Questions about Musical Fidelity M5si Integrated

Unfortunately, Musical Fidelity is making VERY difficult to get your pre-sale questions answered.   Their web site says for product support, "If this is the case we would always suggest that you contact your local Musical Fidelity Authorized dealer or distributor".  THIS IS VERY DISAPPOINTING.

In any case, please contact the Musical Fidelity retailer or Distributor need your location and ask them.  Hopefully, they will be able to answer your questions.  Please keep us posted.   

My Musical Fidelity M6si amp is working fine in my 2-Channel home theatre system. I use my LG OLED 4K TV optical output to my Benchmark 3 HGC DAC to my Musical Fidelity amp. Every thing is working and sounds great.

Perplexity AI search said “The Musical Fidelity M5si Integrated Amplifier is not common ground[1]. It features a moving magnet phono stage input, 4 analogue inputs, fixed line level outs, and variable line level pre-outs for additional power amps[3]. The design includes a single circuit board with two independent mono block power amps and a preamp, offering well-designed channel separation[3]. The M5si is known for its high power, tonal mass, and soundstage, making it suitable for various setups, especially when paired with modern DACs or streaming DACs[3]. While it lacks digital inputs other than USB, it excels in delivering a robust and neutral sound profile with a focus on clarity in the treble range[3]. Overall, the Musical Fidelity M5si is a versatile amplifier that caters to audiophiles seeking a strong performance without compromising on quality or functionality”.

Results from Perplexity AI:  “ Based on the search results provided, it appears that some users have reported issues with the HT bypass input on the Musical Fidelity M5SI integrated amplifier, such as crackling, fading in and out, and other noise problems. Here is a summary of the key points:

- The crackling and fading sound issues seem to occur when connecting the Denon AVR-X4500H receiver to the HT bypass input of the M5SI, but not when connecting other sources directly to the M5SI[1][2][3][4][5].

- Users have tried different RCA cables but the problem persists, suggesting it may be an issue with the M5SI or the connection between the two devices[1][3].

- Some users speculate the issue could be a fault in either the M5SI or the Denon AVR, but the exact cause is unclear[1][3].

- The problem appears to be isolated to the HT bypass input, as direct connections to the M5SI do not exhibit the same crackling and fading issues[1][2].

In summary, while the exact cause is uncertain, multiple users have reported problems with noise and signal issues when using the HT bypass input on the Musical Fidelity M5SI integrated amplifier, particularly when connecting it to a Denon AVR receiver. The issue seems to be isolated to the HT bypass functionality”.
