Hi all, I’m trying to fully understand the DSP/EQ behavior of the Eversolo DMP-A6 Gen 2, but I’m running into conflicting information and hoping someone here can clarify. In the EQ menu, I can see options to configure EQ per output (XLR/RCA, HDMI, OPT/COAX, USB). This makes it look like DSP might be applied more broadly than just the internal player. However, I’m unsure how this actually works in practice. My questions: Is the EQ (PEQ / FIR / room correction) only applied when using the internal player (via the Eversolo app)? Or can DSP also be applied to external digital inputs like: HDMI ARC (TV) Optical / coax USB DAC input from a PC What exactly does enabling EQ on outputs (like HDMI or XLR) do if the source is external? Has this behavior changed with recent firmware updates? My goal is to use DSP (REW-based correction) consistently for both music and TV audio, so I’m trying to understand if the A6 can function as a central DSP hub or not. Any real-world experience or confirmation would be greatly appreciated. Thanks!
In my experience, PEQ was not able to be used for ARC input on my DMP-A6 Gen 2. It is almost certainly the same problem for the other digital inputs. Basically speaking, if it cannot be played back out through a digital output, then DSP cannot be applied. Those digital inputs can only be output through the internal DAC/analog lines out, and unable to be processed and passed through to a digital output. Whatever prevents them from going back out a digital output also prevents them from having DSP applied. -Ed
thanks Ed seems my wiim is best value... The eversolo DMP A8 does let you EQ inputs but thats a whopping 2000 euro... So to EQ netflix the A6 is useless so for 1200 euro extra i can lol
Hi absolutely correct excellent reply or post. However, I am certainly aware this may not be possible or even needed for some folks. But I really do believe the A8 is somewhat of a better unit only speaking in personal opinion, of course, One of my main personal reasons being, I had really anticipated and wanted to use of the AKM 4499exeq, as I already retained a few ESS Based DACs, I have a buddy with an A6 Masters edition I believe I’m correcting name? he could’ve easily went with an A8, but personal opinion, he prefers the A6 however, they’re both very good units and their overall performance sonically speaking, Naturally again it’s all dependent upon ones personal preferences and needs, or desires ect ,Please correct me if I’m wrong I don’t believe the A8 Is way out of line in cost ratio in terms over the A6 gen 2, again for a good number of users that absolutely fits their criteria in overall need, Naturally, you can find what you seek in somewhat of a lower cost ratio as I believe someone had mentioned a competing unit, however, I have no actual knowledge other than what you folks comment on as per other unit s information and user abilities , I certainly may be wrong. Just my opinion, I’m very content that I waited. And went with the A8 , also numerous other reasons, specifically speaking, also my cost was no where near 2 g’s , however I think you may be referring to euros, I believe, in which I’m sorry about that, seriously considering with all due respect, ln opinion only I absolutely believe it may be certainly worth it , to some. please have a great week. Everyone enjoy
DMP-A8 includes a full-on, active buffer preamp with remote relay-controlled resistor ladder volume attenuator. A similar stand-alone preamp would cost as least a few hundred dollars (for example Topping models L70, A70 Pro, or Pre90, or Schiit Saga 2 or Kara F). -Ed
Yes sir you are absolutely correct in your assessment,Unfortunately a few Thousand for a really great , R TO R, or a TVC , based units, naturally it all depends on what satisfies your needs or wants ,Also depending on affordability and what it may be worth an actual use personally, speaking all in decision of the user, example I have spoke and met with a few folks where in their personal opinions, were Eversolos were overly complicated, and preferred something somewhat simpler in overall operation, And I have also spoke with folks that are complete opposite. Lol A good example or I certainly believe so, I have acquired. a friends Eversolo Z8, I have been in complete comparison of much more costly units, of the same, as of this present time, I am completely happy and even somewhat overwhelmed of the overall performance of this particular unit, personally, speaking it absolutely depends how far you may want to go, But in total evaluation, it is most likely not cost prohibited or worth it in the end, However, again, I certainly do not associate this within every audio device naturally,
I fully understand the sentiment of too much complication. My own current chain is: Roon -> Raspberry Pi 3B with RoPieee -> Topping D90 III Sabre -> Topping Pre90 -> Topping B200 monobloc amps -> MoFi SourcePoint 8 standmount loudspeakers And an SVS SB-3000 subwoofer attached to the RCA output of the preamp (the monoblocs to the XLR output) low-pass filtered at 30Hz. Each role has its own component, but each component has only one job. -Ed
Hi that sounds like a very nice setup, and a extremely useful and sensible solution, Unfortunately I cannot even begin to describe or give total use in terms of listing All equipment in a specific or descriptive manner or nature , just off the top of my head , for lack of any on going terminology, I would estimate approximately, in terms of over all visible view, at minimum 20, over all audio devices, including 2 turntables, and reel to reels, yes I would absolutely agree, a bit much for some folks, now some devices are 15/20 years in a age, Re/ 4 tube amps , 2 SS crown amps driving 2, 18’in jbl subs. Throughout the years it happens I would imagine, lol Room size, approximately. 18 X 24X8’ in overal size or dimensions, I wish it were just a little bit bigger and overall dimension, oh well it is what it is and thank goodness I have that , wright ?however your system sounds very intelligently laid out from what I can view. It would appear to me. You would have very good synergy sonically speaking with the system in its entirety, yes you’re never done even though I have state such probably hundreds of times, oh well lol * Yes Ed , sorry I’m just somewhat curious were crossover points or settings on your main or stand mount loudspeaker , and at what db per oct, this maybe be pre Ordained in some specific setups Today , I don’t really know, as I have to manually adjust or change Xovers points , example 80/ 100 Xovers at 18 db per oct on sub only use to be somewhat common, just wondering , however Not important, but thanks either way , have a good day… *ADD ON/ Hi Ed, sorry I didn’t believe I would be able to still find a pic of the subwoofer, You seriously have me reminiscing I wish I would’ve kept it. You absolutely don’t see them around that much today. What a beautiful subwoofer he ran an operated everything with his daughter, and also sold one moving coil Phono cartridge, which I believe was a Van Den Hul build. Again I do certainly apologize for the add-on ,at this time . Respectfully,
