Hello, I would like to know who else has ATC speakers. It would be great to share setups and experiences. My current setup: Lindemann Musicbook 20 DSD > ATC EL 150A I may upgrade my DAC, right now looking for something new and exciting. Current considerations include Denafrips Terminator, dCS Bartok, Mola Mola Tambaqui and Linnenberg Satie. Thanks and happy listening. Mev
Hello. I'm selling my XEO 3s (white, up on eBay now!) and getting the XEO 20s. I think! I started down the path of exploring a direct USB connection to the XEOs, but not necessarily wanting or needing the Dynaudio Connect box. Then I came across a review of the KEF LS50 wireless, where an external DAC was used, I think via the analog outs. It sounded like using an analog out would be odd with the XEOs, as a digital signal stays digital until the driver, and an analog signal is converted to digital by the XEOs. So with analog DAC out, the digital signal would be converted 2x, if I understand correctly. Any thoughts on the following setups— With DAC 1. iPhone + ALAC files > Apple CCK > USB cable > External DAC > Toslink from DAC to XEO 20 master. 2. iPhone + ALAC files > Apple CCK > USB cable > External DAC > Analog out from DAC to XEO 20 master. No DAC 3. iPhone + ALAC files > Apple Lightning Dock > Toslink to XEO 20s (I think Apple's Lightning Dock bypasses the iPhone DAC when using Toslink and sends a pure signal.) On my setup, I'm thinking of using my iPhone 7 (gasp!) for the source. Don't really want to deal with a headless Mac mini (+ controlling Apple Music would be a pain). I was looking at the Aries Mini, as you can add storage, but it's sold out. Bluesound Node 2 doesn't work with Apple Music. Sources are ALAC and Apple Music for the mist part. Maybe Tidal at some point. So as much as it may offend, I like the idea of a iPhone or iPad as source. Thoughts?
Hi everyone, I am in the process of completing my audio chain setup. I've recently purchased a pair of Genelec 8040B studio monitors a few months ago and recently decided to upgrade my basic audio interface to a well regarded DAC. I've purchased the denafrips ARES DAC which is on the way and I'm in the amidst of researching how I can match all components including purchasing new cables. Questions at the bottom of the post. Due to the fact that the ARES has no built in pre-amp or attenuator I am in the hunt for most likely a passive Preamp with balanced Input/output placed immediately after the DAC. However given the technical specifications below particularly on impedance matching and the idea that the ARES outputs a relatively high output impendence, I am also open on the possibility of adding an active solid state pre-amp. Finally, from the research I've done, it may be that a passive preamp with a buffer integrated or added right before it may be the component I would need to convert a higher impedance signal and output a lower impedance signal. This is because I may have some impedance mismatching involved however I would like some feedback on that. The reason why I am slightly concerned is the general rule from what I've read across the web states that the input impedance of the power amplifier (in this case the built in amplifier in the studio monitors) should be roughly 10 times the output impedance of the source to ensure no roll-off in high frequencies or loss of dynamics. In the case of my active studio monitors, "the audio input is via a 10 kOhm balanced XLR connector", so I'm assuming that is of course the input impedance required to be matched right before the amplifier section. Here is my proposed chain in simplified terms: Razer Blade Laptop >> USB cable >> ARES DAC >> Solid State Buffer? >> Passive Pre-amp (balanced Input/Output) >> Genelec Active Studio Monitors From https://www.genelec.com/answers-library#qid-926 "I have no preamp outputs on my equipment. Can I connect my monitors to the speaker outputs of my power amplifier?" It seems the circuitry to the Genelec's amplifier is quite non-trivial as compared to a individual amplifier. In the answer, they advise to never connect a power amplifier output to the monitor as the input stage would be damaged, however it seems a typical passive pre-amp with an attenuator would be fine. Finally here are the specifications I am working with to ensure proper matching: ARES DAC Specs: Analog Output: XLR at 4.4Vrms +-10% (Peak voltage calculated to be 6.22 volts) Output Impedance of 1250 Ohms Genelec 8040B Spec: Crossover Section: 10 kOhm input impedance Input level for maximum short term output of 100 cB SPL @ 1 M: Adjustable +6 to -6 dBu Mains voltage:? 100,120, 220, or 230 V according to region - not exactly sure what this is. According to this paper: http://www.decware.com/paper55.htm In order to select an ideal preamp I must know 1. The output voltage of the source (DAC) which is 4.4Vrms 2. The input sensitivity of my amplifier - I am not sure what this is number is. From basic electronics, it seems like my DAC has adequate line stage voltage (should be at least 2V), and need to find he input sensitivity of the Genelecs expressed in volt, the Tortuga website mentions most amps have sufficient input sensitivity, so it maybe I don't need to amplify the signal twice. What Tortuga does mention is regards to problems with passive pre-amp is this: https://www.tortugaaudio.com/what-is-a-passive-preamplifier/ "Using a passive preamp between a high impendence source (ARES-1250 Ohms) and a low impedance source (Genelec - 10,000 Ohms) may overwhelm the ability of the source to drive audio signal without negative effects (dynamics and punch)." Lastly, they mention high capacitance of cables (in my case all XLR) is highly detrimental and can add considerable impedance to the audio signal so as to act as a low pass filter, rolling off higher frequencies which I don't want either. A high capacitance cable is of the order of 50 pF/ft while a low one is of 20 pF/ft. Questions I have are 1. Given, the parameters, what kind of attenuating section should I invest in, an active pre-amp or a passive pre-amp? Do the input and output impedances matter, and if they do, what ranges on input and output impedances do you recommend for the pre-amp. 2. How short do I need the upstream XLR cables to be, how short should the downstream cables be (running between the pre-amp and the speakers). 3. What are some good XLR cables with capacitance as low as 20 pF/ft you can suggest? 4. What are some good passive pre-amps if I need that type? 5. Do I need to invest in a buffer to ensure proper matching, what does the buffer look like and where can I purchase one? 6. Is the setup workable in the end without compromising my listening experience? The post is a little overboard with content, however I would like to be thorough for myself as well as others if they come across this. It would preferable in the end to not introduce any colorization (like tube pre-amps or buffers) and to keep it simple so as to pretend the original musical signal from the DAC is unaltered. Any technical input or subjective experience for a suggestion of components would be most helpful. Thanks.
Does anyone on this board have any experience/familiarity with Edifier’s products, especially their powered/active speakers? They appear to be attractive technologically and definitely price-wise. The company seems to have relatively recently entered the US market (via Amazon) and appears to be popular in Asia (based in China) and Europe. They seem to be well liked among posters on HeadFi. In addition the blogger Digital Stereophony http://digitalstereophony.blogspot.com/ has performed some interesting speaker comparisons where Edifier speakers came out well. Based on his recent test (vs. JBL LSR305, Klipsch R15 - PM) of Edifier’s S2000 Pro (incl. DAC/DSP) this seems like a serious performer for the price. Not reviewed is the lower priced S1000DB (w/o DAC). However, except for good reviews on Amazon I’m reluctant to take the plunge despite what otherwise seems to be the real deal. Other speakers in the running: Vanatoo T0 (w/a sub) & T1; Audioengine HD6; Peachtree M24; JBL LSR305; Klipsch R15-PM. Any insight would be appreciated.
