Any updates or info to share?

This looks very interesting. I like the original TTVJ Slim.


So the big question is... which DAC chip does it use? For example, does it share a name with a Buffalo hockey team?  biggrin.gif

This week is the last week for the Glacier to be on sale! We will be shipping either right before RMAF or right after. PLEASE place your orders at our website to reserve your Glacier. The wait will not be long! And of course you have our 30 day money back guarantee to insure you are fully satisfied with the Glacier.

Here is more info on the Glacier...



  • 24-bit, 96-kBPS USB DAC – A Cirrus Logic DAC driven by a Tenor isochronous USB interface provides support for up to 24-bit, 96-kSPS digital audio from a USB host.  This implementation requires no drivers, and works seamlessly with Windows or Mac PCs or other devices with a USB host port (including the iPad using the Apple CCK).  Charging from the USB DAC port can be enabled or disabled, to allow use with low-power portable devices that cannot supply enough current to charge the Glacier.
  • Stepped Attenuator - No cheap volume control pot here.  Small potentiometers are notoriously bad - they mis-track, get noisy, and break.  So the Glacier uses a microprocessor-controlled analog stepped attenuator.  Each of the 32 steps changes the volume level by a precise 2dB, and the gain difference between channels is less than ±0.2dB - compare that to normal pots that at best provide ±3dB!  The current volume setting is indicated by the color of the front-panel LED. In addition, you can select 0dB, 10dB, or 20dB of maximum gain at the press of a button, to accommodate all sources and headphone sensitivities.
  • High output power - What's the point of a headphone amp if it can't drive any more than your iPod?  Using a current feedback amplifier, the Glacier puts out 2.6V RMS (7.4V P-P) and up to 100mA of output current, so can easily drive nearly any headphones.  The highly efficient, high frequency regulated power supply guarantees full output power over the life of the battery, with low noise and high output current for powerful bass response, even with low impedance headphones.
  • DC-coupled design - The signal path in most portable amps is AC-coupled, with a single power supply.  This requires the audio signal to pass through multiple capacitors, which degrade the sound and limit frequency response.  The Apex Glacier has a bipolar power supply, allowing the audio path to be DC-coupled.  That means the low-frequency response extends to 0Hz!
  • Long-lasting, rechargeable battery - The Glacier contains a lithium-polymer battery which will power the amp for 12-15 hours at typical listening levels.  It recharges in about 2 hours from any USB port, or a USB wall charger.  You can also operate it while plugged in to keep the battery topped off.
  • Slim, stainless-steel case – A full metal enclosure with stainless-steel skins makes the Glacier slim, strong, and resistant to EMI (electromagnetic interference).  Sized to match common portable devices, the Glacier is the thinnest portable headphone amp made!



  • Frequency response: DC to >100kHz, ±1dB; 20Hz - 20kHz ±0.1dB @ 1V out
  • Maximum output: >2.6V RMS into 150Ω; >1.7V RMS into 32Ω
  • Output source impedance:  Approximately 2Ω
  • THD+N: 0.005% @ 1V RMS out, 20Hz - 20kHz into 150Ω
  • Broadband noise:  <10μV RMS, unweighted, integrated over 20Hz - 20kHz
  • Output DC offset: <5mV
  • Input impedance: 10kΩ
  • Maximum input level: 2V RMS
  • Channel tracking (gain difference between channels, all volume steps): <±0.2dB
  • Maximum gain:  0dB, 10dB, or 20dB, ±<0.5dB
  • Dimensions: 114mm long x 65mm wide x 9mm thick

Doesn't seem to be having any Output source impedance and Maximum gain output ratings differences compared to your previous TTVJ Slim portable amp product, that you have seemingly discontinued it recently since I did not see it being listed anymore on your store website. Look's like I'm still good and not losing out much here.

Todd it's certainly good to know and you are doing the community here a huge favour, by updating all the bells and whistles about your newest products, but I think I would appreciate even further as part of the community if you could just kindly take some of your time to reply your mail inbox or Head-fi PM inbox. I have been trying to reach you with 2 emails, 2 PM msgs but with absolutely no response from you. Needless to say as your new customer, I'm not very amused by your standards of customer support. It's been more than a week now ever since I sent you my initial email, and I'm not even expecting a 24-hour or 48-hour turnaround timing in regards to email replies, as I do understand everyone can be busy in our daily lives as well.

Please kindly get back to me soon, you know how to reach me.
