About Me:

Just another guy who enjoys listening...

What I do for a living:

Spend money I find under rocks

Headphone Inventory

OPPO PM-1
(A freebie from OPPO, following four months of Beta testing - so I'm biased, but here's my mini-review: http://tinyurl.com/mynenrk and some pictures: http://tinyurl.com/m3x9yal PM-2 Pads make it better still.)

Sennhesier HD800
(Too bright and revealing of faults in upstream components. The Metrum Acoustics Octave MkII NOS DAC made a huge push in the right direction and the low-feedback, single-ended, Class A NuForce HA-200 brought me almost to perfection with the HD800, but now I am awaiting the Metrum Acoustics Aurix, a zero-feedback amp that matches the Octave MkII - this might be my "final solution" for the finicky HD800.)

Sennheiser Amperior (Silver)
(Lower build quality than the Beyer DT1350, but more comfortable and amazing sound - a poor man's LCD-2!)

Audez'e LCD-2 rev.1
(Almost everything I want in a headphone - yes, I slightly prefer it over the OPPO PM-1 - if I had to get by with just one headphone. If only I could find a way to give it a 13-Watt into 50-Ohm, neutral and transparent signal.)

Audio Technica ATH-M50
(Best $100 headphone out there - but it only sounds like a $150.)

Sennheiser HD280
(A sleeper - bang for the buck)

Shure E4g
(I'm not into IEMs, so these will do...)


GONE BYE-BYE...

Sennheiser HD600
(Sold - Considerable bang for the buck - especially on the Beresford Bushmaster MkII.)

Sennheiser HD650
(Sold - Surely, the offspring of an HD800 and LCD-2, the HD650 was the best compromise out there, until the PM-2!)

AKG K550
(Sold - My head wasn't wide enough for a good seal.)

Philips CitiScape Downtown
(Gifted to 91-year-old friend who loved them for listening to dixieland jazz - now deceased...)

Shure SE530
(Sold - awesome IEM, but seldom used)

Beyerdyanmic DT1350
(Gifted to a friend - sounded great, but I've decided I don't like the discomfort of supra-aurals)

Beyerdyanmic DT1350 "Facelift"
(Sold - A comparison with the Sennheiser Amperior ... Amperior wins!)

Beyerdynamic T1
(Sold - I had a love/hate relationship with the T1 due to not having the right amp - for my tastes, the T1 wants a tube amp, but I'm not willing to go there - I'm too obsessive to roll tubes!)

Headphone Amp Inventory

Metrum Acoustics Aurix
(A zero-feedback "transformer-powered" amp, this is a cosmetic match to the Metrum Octave MkII, but promises to be the "final solution" to my HD800 woes. Ordered, awaiting arrival...)

NuForce HA-200
(Purchased as a "solution" for the HD800's bright and brittle treble. Using this amp with my Metrum Octave MkII has finally given me the smooth, yet transparent and very detailed treble I've spent a long time trying to secure for the HD800. This is a LOT of desktop amp for the money - I highly recommend it to anyone wanting to spend $350 or less for a desktop amp. I have not tried it with another HA-200 in balanced mode, as I personally think it's got plenty of power for the HD800 single-ended.)

OPPO HA-1 DAC/Amp
(Had Beta test units for seven months, beginning mid-December 2013 - Received a silver HA-1 of my own in August 2014, for keeps. This DAC/amp does it all - with everything except the finicky HD800, that is...)

TBI Audio Millenia MG3 - with a TBI-made external 10:2 resistor network
(A ridiculously good 32W into 8-Ohm speaker Class BD speaker amp that I use with directly-attached 8-Ohm Def.Tech SM45 near-field monitors or with only very efficient headphones or IEMs via the TBI resistor box and appropriate cables)

CEntrance DACmini CX with 1-Ohm output impedance mod
(This thing does so much, so well. I will never sell it.)

iBasso PB2 Pelican with HiFlight TopKit
(Currently running Frugalphile's LME49990 x4 in L/R + dummy buffers. Portable power!)

Meier Audio Corda Stepdance
(The ultimate portable amp, IMHO - and, believe it or not, this little guy is my absolute benchmark for neutral transparency - seriously - every amp gets compared to the Stepdance when evaluating neutrality and transparency!)



GONE BYE-BYE...

Schiit Valhalla 2
(Returned under Schiit's gracious 15-day trial guarantee, I'll say it was my least fatiguing amp for the HD800 to date, but a little too laid back (10th row seating) for my tastes and a somewhat lacking in dynamics and bass energy, compared to a good SS amp like the OPPO HA-1 - where, I'm back to dealing with HD800's fatiguing treble. HD800: A world of compromise.)

Beresford Bushmaster MkII (TC-7533) DAC/amp
(Sold - Spectacularly non-fatiguing, detailed, transparent, low-noise DAC and intergrated amp, runs on 12VDC, pulling only 60mA, and makes HD600/HD650 and the PM-1 sound their very best. This thing almost sounds like a Speedballed Bottlehead Crack (per a couple of friends), but it's solid state! http://tinyurl.com/ny2oq6g)

Schiit Vali hybrid mini-amp
(Sold - This giant-killer was my favorite solution for the HD800, until it wasn't. Aside from the microphonic ringing, which really wasn't a problem for me, it has a constant sheen of sorts that makes the timbre of every instrument and voice sound similar.)

Emotiva a-100 Mini-X
(Sold - 8 Watts per channel into 50-Ohms - but a little bright and a little harsh, even with LCD-2)

Burson Audio Soloist
(Sold - I liked it with the Beyer T1, but prefer the sound of the LCD-2 with DACmini CX - for real.)

