You had questions. I have answers. Analog to Digital? Room correction on an analog line in? Yes!

[@OldGuyHifi]

A much deeper dive on the WiiM Pro's room correction software. The unit will digitize an analog input, apply room correction and output on: 1) On the units analog line output. 2) On the units SPDIF Coax output and, 3) On the units SPDIF Toslink output.

@@ramondelgado6778 Which DAC sounds better in You opinion? The SMSL or the Schiit ?

[@ramondelgado6778]

@@lumberjaxx3335 the correct answer is that they both sound different. The Modi 3E is brighter and more detailed, more airy with boomy heavy bass, with the mid range less forward and a bit thin. Most ears will like this one especially if you have extra warm, dark speakers. The SU-1, to me, is more refined, smooth, tighter bass, warm forward mid, smoother highs. My ears preferred the SU-1.

Hey Ed. Here is a reason to get the pro plus over the pro. Line in analog goes in at higher resolution on the pro plus than on the pro. Besides the dac this is one of the main differences between pro and pro plus models

I am going to take the HDMI output of my Apple TV 4K via optical out from my LG TV into the WiiM Pro, then transfer the output to my PARASOUND Pre 200 via optical then send that output to my YAMAHA AS701 integrated amp. via analog out. All this to get Room Correction and EQ. Only paid $130 tax included during Amazon Prime sale! Needless to say I am very appreciative of your video reviews.

[@OldGuyHifi]

Thank you Jack. Please let me know how that works out. Thanks for tuning in and sharing your configuration.

[@JackAldrich]

@@OldGuyHifi First Impressions: remarkably easy to install application. It took numerous attempts to complete the Room Correction process, but once done works great. Just need to pay attention to those input & output settings. All of my config's equipment is new including my B&W 606s on stands. After getting everything connected with quality cables, the music output and especially watching F1 was nice but underwhelming. After I completed the Room Correction process, I started using the EQ presets and the "Movie" preset fixed the F1 playback issue (too harsh, thin sound) Now the F1 races have the robust detailed sound I expected to hear! I have tried a couple of the other genre -specific EQ presets and all I can say is "WOW!" Music sounds correct at last! Articulation and warmth are terms I had only read about now I can hear the music clearly and with real quality playback. I'm not an audiophile or vintage collector but your excellent video provided clarity and led me to purchase the WiiM Pro. Best $130 I've spent in a long time. Now I just need time to re-listen to all my favorites and hear them like they were intended to be heard. Thanks again!

[@Madmart54]

Some one may have already commented upon this and I may be wrong but looking up the frequency response for an IPhone 16 it starts falling away below 100Hz-which is why I think my sweep showed huge lifts required at the bottom end. Also I hope those who are not familiar with the WiiM Pro Plus realise that a mobile phone pad etc.device is being used in the seating position as a microphone and the analogue source is just for demonstrating final connection and plays no part in the room analysis. Also the suggested fr correction can be applied/checked and saved.

Hello oldguyhifi!!! one thing I'm a little confused about is will I be able to get the benefits of the wiim EQ and room correction with the Cambridge AXR 100? if so what input would I plug the wiim into on the AXR100? Thanks in advance and once again great video!!!

[@OldGuyHifi]

Great question. You will absolutely get the benefit. I would recommend plugging the WiiM's Toslink optical output into the AXR's optical digital input. All of the sonic magic occurs within the WiiM and it just outputs the equalized signal into your receiver. Does that makes sense? I hope you enjoy the AXR100 as much as I do. Thank you so much for tuning in.

Could the WiimPro (with, maybe, an external DAC) be used in a vintage receiver’s tape loop or in place of main-in/pre-out jumpers? This would be cool as all the vintage gear’s pre-amp functionality would be retained.

[@OldGuyHifi]

I had that question earlier, I am going to try. My thought is no. The way the unit does its I/O selection and the fact it is a source in and of itself, I suspect precludes it from that type of operation. But, since you asked, I now have something to do tomorrow. I will report back. Thanks Steve.

