  1. Yes we must remember that the review is of passive version so the power amp used in this review has massive effect on the end result. About the vocals… when I first heard 40’s in 2014 (current model with curved cabinets) it was a real eye… or should I say ear-opener. I came from PMC GB1 and before 40’s, PMC 20.21. With modest Naim SN2 integrated amp, 40’s simply destroyed the 20.21’s. And the difference was mostly in the midrange (and low end extension obviously). But what struck me most was the amazing midrange clarity and vocals. With PMC two-way design you can’t even touch the delicateness and detail of ATC midrange. It felt like you’d be lacking a massive amount of information with PMC. Like you’d be listening to only highs and lows… just miserable in comparison. After that I’ve been all-in with ATC. Even the most expensive exhibition demos haven’t turned my head.
  2. Well explained Nopiano. Sealed box design offers such speed and agility that some might perceive it as dryness. Reflex port designs can sound looser and more relaxed but have never the same speed and bass detail than sealed box. Then again, ATC uses front firing reflex port for the classic line and they still sound extremely fast and agile. Maybe the extra power on classics and s-specced drivers make this possible.
  3. Good review, read it today also. About the dryness. Having owned both, passive 40’s (reviewed here) and active 40’s. I must say that going active certainly helps with the slight dryness people might experience with 40’s. With actives the power reserve is so great that especially the low end power and dynamics give you little bit more ”beef around the bones” for the sound, if you know what I’m saying.
  4. I got the same error and added this line also and it works now. Thank you entdgc, great little tool to visualize what SO2 does! EDIT: I'm little surprised to see that there's two notches which go very deep for my right side speaker which is located quite close to the corner. One at 39hz and other at 77hz and with around -15dB. For left side speaker which is nowhere near the corners but also pretty close to the front wall, the cuts go as deep as -13,7dB for 74hz. These are very deep cuts(?) but I guess it is what it is when the listening room is concrete cube. Anyway the music I'm hearing with SO2 on is so much better than with it turned off. EDIT2: I did some frequency sweeps and SO2 pretty much gets it right. Those deep cut frequencies are still audible but at the same/similar level than rest of the bass frequencies. If I turn SO2 off, those deep cut frequencies play ridiculously loud and wake up mods, especially around 75-79hz.
  5. As beautiful setup as always Craigas. What caught my eye though is absence of curtains on the window behind your setup. Maybe try some thick curtains there, at least in the corners? I bet there would be some audible improvements.
  6. I’ve used ATC speakers as my main speakers since 2014. First pair was passive 40’s (current model) which I used as part of my midrange Naim-setup (Naim DAC + TeddyXPS to SuperNait2 + HCDR/TeddyCap). Early 2019 I replaced my whole setup when I went active with 40A’s. In this process I also had 19A’s in home demo for two weeks and I went through ~half a dozen dac-preamps to potentially front my future active speakers. I went for Linn Akurate DSM/3 in the end. ATC fever got so bad that early this year I ordered 50ASL’s and have been using these for two months now. These are my endgame speakers, just absolutely stunning sound quality. Depth and realism are on next level compared to 40A. Extra 10hz reach on low end does wonders also. All of these speakers have been extremely good. Passive 40 simply destroyed PMC 20.21 I had before and I compared them with few other models also while I owned them but always preferred ATC sound. The biggest improvement was switching from passive 40 to active. I couldn’t believe these were the same speakers but just active version. So much more power, dynamics, bass… everything on another level. After using 40’s with my Naim setup for five years, I only now realised how underpowered SN2 with 80W (vs ~230W with actives) had been for them. Now I read many people describing entry-series ATC’s lacking in bass and smoothing highs too much. Passive 40’s almost always sounded smooth from top end but not lacking. With wrong component matching I was even able to make the top end sound shrill and fatiguing. Neither did I feel they lacked bass until I heard the active version. Active version hit so much lower and with more power that I couldn’t use them in the same space I used passives without heavy room treatment or some room correction. This is actually a big reason I chose Linn with Space Optimisation - problem solved. Also you have to remember that entry series is closed box design so the bass is always tight, controlled and hits different compared to reflex port designs. What I’m trying to say is the big cliche of ”go active” with ATC’s. It really is the easiest way, and in the end also financially the smartest way. If not possible like with 11’s, choose very powerful amp. ATC makes great amps with pretty reasonable price tag so I’d naturally look there.
