Short answer: the ELAC Debut 3.0 DB63. It ranks #50 of 203 bookshelf speakers by sound quality (rated 4.2/5) at $499 and is still sold new; the SVS Ultra Bookshelf ranks #94 (rated 3.9/5) and is discontinued, so it is only an option used. The SVS Ultra Bookshelf’s replacement, the SVS Ultra Evolution Bookshelf, is rated 4.0/5.
The ELAC Debut 3.0 DB63 is the better-sounding pick. 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Watch for: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow.
What the SVS Ultra Bookshelf does well: Noticeably more tonally neutral than the cheaper SVS Prime Bookshelf, with response staying within about -3dB/+1.5dB on average: a genuine step up in linearity for roughly double the price. Watch for: Still has a boosted upper mid-range/mid-range area, though less severe than the Prime: the reviewer suspects a baffle-step or tweeter-level issue rather than a resonance, giving mixes a slightly forward, occasionally tinny character.
Buy the ELAC Debut 3.0 DB63. It is rated higher for sound quality; the SVS Ultra Bookshelf is no longer sold new.

Older model: the ELAC Debut 2.0 B6.2 (ranked lower, rated 3.5/5).
Same family: the ELAC Debut 3.0 DB53 (smaller bookshelf, estimated 3.9/5), the ELAC Debut 3.0 DF53 (smaller floorstanding, estimated 4.2/5), the ELAC Debut 3.0 DF63 (larger floorstanding, rated 4.2/5), the ELAC Debut 3.0 DC53 (smaller center, estimated 3.4/5) and the ELAC Debut 3.0 DC63 (larger center, estimated 3.5/5).
Pros: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Shallow bass rolloff (F3 76Hz, F10 40Hz) allows placement close to a wall without excessive boominess, useful for smaller living rooms. Solid measured performance for the price: on-axis linearity within about 2.5dB, impedance dipping only to about 4.4 ohms (easily AVR-driven), and roughly 20-26dB of usable dynamic range. A clear improvement over its sibling ELAC DB62, which has a sibilance issue tied to the crossover that can’t be fixed with EQ. Wide horizontal radiation of about ±60°, giving a spacious soundstage. Distortion looks good at a moderate 86dB and still reasonable at 96dB. Takes well to EQ correction: the reviewer provides a specific filter set (a low-shelf boost at 650Hz plus peaking cuts/boosts at 550Hz, 660Hz, and 3kHz) that meaningfully smooths out its known deviations. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 86.2dB.
Cons: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow. A high-Q resonance around 650-750Hz shows up clearly in measurements, though the reviewer couldn’t reliably hear it in his own A/B testing. A dip around 2-3kHz (roughly 1-2dB) slightly reduces speech intelligibility and attack in the upper midrange. Directivity droops above about 2kHz as the midwoofer narrows toward its beaming frequency while the tweeter’s pattern behaves differently: an inherent trade-off of physically separated drivers that can’t be fully corrected without introducing other issues. Multitone distortion crosses the reviewer’s 3% threshold in the 200Hz-1kHz range, and adding a subwoofer at an 80Hz crossover only modestly reduces it. Toeing the speaker away from the listener loses noticeable top-end air and cymbal energy, giving a softer upper register. Practical loudness ceiling is around 90dB at typical listening distance before midrange distortion and bass attack begin to degrade. Still needs a subwoofer for extension below about 40Hz.

SVS Ultra Bookshelf: $1,200 per pair Discontinued eBay
Newer model: the SVS Ultra Evolution Bookshelf, ranked higher, estimated 4/5.
Pros: Noticeably more tonally neutral than the cheaper SVS Prime Bookshelf, with response staying within about -3dB/+1.5dB on average: a genuine step up in linearity for roughly double the price. Slightly higher sensitivity than the Prime (about 87.8dB) with similarly wide, consistent horizontal radiation. Toeing the speakers out about 30 degrees smooths the in-room response nicely if the on-axis tonal balance runs a bit forward for your taste. Distortion and dynamics hold up well; this is a mature, well-regarded design (roughly a decade old at review time) that’s aged better than many contemporaries. Measured bass extension of 69Hz (-3dB), with a measured sensitivity of 87.8dB.
Cons: Still has a boosted upper mid-range/mid-range area, though less severe than the Prime: the reviewer suspects a baffle-step or tweeter-level issue rather than a resonance, giving mixes a slightly forward, occasionally tinny character. Bass extension is modest for the price (F3 69Hz, F10 48Hz measured): SVS is clearly counting on you pairing this with one of their subwoofers rather than expecting full-range performance from the bookshelf alone. Measured minimum impedance dips to about 3.8 ohms, so a 4-ohm-stable amplifier is recommended rather than a basic 8-ohm-only AVR. Radiation pattern is wide (around 80°), wider than the reviewer’s typical ~60° sweet spot preference, so acoustic treatment on nearby walls helps tame reflections and keep the off-axis response from diverging too much from on-axis. Discontinued; SVS replaced the Ultra line with the Ultra Evolution series.
