I have a TTVJ Slim and am quite happy with it but the amount of tech they managed to stuff in the portaphile is quite amazing not to mention the opamps themselves. Anyway haven't been able to find a review and it's quite a leap of faith for 550 plus shipping, thought you might be able to shed some light on it for me.
That question is not derailing (although it could have been asked in my amp thread ) this thread as I think the entire chain is important. Yes, I have it and am currently working on the 627 review and hope to have it complete mid next week. A quick summary is this...if you notice a difference with the TTVJ Slim, chances are you will notice a bigger improvement with the 627. But, taking a step back, if you are using an iPhone as a source, don't bother. If you use something better (my modded iPod is an example), the 627 takes all of the goodness that is there in the music and makes it better. If there is a 3D space, it is larger with better imaging and resolution (from better control of the drivers is my guess). Bass is extremely powerful but so very well controlled. The whole presentation is clean and smooth from top to bottom, and it is the only portable that can make my LCD-2 sound good! For high performing CIEMs, it adds an extra level of realism when combined with at least a good DAC. It isn't perfect though and I will have a more complete write-up in my review.

But I don't know if it's because I listen to too much 5 way recently. I find my JH16 is really bright, really sparkle with lots of sibilance on vocals (especially hip hop vocals).and I can't even recall what it used to sound. lol I understand JH16 has a peak at 6Hz to boost the clarity because of the enhance bass. I wonder whether my JH16 has gone defective. But I don't think there is problems with drivers.
If I push the volume up. It's almost unlistenable on clip+, studio V or ipod if I don't add some eq (but if I cut too much I will lose the clarity and the transparent). On 801 it's better but still with certain amount of sibilance which makes the sound somewhat analytical and thin. I guess it's just because 5 way sound so much different. I wish to make sure before I send it back to JH audio.
There are several things it can be:
- Because you have been listening to the 5-way which has smoother treble with a thicker note in comparison with the JH16. You can get used to the sound of something and it will make
- There JH16 could need a cleaning. I suggest you get something like the Serene Hearing Aid dryer and use it for a cycle and check the results. I have noticed that sound tubes can get a bit of moisture in them, which doesn't naturally evaporate, at least in a reasonable time, so a dryer will get that out. Plus, if you plan on keeping your custom IEMs in top condition, I recommend a dryer (and so does Grzegorz).
- You have a sinus infection.
- The fit including the length of the canal and angle of the sound tubes can cause issues with the treble. The more custom IEMs I receive and the more people I talk with the more this seems to be. There have been JHA customers that have had treble issues and sent them back and ended up either with a different canal length or a JH13, which fixed the issues (and some JH13 users have switched to JH16s).
Let us know what how things progress and what is the real culprit.
