BNIB: LH Labs Geek Pulse DAC & Headphone Amp
« on: February 04, 2017, 06:02:12 PM »
If you're looking, and know about LH Labs; then you already know...what a little gem this is. For those of you, who may be thinking "who the hell...is LH Labs"? Well...the LH, is for Light Harmonic. Still lost?

Oh...they make DACs, that cost like as much as your car (the > $30k DaVinci http://lightharmonic.com/products/da-vinci-dac-mkii/ )...or maybe your house (the forthcoming > $120,000 Sire)

LH Labs...is the spin-off offspring; for us poor working slobs...on a budget, lol. Can you say trickle-down? http://marketplace.lhlabs.com/products/pulse-dac-headphone-amplifier

I tried a used one; both as dedicated DAC...in a 2nd system, and as dedicated, standalone headphone amp. Great little box; I liked it so much, I bought a brand new one! But I disbanded the 2nd system, and never found a use for the sealed one...as I am trying to downsize now.

Usual, usual; buyer pays s&h...and PayPal fees if needed (F&F is an option...but only if you have good and recent feedback). Speaking of feedback; check mine out, and buy with confidence.

Specs

USB Audio Class 2.0 input with other 4 digital audio inputs all converted to 3L buffered I2S signal, then send to DAC IC

Full balanced current output then transconductance amp then summing up output amplifier

Two audiophile grade low jitter TCXO with super quiet power circuit and mu-metal shield

DAC IC: ESS9018K2M

Digital Inputs:
One USB 2.0 Type B Female
One set SPDIF via TOSLINK (JIS F05 Female)
One set AES/EBU (AES/EBU input compatible SPDIF signal by Adapter)
Two set SPDIF via RCA Coaxial

Supported Native PCM format: 44.1, 48, 88.2, 96, 176.4, 192, 352.8K, 384 kHz in 16/24/32 bit

Supported Native DSD format: 2.822, 3.072, 5.644, 6.144 Mega Hz / 1bit (via USB 2.0 Input) Support both DoP standard 1.1 and Native DSD (requires ASIO driver)

Patent Pending: 3L buffer by Light Harmonic Dual loop re-clock for all digital audio inputs

Single-ended output voltage and impedance: 2.1Vrms (47 Ohm)
Headphone output configuration: Single-end via 1/4" TRS Headphone Jack
HP Single- ended output voltage and impedance: 1.8V / 3V / 6.8V switchable (0.47Ohm flat in 20~20K Hz range)

THD+N: Better than 0.005%
SNR: Better than 110dB
Frequency Response: 1-50K (-3dB) control by Bessel analog filter
Power Input: 12V DC - 650mA ~ 950mA depend on system load and sampling rate

Email with any questions; a true audiophile, never minds talking a little shop...lol.
