    If you upcovert with A+ then you should use the NOS mode (called ultra-slow?). No point in duplicating the filtering.

    If the DAC chip is SDM then this conversion will happen anyway. With HQ Player I can use an EQ filter made with REW (a couple of peaks below 100Hz) and upconvert to DSD. This way I can bypass the DACs ASRC and filtering and feed the chip with DSD at its highest admissible sample rate. It's a win-win that is both audible and measurable.

    That's how I use my TEAC. I upconvert from PCM - mostly Redbook - to DSD 128 with HQ Player and use the DAC in NOS mode.

    "Bright" equipment may give an impression of detail but this is not the result of a higher ability to resolve low-level detail. Unfortunately it's become fashionable for manufacturers to design "bright-sounding" speakers and this has led to many people associating "resolving power" with "hardness" and too much treble. A real high-resolution system or equipment will sound detailed when playing at low levels and smooth-sounding when played loud. Such systems can be used at much higher SPLs without causing tiredness but will retain detail when played at low levels.

    Ken Ishiwata leaves Marantz

    Ken Ishiwata: Forty years of preserving the Marantz sound https://www.whathifi.com/features/ken-ishiwata-forty-years-of-preserving-the-marantz-sound How did you end up at Marantz? Actually, Marantz Europe contacted me in 1977, as they needed someone technical who also understood European business. I went there for an interview, but when I gave my conditions they said, "Mr. Ishiwata, you are too expensive for us." I didn’t want to compromise, so I went home and forgot about it. A couple of months later they contacted me again and said, "We can’t afford to have you in the European organisation, but Marantz Japan still want you to join the company." After that, I joined the company in 1978 as tech/commercial coordinator.

    Dual sub placement- in corners or beside speakers?

    I agree. But because most people don't measure I think that it's a good rule to follow unless the manufacturer states otherwise.

    Are you keeping your old stuff alive?

    I agree with that. The exception being the DAC, which you've updated to a more recent model.

    Are you keeping your old stuff alive?

    I keep an old Sony and a Behringer UCA as backup. I find no use in collecting gear and I'd rather spend all of my meager budget on a single main system. I borrow my son's Bluetooth JBL if I feel like a bit of background music when I'm cooking. PS I've been keeping my CD player at my parents. I intend to sell it but it has been modified and that makes it less appealing.

    Can you place them against the side walls, one on each side? You can use a piece of string to draw an imaginary arc centered on the listening spot and stretching to the speakers; where this arc meets the side walls is where the subs will be roughly time-aligned (I am assuming that they're sealed). P.S. They should not be placed halfway along any wall.

    Took the plunge again....Harbeth & Sugden

    Why don't you buy used?

    Harbeth or Revel

    Ah, I see. I acknowledged that yours was a good approach to selecting speakers, so I quoted you, and suggested an alternative that is also (almost as) effective if people are willing to buy used.
