The Fostex TH600 full-size headphones' sound is downright addicting. They take you inside the sound of a recording like few other headphones can. Unfortunately, Fostex's U.S. distribution of its high-end headphones is very limited (it's a Japanese company), but Fostex dealer Moon Audio was kind enough to send over a sample pair of TH600 headphones ($1,299) fitted with an extra-cost Black Dragon V2 cable. Fostex also offers much less expensive models, including the $129 T50RP, but the company mostly caters to the pro sound market.

The TH600 has large 50mm drivers, matched with an unusually powerful … Read more

Head-Fi is a national headphone club, and I went to the local meeting in Babylon, N.Y., last Saturday.

The vibe was friendly, and it was great to hear Head-Fi members' home-built gear, but there were a few surprises popping up from the headphone and electronics manufacturers in attendance.

Logitech Ultimate Ears' Personal Reference Monitor in-ear headphones feature a new twist on custom-molded-to-your-ears headphone design. Lots of brands now make custom in-ear headphones, and Logitech's have been among my favorites for years, but the upcoming Personal Reference Monitor takes the personalization to the next level. Once your ear canals' &… Read more

Red Wine Audio makes some of my all-time favorite headphone amplifiers, but they're pretty expensive. The Isabellina HPA LFP-V Edition, for example, runs $2,500; it was designed and built in Vinnie Rossi's small factory in Durham, Conn. The Isabellina is more than just a headphone amp, it features a spectacularly good digital-to-analog converter and a hybrid transistor/vacuum tube audio amplifier. While the amp can be run off an AC power outlet, it sounds best powered by its built-in 25.6 volt Lithium Iron Phosphate battery pack. The battery can play for up to 10 hours, and … Read more

I've reviewed and auditioned a lot of headphone amplifiers over the years, but Red Wine Audio's Isabellina HPA LFP-V Edition stood out from the pack. The amp improved the sound of almost every headphone I used with it.

Priced at $2,500 the Isabellina is very much a high-end audio product. Designed and built in Vinnie Rossi's small factory in Durham, Conn., the headphone amp's elegant functionality belies its technical sophistication. Rossi started Red Wine Audio in 2005, and before that he worked on high-speed laser transmitters for Bell Labs.

The Isabellina is more than just a headphone amp; it features a spectacularly good digital-to-analog converter and a hybrid transistor/vacuum tube audio section. While the Isabellina can be run off an AC power outlet, it sounds best powered by high-current lithium iron phosphate (LFP) batteries. Rossi claims "The batteries use organic, phosphate-based material, providing an ideal combination of performance, safety, reliability and environmental friendliness...in fact, more so than any other rechargeable battery technology."

The amp's digital connectivity options include USB, Coax, and Toslink/optical inputs; there are no analog inputs. The Isabellina has analog outputs, so it can be used as a stereo preamplifier, with a separate power amp to drive speakers, or a digital-to-analog converter in a hi-fi system.

The Isabellina features old tech 16-bit, non-oversampling digital-to-analog converters. Rossi acknowledges the latest chips' specifications look more impressive on paper, but he thinks most of them (even some really expensive ones) sound "quite sterile and artificial" in comparison. The Isabellina will work with digital sample rates up to 192kHz, but it will only playback with 16-bit resolution. … Read more

I've never heard anything quite like the Audeze LCD-2 before. This headphone somehow produces extraordinary clarity, openness, and articulation, but without exaggerated detail or annoyingly overdone treble. The Audeze LCD-2 is a game changer; no wonder it's getting raves from the online high-end mavens at Head-Fi. Audeze's co-founders, Alex Rosson and Sankar Thiagasamudram, are onto something.

The headphones feel great in your hands. Build quality is robust, but the design is nowhere as sleek as Sennheiser's high-end headphones. The LCD-2's impedance is 50 ohms, and the maximum power handling is a remarkable 15 watts, which corresponds to a superloud 133 decibel output! You'd be hard pressed to blow this headphone up by playing it too loud. The LCD-2's tonal balance is noticeably warm, but I never felt it was smearing detail or lacking in resolution. It also sounds great at quiet listening levels. Sure, one of the advantages of headphones is you can play music as loud as you want, but it's still nice to have the option of listening low, without losing detail or presence.

The LCD-2's unusual technology (planar magnetic, or orthodynamic) is currently only used by one other headphone manufacturer, Hifiman, and I raved about its HE-5 headphones last year. The LCD-2's huge headphone drivers (6.17 square inches each) are many times the area of any dynamic headphone I know of. Audeze's very large drivers project sound over most of your outer ears, and that may be the reason why the LCD-2 sounds more speakerlike than other headphones. It weighs a rather hefty 19.4 ounces (550 grams), but I found it comfortable over very long listening sessions. The LCD-2 is handmade in the U.S., with real lambskin leather-covered earpads, and real Caribbean rosewood earcups.

The LCD-2's headphone cable is detachable, via very secure mini-XLR plugs, and is therefore user replaceable. I opted for a Chain Mail 8, an audiophile upgrade cable from ALO. It seemed to enhance everything about the LCD-2's sound, which was awfully good with the stock cable.

The LCD-2's big drivers make bass, oh boy, do they make bass. If you really want to hear amazing bass, you have to get "Kodo: The Heartbeat Drummers of Japan" CD. The drums' big sound is beyond the abilities of most headphones, but here, over the LCD-2, the drumbeats were clear and powerful. Not the sort of flabby, thick, or overdone bass you get from DJ headphones, no, I'm talking about pitch-accurate, highly defined bass that also digs deeper into the very low bass regions than other full-size 'phones.… Read more
