TEST OF STAX SR-L300 & SRM-252S (ADVANCED LAMBDA SERIES)
I've had this set for a couple of years now, and thought I had done a review that I had presented, but I haven't.
That's why I'm doing it now.
The SR-L300 is said to be the gateway to true HiFi, and costs quite a bit more than regular headsets - about $455 for the headset, plus about $545 for the required amplifier STAX SRM-252S - about $1,000 in total.
Here are the specifications:
* Type: Push-Pull electrostatic oval sound element, Open-Air type enclosure
* Frequency Response: 7 - 41,000Hz
* Capacitance: 110pF (including cable)
* Sensitivity: 101dB / 100V r.m.s. 1 kHz
* Bias Voltage: 580V DC
* Left & Right Channel Identification: 'L' and 'R' indicated on the arc assembly, solid line (left) and dotted line (right) on cable
*Ear Pads: High-quality synthetic leather
* Cable: OFC parallel 6-strand, low-capacity wide cable, 2.5m full length
* Ambient Temperature & Humidity: 0 to 35ºC / 90% max. without condensation
* Weight: 11.4oz without cable / 15.8oz with cable
I tried STAX Lambda (as this actually is) already 40 years ago - these were in solid aluminum, while the new ones are in simple plastic.
The world was never the same again, because the sound was so infinitely better than everything else, with a sub-bass that almost tore my head off and a perspective and details that shocked with their precision.
What a dynamics !
The new version gives the same impression, and my otherwise quite good beyerdynamic T70s have no chance against this set !
So the sound experience is absolutely fantastic, but they are not very user-friendly:
They require a special connection via LINE OUT or PRE OUT, and cannot be connected directly like other sets can.
This presents some challenges in terms of connection.
They are also quite clumsy to use, as they sit loosely on the head and change position easily.
The cable is a nightmare with its flat wide design; it wraps around the legs, and often gets caught in them when you stand up, which results in the set falling to the floor, which in turn reveals how weak the frame is - the arc breaks after a few falls.
The arc is also an expensive spare part.
CONCLUSION:
Despite all this, the Lambda set corresponds to some of the best on the market in terms of sound and has to get my recommendation - if you once hear Lambda, you will never consider buying (or using) anything else.
PROS:
* A heavenly sound experience in top class - State of the Art
CONS:
* Cannot be connected as normal
* Clumsy cable
* Weak chassis that breaks easily
FINAL CONCLUSION:
RECOMMENDED
