  1. In both the 5m x 5m and 6m x 4.3m rooms mentioned I'd try to see if the SCM50 would be good enough. I'd run even a SCM19 up to 4m x 4m.
  2. I used to have both the PMC Twenty.23 and Dynaudio Contour S1.4 LE at the same time and also demoed the Dynaudio Focus 160 and PMC Twenty.24 on my system. Firstly my 23s didn't have nearly the amount of bass in the beginning as later on, they gain some bass after the run in period, which is worth considering if you can find out how much those 23s have played so far. I have not heard the Twenty5 series, but I have heard the 22, 23, and 24 in the Twenty series and due to similar size and forms I suspect the same sort of differences. To me the SPL and especially the level at which it can play strong bass is higher on both 22 and 24 than on the 23, but the balance between the bass and mid range is different. The 22 sounds leaner and the 23 and 24 much weightier in the bass. This means at low to medium volume you should get the same sort of bass weight from the 23 as from the 24, but it won't be able to match the 24 at high volume. The mid range to treble balance is also different, possibly due to a different crossover, different driver impedance, and/or the smaller driver integrating better with the tweeter because of driver dispersion. The treble sounds more open on the 22 and 24, but more balanced and cohesive on the 23. The Focus 160 didn't have as good mid range as the PMCs in my opinion, but the Contour S1.4 LE did. Both these Dynaudios had bags of bass weight, but were more dependent on the room than the PMCs. In an open space with at least 1m behind them, they would more or less match the PMC floor standers, perhaps slightly stronger for the LE, but when placed say 70cm from a back wall, they thunder and the bass overpowers everything on the Dynaudios. They sound too light with the plugs in the ports, so I'd say they either need semi plugs for the ports, or a large space behind them. The PMCs didn't change nearly as much when moving further or closer to a back wall.
  3. @yannakout did you get something? From your description the ATC SCM 19 sounds like a good fit. @padre_power where did you get a pair? I have not seen those being sold in Australia, only in Europe.
  4. Does anyone know when the Electrocompaniet ECI 80D is ever going to get to Australia?
  5. Could you please elaborate on Very good 7/10 a bit? Does it have any scratches? Any smudges around the knobs? I can't quite make it out from the pictures.
  6. I meant to help out, as the seller might not get any interest in the Audio section.
  7. This is not audio related, and would be better under https://www.stereo.net.au/forums/forum/16-classifieds-all-other/
  8. I also used a large diaphragm condenser mic. It was definitely warmed up, but I wouldn't dismiss the possibility of noise. They weren't that far from the corners, so were definitely reinforced by the walls.
  9. My ATC SCM 19s are -6db at 54Hz, but ATC measures their speakers in the middle of a large warehouse. In my room I get the average level down to around 25Hz. Here is my response graph at the listening position: (I have room modes to sort out)
  10. Maybe also if it's long enough, but the higher category cables can handle longer distances than lower category ones.
  11. Make sure it does have both tuner and blue tooth, both of these are add on cards and not every ND5 XS has either of these. My ND5 XS has the tuner module but not the blue tooth for example.
  12. I use IsoTek EVO3 Sequel cables and EVO3 Sirius board on my Naim system and used to have the EVO3 Premier with EVO3 Polaris. I hear audible noise from my amplifier even when nothing plays, so this might make the difference between my results and someone else's. The Polaris reduced the noise by perhaps half, but also made the treble a tad louder. The Sirius reduced the noise by perhaps 75%, but didn't alter the tonal balance. I didn't notice a difference in dynamics in either. I also tried my Sirius on an Electrocompaniet ECI3 at a store and couldn't tell a difference there, so maybe either their power or the amplifier produce less noise than mine.
  13. The Naim ND5 XS came out with the option of two add on cards: one adding blue tooth, the other adding a tuner. If you have the tuner one you could listen to radio through it. It doesn't have USB input from a computer, but it does have USB for playing files from a flash drive.
  14. Hi, I'm in the south of Sydney, but the amplifier is sold now.
  15. I think that PM8006 would be more than enough, especially for the 22.
  16. Item: Rotel RA-820 Location: Sydney Price: $100 Item Condition: Worn with some marks and slight scratches Reason for selling: Replaced Payment Method: Pickup - Cash, Paypal, Bank transfer Extra Info: Specifications from https://www.hifiengine.com/manual_library/rotel/ra-820.shtml: Power output: 25 watts per channel into 8Ω (stereo) Frequency response: 10Hz to 40kHz Total harmonic distortion: 0.4% Damping factor: 20 Input sensitivity: 2.5mV (MM), 150mV (line) Signal to noise ratio: 75dB (MM), 95dB (line) Speaker load impedance: 4Ω to 16Ω Dimensions: 430 x 66 x 271mm Weight: 5.5kg This was used for PC desktop speakers driving KEF Q1 speakers. I tried it on my Spendor SP2/3R2 and it had no problem driving these. Photos:
  17. Thanks. I quite like the look of my ATC SCM 19, they definitely have a unique sound.
  18. I agree. No that is not me, I have these three: Cyrus CD Xt Signature, Stream X Signature, Pre2 DAC Qx, Stereo 200, Vienna Acoustics Beethoven baby grand SE Naim CD5 XS, ND5 XS, Nait XS2, FlatCap XS, Spendor SP2/3R2 Linn Genki, Chord 2Qute, Musical Fidelity A3.2CR, ATC SCM 19 I sold my PMC Twenty.23, so perhaps I don't qualify for this group any more, but there is a chance I might try the Twenty5.23 or Twenty5.22 one day.
  19. Bryston is made in Canada as far as I know. I think there is a misconception here. I have said from the beginning that PMC recommends Bryston, but this does not mean that I think Bryston is the best match, it just means PMC as a company prefers them. In fact I didn't like most Bryston systems I have heard in the past. The only one I did like was their 1KW mono block amplifiers, but driving Dynaudio speakers instead of PMC. I am curious about hearing a Plinius one day.
  20. I have been interested in PMC since 2014, and since then have not seen them recommend anything other than Bryston. Although they seem to be warming up to AVM. Note that this does not mean that Plinius doesn't work well with them.
  21. It sounds like a problem in your apartment circuit. The power amplifier draws more current than the pre amplifiers and source components, so that could be why only the power amplifier causes a problem. In my experience Naim amplifiers are sensitive to mains noise, and an apartment has appliances from all the neighbours plugged in close by. I found the IsoTek EVO3 Sirius to reduce this noise. I measured my wall outlet at 246V and asked Naim about that as my amplifier shows a range of 220-240V. They said it's good and have tested them on as much as 256V without any issues. I don't know what would happen if the voltage is below 220V though. It might be worthwhile checking what your outlet gives you. One last point: My apartment has only two breakers, both at 10A. This means my Hi-Fi shares power with other things in my apartment. If you only have one breaker, or have the Hi-Fi on the same circuit as other items that draw a lot of power, this could be overloading.
  22. As far as I know the old Naims, like the Chrome bumper ones, were more lively in the treble than my Nait XS2.
  23. The first person to inquire is in Sydney, so I'll only look at Pack and Send if it falls through.