  7. I’m from Finland so I have a clue But the worst case here in our rather new apartment building was around 18c inside bedroom last winter. Nice temperature for sleeping. I’ve just made two presets to SO for regular temp/humidity and other one for warmer and more humid. One for winter would probably be smart also since then air is very dry and cooler. It doesn’t need to be exactly right all the time, otherwise you’d need to tune the settings daily.
  8. If your apartment/house has 14c temperature inside, you definitely have more serious problems than SO.
  9. I just did the opposite and moved my QNAP NAS away from the rest of the system. Spinning HDD and fans make some noise so it’s better to keep the NAS in another room. My NAS also runs Roon core. There was zero difference in sound quality between having the NAS next to the system vs in another room. I stream over LAN and use English Electric 8Switch connected to my Linn ADSM. It’s important to use a switch before the streamer. Even basic Netgear is clearly better than no switch at all. And to answer your question, yes you want the switch between the router and SDSM. I also recommend BJC Cat6 or 6a cables to be used from router to switch and from switch to SDSM.
  10. I've never heard Innuos in my own setup so I can't comment on that. 2.0 looks promising on pictures.
  11. If the difference is obvious then quick switching works very well. Sometimes I leave a component on place for few weeks and then switch back to old configuration to see if there's really a difference. This method worked with power cords and revealed differences in the end. Last time quick switching revealed something on Roon vs UPnP but not this time. Back in the day when I was making the decision for Roon, I compared it against JRiver Media Center, which was my main application for music library back then. There was clear difference between these two applications but my setup was completely different back then. I connected my PC to rest of the setup through USB bridge (Mutec MC-3+ USB). JRMC sounded slightly fuller with rounder/fatter bottom while Roon was slightly clearer sounding. First I preferred JRMC and that's the reason why it took me two years before I finally pulled the trigger on Roon lifetime. In the end after some other changes in my setup, I preferred Roon over JRMC.
  12. I repeated my test last week comparing Roon (core running on QNAP NAS) vs Linn Kazoo upnp server running on same NAS. Streamer/dac/pre was Linn ADSM and speakers ATC SCM50ASL. I could quickly switch between these two streaming options since they were running simultaneously on QNAP. This time I heard zero difference between the two. Last time I did the comparison with ATC 40A’s and back then I heard (or thought I heard) a difference. Now with better speakers, no difference. Weird stuff.
  13. Well I’ve also learned that everything’s possible in this hobby but in this case I’m highly skeptical. I actually run my NAS in another room. I first had it in the equipment rack but couldn’t hear any difference in SQ after moving it to the office so I left it there. This also eliminated the HDD and fan noise at the living room. NUC with i3 and silent Akasa case would be around ~300 euros so not an impossible investment just to try out though.
  14. Yeah with 4gb it ran out of memory very quickly. This hasn’t happened with 8gb of RAM. Roon likes plenty of RAM. The CPU is also underspecced (according to Roon) but it still runs the core with ease. CPU runs under 5% when playing music. I also run Plex server on the NAS for movies and occasional listening to my library when on the go. Some people report sound quality improvements with NUC but I can’t see how that would happen.
  15. So what kind of improvements have you guys noticed after moving Roon core from NAS to NUC? I run Roon on QNAP TS-253D with zero issues. I just added another 4gb of RAM to it making it total of 8gb. I’ve also thought about adding NUC in the mix running Roon Rock but I just don’t see any reason to it since everything works perfectly as is. Still many people make this move… why?
