BLOG #99. StereoPravda Will Unveil Its Newest Earphone Model At The Moscow Hi Fi & High End Show-2021

At the Moscow hi Fi & High End Show (May 21st-23rd, hotel Borodino) StereoPravda will unveil its newest model -StereoPravda SPearphone SB-3.5RU.

The earphone uses four Balanced Armature drivers, however as one of the drivers is a double-stacked one, so the number of drivers in Knowles’ SKUs is three, that is why we use “3.5” in the model’s name.

“RU” – within its various possible implications – actually stands in its name for “Ripped Up”. We “rip up” one of the BA-drivers, that is, we opened it as a tin can, so we can use its direct sound radiation (as opposed to the nominal bellows-type BA-drivers sound radiation) and also to position the driver’s sound radiation ON AXIS with the tympanic membrane’s sonic response (the deep insertion of the earphone at the vicinity of ear canal Second Bend will facilitate reaching for that goal due to relatively close distance to the ear drum).
As a result of the lower sensitivity of the “ripped up” BA-driver compared to the stock one, the “high-mid” section of BA-drivers in the earphone is connected directly to the earphone amplifier with NO matching resistors in-between (which does help to remove some additional distortions from the in-series additional passive elements).

Our SB-7 model is still the flagship model in our audiophile earphone line called StereoPravda SPearphone (as a whole, we must admit, it’s been always conceptually intended not for faint of the heart), although the newest addition to the line allows some of the best BA-drivers’ sonic attributes to really shine through in a very unique way.

StereoPravda SPearphone SB-3.5RU earphone’s MSRP is $2 500.