[@SteveWille]

@@OldGuyHifi Hmmm… I have a WiimPro but no suitable vintage receiver or amp, or I’d try it myself. Before using Audirvāna made it obsolete, I did the following and it worked: WiimPro → Bifröst DAC → Amp, so there may be a chance. I didn’t, however, try using the WiimPro analog in.

[@scootergants]

I'm curious to get your take on the "sound" after running room correction -- I've been using ROON DSP and it's been love and hate :)

[@OldGuyHifi]

If you look closely at the curve, the yellow target line and the purple EQ line were almost on top of each other in the B&K curve setting. I am fortunate that my room has some acoustic treatment and was purpose built as a sound room. The amount of EQ applied didn't really do much for me. Also, truthfully, I am not a DSP or digital EQ fan. I have a Schiit Lokius that I use to apply tiny amounts of EQ when needed. Since I really don't have any bass issues in my room, which is where most rooms have problems, it did nothing much. I can see its value in untreated or problematic room situations. I do think it can help many people achieve better sound so it is a good unit for that. I understand your love-hate relationship with Roon DSP. Thanks so much for commenting and for watching. I do appreciate it.

[@PaoloPunsalan]

You can also save the current room correction EQ (named as "Auto" on EQ list) when you click "Save" and select "+ New Custom EQ" and enter your preferred EQ name. This way, you don't lose the settings when you decide to do room correction EQ again with different settings.

[@OldGuyHifi]

Paolo, That's great info. I did not know that. Thank you.

[@DethFromAbove1985]

Thanks Ed. A lot of great info!!! One stupid question! If one did the following.... Turntable>>WIIM>>DAC>>Integrated Amp With a built in phono stage in the integrated would it be okay to run the ground from the turntable to the integrated and rca to the wiim? Or would you have to stick a separate phono stage in there?? I'm a little bit of a Newbie.

[@OldGuyHifi]

you would need the separate phono stage as the the WiiM and the amp are not on the same ground plane.

How does the room correction sound compared to no RC

[@OldGuyHifi]

Leo, Great question. Truthfully I didn't care for the results. If you saw the amount of correction it wanted to apply, it was small , as my room is treated already. The EQ the unit applied, to my ear muddied the sound to much. The room correction theme was more of a proof of concept/informational video for folks curious about how it works and how you set it up. Many people are interested in room correction and no other reviewer did a deep dive it how it functions. It can help many folks how have little control over where their Hifi is located so it could be a big benefit to them especially with low frequencies. . In my case not so much. Thanks so much for you view.

Hi from another old guy that enjoys your channel and what you do. Thanks for that. I'm scratching my giant bald spot though.. I use TIDAL for everything now. I don't intend to ever go back to analog for anything. I'll let my DAC do that. Listening to these channels though, as I understand it, a person would use a turntable or tape because it starts analog and it stays analog all the way to the speakers. My question then is, why bother owning anything analog if you are going to convert it to digital? I think that the equipment owned by the TIDAL's of the world would do a much better job of conversion than a personal streamer. Doesn't matter to me though, I only stream. I just wanted to comment and see what you think. Thanks.

[@OldGuyHifi]

Maurice, You do make a good point. In the world of vintage, the idea of being able to play back all those old records and tapes has a huge appeal. I listen to vinyl all the time myself and no I would not necessarily want to digitize that signal for any reason. However, being able to do the room correction on any signal, analog or digital, can make a system sound more balanced as it can correct of some minor room anomalies. I am lucky in that I have a partially treated room so, my issues are minor at best. I do use an EQ just to fine tune the sound to my tastes. My feeling is that if it helps someone enjoy their music more that is great and ultimately all that matters. Thank you for the great question/observation.

[@michaeldina1103]

@@OldGuyHifiWell said! Yeah I think for most of us audiophiles we are going to optimize our room and/or equipment first before resorting to ADAC to be able to room correct for analog sources.