I've experimented with all sorts of different crossover configurations from 80Hz full cross at 24dB/octave high pass plus 12dB/octave low pass to 40Hz full cross at 24dB/octave both ways and finally recently discovered that I got my best results by playing the speakers full-range and just having the sub play with a 24dB/octave low-pass filter. My standmounts have an F3 of 37Hz, F6 of 33Hz, and F10 of 31Hz with boundary reinforcement, which is pretty remarkable for non-floor-standers, but then again Andrew Jones is an absolute genius, isn't he? -Ed
Hi Ed, yes, Andrew Jones absolutely I would definitely say he has his act together, Please correct me yet cause I’ll probably be incorrect. I own a very small and inexpensive pair Please don’t quote me LS 22 I believe . A small two way black ash. The speaker is somewhat rounded towards the back, I was totally amazed at the sound they produce when using them as a small monitor at my computer/ Workstation, etc. which serves multiple purposes as a matter of fact, I don’t remember, but I actually have two pairs and I don’t remember how I acquired the second pair but they’re pretty amazing little SPEAKERS. I think they were around $200 or less for the pair if memory serves me well yes, I agree with you. 100% on that, however, yes, I have performed using my main speakers at that time which were pro ac, Studio ones, Which in a roundabout way are still being produced, but their appearance is somewhat different and naturally have a new name, but it’s basically the old studio one, What worked out wonderful at times, especially sonically speaking in the mid range naturally, including other frequencies from approx 100 Hz out of them really brought the monitor to life as naturally the dedicated amp that was powering them did not have to produce these frequencies on down, I do remember running them full range. You probably won’t remember most folks don’t using a Janice W1 subwoofer with his A1 in inter face crossover. AMPLIFIER, Yes, the manufacturer John Marcovis , unfortunately has been gone for quite some time, but what I liked about the specialty guys or manufacturers was that all that’s all he produced was the big subwoofer which I had owned in a model called the A3, which was the smaller model. Very nice. A very articulate base you didn’t even know it was active unless it was called upon house in a big, beautiful custom-made oak cabinet, A little bit of reminiscing, but it seems like all the old good stuff is gone, but there’s much improvement out there today, interest in 24 hz The old timers used to call that frequency hitting a brick wall, but it does work in specific applications, well, it certainly sounds like things are working out for yourself. I’m very happy to hear that. Excellent best of luck. Let me end here before I ramble on but thanks for your reply. Please have a good week, lol
I'm currently adjusting parameters not in the A6, but using an external Luxin X8 DAC. It allows me to easily create and apply the desired parameters to the DAC using AI (Deep Seek) prompts, which are quite adequate. The AI provides a detailed report on parameter profile creation. You can take into account the DAC input and output types, for example, creating a profile for the tube version of the top-end DCS Vivaldi APEX DAC tailored to your needs, and all this is easy. I'll share an idea related to this for the A6. If I create a prompt in Deep Seek based on the A6's parametric equalizer conditions for creating a desired parameter profile and specifying the conditions, perhaps you'll get the desired set of parameters that can be transferred to the A6's equalizer parameters? I haven't tried it, but I'm willing to give it a try...
Does the AI know somehow how your system / room responds...? without that kind of input I doubt you can achieve something "usable"; using EQ to correct / enhance your system applies only to your system in your room; it is not a one-fits-all kind of thing.
Of course he does, and he suggests and explains how to use a calibration microphone and which brand to use. Once I find a suitable microphone, I'll do the calibration—that's the basics. Meanwhile, I'm creating profiles of the world's most expensive DACs, tailored to my X8, including the type of outputs and inputs, as well as the brand of my equipment and speakers, and refining their parameters. Believe me, this is a whole new level of audio processing, and one that's perfectly suited to your needs. The more precise the prompt, the better the result. What requires experience with equalization parameters on the A6 is easily and simply achieved on the X8.
This somehow makes no sense: 1. until you do room calibration with "such" microphone, there is no need to do any profiling for any device. 2. "most expensive DACs" means nothing, unless you DO own them, and made a room-profile with the mike mentioned above. Playing around and familiarising with settings and what not is somehow useful, though. But only to the extent that you may find yourself more comfortable when need to manually adjust the parameters arises.
That's the most important thing! But everything matters for a music lover who isn't chasing microphone accuracy, but solely the sound that suits them in the listening room. By the way, a DAC with AI is like another dimension in the possibilities and experiments of achieving different sounds. It's a very interesting endeavor. An equalization curve that's often very close to a straight line significantly changes the space and the perception, it's like having many different DACs and turning them on one after the other.
