Video

5 DD, 5 BA or mixed, 5 in total?

If I ever listen to the other 4 I'll definitely let you know for sure ;)

Exactly how I planned it 🤯 .... Ok, but seriously ... Is it just this video, or also my more recent videos? I did modify some recording techniques recently that I hoped would make the audio more clean, but I only test the sound on headphones at home.

Unfortunately it's the earbuds. I can hear a small imbalance, and both buds were measured on the same side of the miniDSP, with a DIY foam mount (at 5:34) that I made to make earbud measurements easier and far more reliable than the silicone ones supplied with the EARS. With that piece of foam I get insane consistency, and more accurate graphs compared to the EARS.

I'm surprisingly not very interested in that... I know... sacrilege.. Once upon a time, I tried powering my HE-500 with an Emotiva a100, and heard no obvious difference between that and under-powering it with an O2 amp ¯\_(ツ)_/¯ Of course, now I do better understand the reasoning behind providing endless headroom, it's just not something I've needed with the audio-gd NFB11.28 TXCO lying around with its 3.5W @ 32 ohms... Also, I'm not exactly comfortable with the potential risks involved. I can only see it being useful for a very select number of headphones, and even then I'm not willing to take those risks for a demonstration. That said, I don't think I even have all the physical cable adapters and the electronics knowledge required to make a decent video :P

@@GREQReviews Thanks for the explanation. Just keep going with your awesome videos and I'm happy :)

Yeah, I think that's actually quite a big deal. I was very impressed with the LCP driver in the MDR-1R

Yes, the PH05 will definitely be able to run it at and beyond normal listening volumes.

I assume you want to bypass the DAC portion of the K5 Pro? Depending on what you want your audio source to be, you could use an HDMI to COAX adapter... but that's already getting weird. Any particular reason you don't want to power it with USB and use the DAC?

I'd like to try some of those out one day, especially the A8.

Yeah I can use iems and tws, but flatheads are a nightmare for me lol.

Thanks for helping the algorithm :P

I'm afriad not. Let me know if you ever find a good one 😅

That is correct - the unit WILL turn on, and it WILL remember the last input selection :) (I'm glad someone enjoys my awful sense of humour)

Did you ever tried Audio Technica ATH-2 ? If yes how do you compare with TDS-16 ?

​@@yanturcotte7377 Keeping in mind that I havn't heard a Sansui SS-100 or a Yamaha YH-1000 (and a few other unicorns) my top pick easily goes to the Yamah HP-1. It just sounds REALLY good out of the box. Maybe for 2nd and 3rd a Fostex T30 and Fostex T20RP (original version with round driver) or one of it's OEMs. T30's are very capable too, but could use tone correction. They're smoother sounding than HP1. T20RPs are very closed-in, dry and VERY clean sounding, but need different over-ear ear pads to sound their best... so I guess that's a mod (although most of them today need new pads anyway). I have heard the ATH-2, and MANY other variants with the same driver - they are usually the worst vintage planars around.

Thank you for your answer. What is the difference beetween de HP-1 and YH-1 ? So you think Fostex T30 is better then T50 ?

​@@yanturcotte7377 YH = Export (generally speaking) HP = Japanese/domestic. The only difference is the printed letters :) I think T50 (RP18) driver is better than the T30 driver, but SERIOUS mods are required to get them sounding their best (as seen in my NAD RP18 video). The T50/RP18 housing adds a 'boxy' timbre. So I think a stock T30 + tone correction sounds better than a stock T50/RP18 + tone correction.

Thank you for the explanation. I just bought on ebay ( not received yet ) a New old stock TDS-16 following your review on it. You mention it as a YH-1 like driver. What do you think the difference between them and Hp-1/Yh-1 ? Will it be redundant to have both ?

Sorry, there are so many versions of the DT770, could you be more specific? (My version is Pro 80 ohm which is still 'modern')

@@GREQReviews The most distinctive change I know from the old models to the new one is the logo The old (in three versions 32, 80, 250) has this logo ))) The new one has a "y" instead of the ")))"

@@husamalden2897 No idea. I've never heard the new one with the 'Y' logo. But realistically the new version should only be a cosmetic update. The sound should be very similar, or the same, since they have an invested interest in maintaining a consistent level of quality in their studio line. If there were any big changes I think we would have noticed an uproar by now.

I recently noticed that switching to foam tips for the HBB PR2 makes a HUGE difference to reducing the piercing treble. I can't recommend using foam tips enough. This is something I will definitely watch out for in future IEM reviews, since tip-rolling is of course so much more common than ear pad rolling.

Something tells me you might not be too far off, because I could detect no obvious reason why anyone would take the open-back over the closed-back versions aside from price, or requiring less isolation.

I'm afraid I don't know exactly which ear pads they are, as they arrived with the headphone when I got it. If you search for aftermarket ear pads (on aliexpress for example) I'm sure you'll find some very similar pads.

