These remarks concern the Lessloss Stellar Firewalls for loudspeakers.

My system is highly resolving, consisting of the following components (partial listing):

- Loudspeakers: PMC Twenty5 26i
- Amplifiers: Luxman 509Z Integrated; Pass XA 25 power amplifier paired with Icon Pro 4 SE balanced passive preamplifier
- DACs: Lamipizator Baltic 4; Holo May ‘KTE’
- CD transport: Jay’s Audio CDT MKIII
- Streamer : Matrix Element S
- Speaker cables : Audience AU24 SX ; JPS Superconductor V
- Interconnects : Audience AU24 XLR & RCA ; JPS Superconductor V
- Digital : Curious cable (blue) USB ; Tubulus I2S & Aes/Ebu
- Power cables: Lessloss; Isotek; Xindak
- Power conditioner: Audioquest Niagra 1200.
- Decoupling devices: Auva 100s and 50s; Symposium Padz and Roller Blocks

Upon inserting the Stellars into the system I was presented with a vividly clear, bright sound quite unlike the original Lessloss firewalls for speakers that I had been using for a few years. Initially, the sound was somewhat harsh accentuating the high frequences somewhat to the detriment of the mids and lows. However, I was correct to assume that some burn-in was needed: after approximately 20 hrs the Stellars appeared to settle, and I began enjoying a clear, transparent, slightly forward sound across the frequency spectrum. As I prefer a more relaxed sound, less forward, I experimented with speaker positioning: I discovered that by moving the speakers forward, not back, and increasing their separation, I achieved a more neutral, balanced and extended soundscape, any residual brightness or glare being ascribable to the materials/recordings. The noise floor is considerably lowered, graininess is virtually absent (depending on the source material), resolution is greater, listening levels can be moderate with no loss of musical fidelity.

In short: Not only are the Stellar firewalls a considerable improvement over the regular speaker speaker firewalls, they are a major addition to the audio excellence of my system.
