V5 Elektra – Hi-Fi+


“The IsoTek V5 Elektra needs no apologies or excuses; you plug it in, you hear what it does, you buy it.“

Alan Sircom, September 2022

V5 Corvus – lite magazin

“..the reproduction has more transparency and details, greater plasticity and spatiality, better dynamics and greater precision, more volume especially in the bass and overall increases in coherence and relaxation.”

Volker Frech, September 2022

V5 Polaris –


“Komt als een openbaring”

Olaf Sturm, oktober 2022

V5 Aquarius –


“..the IsoTek Aquarius V5 .. has noticeably improved the performance of my hi-fi system.”

Recommended – Reference Class

Jonas Bednarz – October 2022

hi-fi+ Product of the year


“V5 Titan improves upon that performance in every way. Once you’ve (not) heard it working, it’s hard to go back.”

Hi-Fi+ Magazine

V5 Elektra
“To further improve performance on an almost perfect system is extremely difficult. However, IsoTek V5 Elektra proved that it play an important role to the system, doesn’t matter it’s a Wireless Loudspeaker- or a High End System, sonically V5 Elektra is very neutral didn’t add any coloration to the sound. Highly recommended!“
Martin, Audiotechnique  – January 2023
V5 Sirius – i-fidelity

“we are also aware of positive sonic effects of this magnitude from other mains filters, but never before has there been this result with a three-digit price tag.”

V5 Elektra

“The IsoTek V5 Elektra needs no apologies or excuses; you plug it in, you hear what it does, you buy it.“

Alan Sircom – April 2023


V5 Sirius

“..the common belief that a power filter will choke your dynamics didn’t seem to apply here. On the contrary, the bass even gained punch, and the brass instruments definitely increased in details and intensity. Overall, the recording felt “awakened”, more alive and diverse.“

Daniel Březina – June 2023

V5 Elektra

“V5 Elektra zorgt voor een zuiver, dynamisch en neutraal uitgebalanceerd geluidsbeeld.“

Fritz I. Schwertfeger – Juli 2023

V5 Sigmas

“The jump from EVO3 to V5 might be considered ‘evolution’ and not ‘revolution,’ but only on paper. In real-world performance terms, it’s a honking great big step forward in sound….. EVO3 Sigmas made decent systems sound more realistic, and the V5 Sigmas improves upon that realism significantly.”
Alan Sircom – October 2023

V5 Sigmas

“The bass has greater articulation and definition, and the high frequencies have more air and precision.“

hi-fi+ – December 2023

V5 Sigmas –

“Het gebruik van de V5 Sigmas tilt elk goed systeem naar een muzikaal niveau dat nauwelijks kan worden bereikt door het vervangen van apparaten.“

Stephan Schmid – December 2023

V5 Sigmas – Product of the year

“.. it surpasses what we’ve had the opportunity to hear in the power filter segment so far.“ 

Daniel Březina – October 2023