Thank you ! I never mod pads, do you know what i have to look for, when buying pads ? Only diameter ? And the diameter of what parts ? Thank you

Actually, the MX10-B, MX-100-Z and MX-100V are all tuned differently! It looks like the 100V is the most 'mid-centric' of the three, but that's only based on some obscure reviews and a single FR graph that I could find.

Hi there, Perun is very different to the RR1. RR1 overall has a very smooth presentation, very much most STAX headphones. It has smaller staging than all lambdas and the high-end circular driver models, but it's never piercing in the treble. It just sounds like a 'normal' headphone (think Senn HD600) but with electrostatic technicalities and a touch darker tuning. Perun is more like a really well tuned and scaled-up SR-Lambda NB, with no significant peaks or dips, but BIGGER staging - these sound HUGE. From the technical and subjective performance, I think they were among the top 3 headphones I heard all day, including the SR-9000X and ES Lab ES1 (which was the one beside the Perun). The extra physical height of these Peruns gives them one of the tallest soundstages I've ever heard. It gives an incredible sense of scale to the sound. Maybe not the biggest soundstage ever, but still really quite big. The tone was VERY impressive for an e-stat - riding the line between analytical and euphoric. The ES Lab ES1 was warmer.

The Pre-Out is a full-range output and can be used with any 2.1 speaker system or anything with an amplifier.

Happy to hear you're enjoying them. JVC's best stuff is far too obscure.

@@GREQReviews Oh I know. Had HA-S500, S680 and SZ2000 in the past. Too bad they're all gone, the carbon nanotube tech was pretty special.

@@timecage Your comment belies the biggest problem with JVC - build quality.

@@GREQReviews Well the SZ2000 weren't built very well considering the weight of the drivers and their chambers. But what I mean is that they're no longer being sold. Never had any quality issues other than with the 2000s.

Sorry, I don't understand the question. The K5 Pro is a USB DAC/amp.

As I mentioned in the review, I wasn't convinced by it's ability to drive my Hifiman HE-500. Generally, I don't think it's quite strong enough for any large planar headphone. However, my KZ HBB PR2 is driven VERY well by the K5 Pro. I get to a good strong listening level at around 10 o'clock with brickwalled music, and have plenty of headroom left for properly recorded music around 12 o'clock. The bass boost with PR2 is quite good too ;)

I do. With the sub at FULL volume, it is still nowhere near as loud as it should be to be balanced with the sound from my speakers. It's a matching set of Yamaha NS-615B + Yamaha NS-W1.

Every single product I've reviewed from them had at least one quirk or oddity. SK01 seems like the most 'normal' ... until you realize it has a BATTERY inside making it somehow portable!??

Fosi is emerging as the king of "Almost"... czcams.com/video/ox-NkyEFTmo/video.htmlsi=P8DX88eU3hjq6ort Like most of these mini-amp makers I seriously doubt they're sitting down and planning systems or analysing use-cases. It's more like "Hey I've got an idea" but never thinking it through to how useful it will be. This MC351 will likely find a home with people wanting better than average TV sound, repurposing a third speaker as a sub-woofer. But that's about the only niche it will fill.

This is definitely the first time I've had a Fosi product that I don't really understand.

Did you add a high pass filter to your sub?

​@@GREQReviews Do you mean lowpass? A sub with a highpassed signal puts out no subbass... 😂

@@ropeburn6684 Lol yes... typo/brainfart 🥴

Yeah seriously. If you have a subwoofer, what's the point with running main speakers full range? They will just be stressed with subbass which they can't reproduce anyway.

Good point. The MC351 assumes the sub has it's own high pass filter.

Just buy bass blockers they are cheap and put them directly on the positive terminals on the amp then run your wire from it to your positive side of your speaker terminals. I have a 150hz bass block on mine now the bookshelves are playing nothing below 150hz however I left the sub unfiltered and is the only thing left playing low.

​​@@GREQReviews Usually they do, yes. But active ones, on line level. How are you gonna loop the filtered signal back to the main amp? You'd need tape loop functionality or something, or else you'll need to use a separate preamplifier for source switching, negating the whole point of an integrated amp. All this nonsense could be avoided by having a simple highpass for the main channels. And ideally a matching lowpass for the sub out.

Thanks! Also good to know I'm not the only one griping at the mixed bag of features.

@@GREQReviews we are in the same boat!!!!

@@GREQReviews wow quick and sharp response, impressive !

@@AlbertEindeux345six Immediately leaves for 1 and a half hours....

Do you have any specific pads you would recommend?

@@GREQReviews Yaxi Alcantara earpads for th900 (choose either leather or Alcantara, different sound) works for 909 and 808 as well Also, you can use the Dekoni elite hybrid or leather. (Don’t have them) also works on the open back version. Right now I’m using some unknown leather earpads the importer bought and modified. Sounds good to me. Even he said he hates the stock earpads and the long cable. Same goes for almost all of fostex headphones
