Pursuit Perfect System – July 2024
hi-fi+ EDITOR`S CHOICE AWARD 2024 for the
V5 Titan
« I’m going to stick my neck out and say the IsoTek products are the world’s best.”
TONEAudio – July 2024
“…fun, effective and reasonably priced, the V5 Titan, is highly recommended!”
Hi Fi Review Hong Kong – June 2024
“.. it surpasses what we’ve had the opportunity to hear in the power filter segment so far.“
Daniel Březina – October 2023
“The use of the V5 Sigmas raises any good system to a musical level that can hardly be achieved by replacing a single device.“
Stephan Schmid – December 2023
“The bass has greater articulation and definition, and the high frequencies have more air and precision.“
hi-fi+ – December 2023
« 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
“Using the V5 Elektra ensures a clean, dynamic and neutrally balanced sound image.“
Fritz I. Schwertfeger – July 2023
“..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
“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
“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.”
Olaf Sturm – April 2023
