What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Our summary
Product Strengths
- The Freya+ offers a balanced design with XLR inputs and outputs, a 128-stepped attenuator, and dual single-ended outputs
- Multiple reviews mention its versatility due to its three distinct circuit configurations—passive, solid state, and tube—effectively functioning as three preamplifiers in one
- The Freya+ excels at accurately reproducing the natural timbre of instruments, offering a transparent, clear, and ultra-resolved sound across the entire musical range
- Reviewers highlight the improved features over previous models, including a better remote control, upgraded chassis, and a redesigned tube stage that lowers the noise floor
- Connectivity options with XLR inputs and outputs, a 128-stepped attenuator, and dual single-ended outputs
Product Considerations

- Some find the remote control's volume adjustments to be too sensitive, making minimal incremental changes difficult
- The placement of the power switch on the back of the unit is inconvenient
- The unit gets hot in active tube mode
Comparisons (according to reviewers)
- Compared to the Schiit Saga+, the Freya+ includes a FET buffered passive output or active tube amplification, and more inputs/outputs
- Compared to the Rotel RC-1572 MKII, the Freya+ has a clear edge due to bigger, more three-dimensional sound, and more dynamically engaging sound with Freya's tube mode engaged
Takeaway: The Schiit Freya+ is a versatile preamplifier with multiple modes and flexible connectivity, offering great sound quality. It provides an accessible way to explore tube amplification with added convenience.

Product Considerations
- The headphone output may not have enough power to drive more difficult audiophile headphones
- Cambridge Audio's Duo has no MC loading options, instead fixing it at 100 ohms, with gain fixed at 60dB
- The Alva Duo's volume control only controls the headphone output
Comparisons (according to reviewers)
- Cambridge Duo doesn't quite match the punch delivered by Rega's Award-winning Fono MM MK3
- The Cambridge Duo's performance was everything the Linn's was, but just a tiny smidge better than a Linn Majik 1P preamp from 1996
Takeaway: The Cambridge Audio Alva Duo is a well-specified, dynamic performer that offers great value for its price, and would be great as a starter phono preamp or in a small system. It also handles both moving magnet and moving coil cartridges.
