I'm using an Aurender N100. It's not capable of DSP. I did some sweeps and sine tones around 800 Hz and 2500 Hz sound like they are stimulating the tinnitus in my left ear. They sound more natural in my right ear. It makes sense that a matching tone would stimulate the tinnitus, but what's odd...

I recently obtained a 2021 LCD-X from an open box sale and listened. Previously I had a 2011 LCD-2. My first impression of the LCD-X was that it was closed-in compared to my LCD-2, but had better bass. A long time ago I reverse-flexed the headband on my LCD-2 to loosen it up (I can't take the...

Shipped fast, in good condition, and exchanged helpful comments on the sound. Highly recommended!

I'm interested in getting an iFi Zen DAC V2 or V2 Signature. I have an old iDSD Nano (not Black Label) which a very talented technician modified and created a super HQ 5V LPS for, and it's a very high performer. Very musical and good extension/resolution. (Not stellar, but good for the money -...

Powervar ABC1200-11 power conditioner as often used in professional audio/video or medical applications. It contains an isolation transformer and surge suppression and is rated at 1440 watts (120VAC/12AMP) so definitely capable of handling speaker power amps as well as the rest of your system...

@gregorio Thanks for emphasizing seeing a doctor. I'll do that. When I say "the problem could be in my DAC" what I mean is that, because not all equipment triggers the resonance equally, it would be nice to find some equipment that doesn't trigger it yet still sounds good to me. I might need to...

I've got a strange problem which was noticeable in the past, but became really noticeable with a couple of DACs I tried recently (a Gustard x20pro and a Gustard R26). When I listen through headphones, there's a resonance in my left ear around 500 Hz. For example, if I play piano tones from a...

Okay, so I've been listening with a NOS "Radiotechnique" French military 12AU7, cryo'd, I got from Upscale Audio. It has a softer treble. Maybe even a little brighter than the Clear Top, but smoother and without that sense of peakiness. By the way, it's not that the LCD-2 is "bright", but...

I thought of one other possible factor.. I use RCA Clear Top 12AU7's in both of my headphone amps. I dropped another brand in there and the tonal balance changed a lot. I'll look into it.

I hear it with an iFi Zen Stream as well. And I've tried several configurations of a NUC driving the Gustard DAC. The general pattern is that whenever my USB transport improves in quality, I get more extension and life in the treble, and that extra treble energy seems to have some peakiness to...

I just upgraded my Win 11/Foobar2000 computer to a dedicated streamer/server, an Aurender N100. I'm finding that I might like to EQ some files for use with my headphones (I have many headphones). But an Aurender has no playback options at all, and I don't see a way to EQ things. In fact, the...

I have an LCD-2 and a custom made cable that dates back to 2011 or 2012. I don't think it was V1. There had been some significant revisions to brighten the sound, but it was pre-fazor. I've recently upgraded my streamer to an Aurender N100. Was previously using a Windows 11 NUC running...

I figured the ZS would need some burn-in time. It's been playing for somewhere between 50 and 100 hours now. When I first set it up, driving a custom modified Gustard X20dac via USB, the transients were a bit aggressive and monotonous (i.e. string attacks had a similar quality to brass which had...

I think the Zen crashed. I was playing music from a folder (on the attached USB drive) that had a bunch of wave files, and then a CUE file that originally came with a large FLAC. I had already split the FLAC into separate tracks and deleted it, leaving the CUE file behind by mistake. I set up...

I got the Zen Stream running with JRiver on my MacBook in both senses: #1 JRiver is the player and it chooses the Zen to direct the signal to, #2 The Zen WUI is the player and it connects to my MacBook as a Media Server. I can also plug a USB drive into the Zen and use the WUI to navigate its...
