What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Over-engineered, hugely heavy, and XLR-balanced-only design aimed at clients who accept balanced-only systems
- 'Dual Zone' functionality provides two playback zones with independent sources for each
- The two mono preamp chassis form a sandwich with the power supply/control section in between, communicating through interlocking gold-plated 30-pin aerospace connectors, eschewing cabling between the three sections
- The heavily shielded power supply is housed in its own chassis, which is intended to sit between the boxes housing the two audio channels, incorporating internal line conditioning circuitry
- Volume control knobs are very smooth, and the volume control has no sweet spot
Product Considerations
- XLR-balanced-only design might require adapters for RCA-only devices
- The remote control was initially a 'huge, weighty affair', though a new version was almost ready at the time of review
Takeaway: The D'Agostino Relentless Preamplifier is an extremely well-engineered, high-end product intended for those wanting the best possible audio quality and are unconcerned about cost. It offers unique features such as dual-zone functionality and a sophisticated multi-chassis design.

Our Summary
Product Strengths
- The 3010 offers a wealth of controls, including six pairs of outputs which can be separately attenuated, and a 'blend' function to change stereo to mono
- Notes start and stop precisely, but in a refined manner, and grace notes appear fleetingly before disappearing
- Startlingly pure reproduction, especially noticeable on smaller-scale recordings
- Captures the ringing peal of the organ in the nether regions with great power, and distinguishes tonal fidelity
- Music 'rips without any compression', and sorts out complex musical passages
Product Considerations
- If you prefer the sound of tubes, the Boulder 3010 will not give you a sumptuous tonal balance or holographic soundstage associated with tubes, because it seeks fidelity to the source
Takeaway: The 3010 offers precision and clarity in music reproduction, making it a highly addictive listening experience. The 3010's control and accuracy allow the music to breathe freely.
