Black Ice Audio Fusion F35 V.2 Integrated Tube Amplifier - 95 WPC* (Black or Silver)
The Fusion F35 V.2 pairs commanding bass control with tube-borne color, holographic imaging, and impressively unconstrained dynamics. HiFi Huff heard sweet, extended treble and a clear, substantial midrange, while newrecordday praised its powerful, musical authority. Balanced inputs, flexible tube rolling, and 95W-per-channel potential make it a seriously versatile high-end integrated.

Pros
Delivers unusually deep, controlled bass, strong dynamics, and high-volume composure for a tube integrated amplifier.
Creates a large, holographic soundstage with clear instrumental separation and a detailed, present midrange.
Offers flexible system matching through multiple compatible output-tube types, balanced inputs, and 4- and 8-ohm speaker taps.
Exceptional finish and design detail, with polished glass, carbon-fiber accents, illuminated touch controls, and straightforward bias adjustment.
Cons
The single mono subwoofer output limits stereo-sub flexibility unless the optional dual-sub upgrade is specified.
Tube rolling can be finicky: newrecordday experienced shutdowns when tubes did not make perfect contact or when power fluctuations occurred.
The upgraded version’s especially smooth top end may sound overly relaxed when paired with already warm or laid-back speakers.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 94/100
Reviewers describe a powerful, spacious tube presentation that combines rich tonal color with unusually firm bass, speed, and high-volume composure. The F35 is particularly praised for its holographic staging, clear midrange, sweet extended treble, and authoritative low-end control.
Transparency Resolution
92/100
HiFi Huff found the midrange clear rather than woolly or muffled, with vocal textures and fine details readily audible. Both reviewers also describe an open, unconstrained presentation, while newrecordday praised the clean, bell-like quality of cymbals.
Tonal Balance Musicality
94/100
The F35 is repeatedly characterized as full-bodied, smooth, and highly involving without becoming dark or soft. Reviewers heard sweet, extended treble, a substantial yet clear midrange, and a tube character that keeps harder instrumental edges pleasing rather than aggressive.
Dynamics
95/100
Both reviews strongly praise the amplifier's authority and lack of apparent strain. HiFi Huff heard solid-state-like speed, punch, and ease, while newrecordday reports that it remained robust and uncompressed as volume rose, with especially commanding woofer control and bass impact.
Soundstage Imaging
95/100
Soundstage performance is a consistent highlight. HiFi Huff describes a large, tall, wide, holographic stage, and newrecordday heard deeper and wider staging with vivid image separation that avoided flat, cutout-like instrument placement.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
94/100
HiFi Huff calls the F35 exceptionally polished and detailed in its design, ranking it among the most beautifully executed tube integrated amplifiers the reviewer has encountered. Newrecordday also notes the dual-chassis construction, carbon-fiber and mirrored glass panels, and LED-backlit touch controls.
Features Connectivity
84/100
The F35 provides two inputs that can be used balanced or single-ended, plus two further RCA inputs. It also includes record outputs, a subwoofer output with an available dual-sub upgrade, and separate 4- and 8-ohm speaker taps, though it does not include onboard digital playback or streaming facilities.
Value for Money
94/100
At the approximately $3,000 starting price cited by both reviewers, the F35 drew emphatic value praise. HiFi Huff calls it "crazy affordable" for the performance and finish offered, particularly versus considerably more expensive integrated amplifiers, while newrecordday considers the stock version a great buy at its asking price.