CEntrance DACport
(Gifted - an awesome piece of gear but I didn' t really need it as much as a friend of mind did)

Source Inventory

iPad 3 + Pure i-20 iDevice Dock
(Blu-Tacked to an 8x5-inch slab of grey marble, it's much more stable with the iPad 3 - using Coaxial out to the Metrum Acoustics Octave MkII (and from there to the Metrum Acoustics Aurix and HD800) - primarily for streaming TidalHiFi and Netflix movies - which look great on the 2048 x 1536 Retina display - that's quite large at a viewing distance of only 12 inches. This has put an end to using Bluetooth to get form iDevices to the OPPO HA-1 - which forced use of the HA-1's ESS9018 "glare-inducing" oversampling DAC.)

Metrum Acoustics Octave MkII NOS DAC
(My absolute favorite DAC of all time - which isn't saying much, as I haven't been around the block much, but still...)

FiiO X5 DAP
(Wow! Here are my initial impressions, only three days in: http://tinyurl.com/n8p8apv)

TeraDak Teralink X2 USB-to-IIS or USB-to-S/PDIF Converter
(I was only using my Concero as an S/PDIF converter for the Beresford Bushmaster MkII, until I bought this giant killing, bang-for-the-buck converter which sounds every bit as good. It's limited to 96/24, but hear this - I genuinely consider this affordable, Taiwanese-made product to be superior to the USB receiver in my OPPO HA-1. Seriously - it's a great upgrade to the HA-1's USB input - going in Coaxial, instead.)

CEntrance DACmini CX with 1-Ohm output impedance mod
(The DAC section has just a tiny bit of "etch" in the treble - great with LCD-2 rev.1)

CEntrance DACport LX
(Sold and bought again, after buying the DACmini CX. The LX is a must-have for traveling with a laptop!)

Toshiba Windows 7 laptop + Foobar 2000 + WASAPI plugin > USB

Sony PCM-M10 - 96kHz/24-bit Linear PCM recorder/player
(My favorite portable source for 3.5 years - preferred over HiFiMan HM-801 and TASCAM DR-100, but replaced by the FiiO X5)

Sansa Clip+
(8 GB + 32GB & 64 GB microSD cards)


GONE BYE-BYE...

Beresford Bushmaster MkII (TC-7533) DAC/amp
(Sold - Ridiculously good sound, runs on 12VDC, pulling only 60mA, and makes HD600/HD650 and the PM-1 or PM-2 sound their very best. This thing almost sounds like a Speedballed Bottlehead Crack, but it's solid state! http://tinyurl.com/ny2oq6g)

Resonessence Labs Concero w/Apple Remote
(Sold - Amazing USB power management when external power isn't convenient.)

Decware ZSTAGE Zen Triode Tube Gain Stage
(Sold - with JJ ECC82, PSVANE T Series Mark II 12AU7, NOS Radiotechnique 12AU7, NOS Siemens 12AU7, NOS Mullard 12AT7)

HiFiMan HM-801
(Returned on 30-day trial guarantee for a full refund. Here's why: http://tinyurl.com/mftmfvz )

TASCAM DR-100 MkII - 96kHz/24-bit Linear PCM recorder/player
(Returned after one day of ownership for a refund. Here's why: http://tinyurl.com/mx89gdk )

Stoner Acoustics UD100 ESS9018 USB DAC
(Sold - dry and lacks dynamics, but smoother treble than the Objective DAC)

JDS Labs Objective DAC
(Returned on trial guarantee with 15% restocking fee - intermittently "screechy")

iBasso DB2 Boomslang2 DAC
(Returned on trial guarantee - "lifeless" and too dark - at least for the LCD-2 rev.1)

CEntrance DACport
(Gifted - an awesome piece of gear but I didn' t really need it as much as a friend of mind did)

Cable Inventory

AntiCables
(2x 2m speaker wires and 2x 0.5m RCA Level 1 interconnects - way out stuff that works very well)

Audioquest Golden Gate RCA-to-RCA 0.6M

4x Emotiva 0.5M RCA interconnects
(A great value!)

LaCie USB Dual Power Sharing Cable 131046
(The poor man's KingRex uArt Y USB cable for DACs with female USB Mini-B jacks, i.e. DACport LX, ODAC, etc. Cover the 4th pin of one USB A connector with a sliver of Scotch tape to supply only data from the PC and only power from an external 5V source.)

C2G (Cables To Go) 28108 USB Y-Cable
(The poor man's KingRex uArt Y USB cable for DACs with female USB Type B jacks, i.e. Concero. Cover the 4th pin of one USB A connector with a sliver of Scotch tape to supply only data from the PC and only power from an external 5V source.)

TeraDak USB Y-Cable
(Included with the TeraDak U9VA PSU, this cable is an excellent and affordable alternative to the exceedingly expensive KingRex uArt and uCraft Y USB cables for DACs with female USB Type B jacks, i.e. Concero. - allowing only data from the PC and only power from an external 5V source. No Scotch tape required!)

Emotiva XDRCA 0.5m 75-Ohm Coaxial (digital) interconnect
(It works - but maybe too well - it's thick and stiff - uh... that didn't come out right...)

KabelDirekt (6 ft.) Pro Series Digital Audio Cable 1 x RCA Male to 1 x RCA Male
(Works great as a Coaxial interconnect - very flexible.)

2x KabelDirekt (3 feet) 1 x RCA Male to 2 x RCA Male Y Cable - Pro Series
