« Last post by Joe.siow on April 27, 2024, 07:17:43 PM »

For sale is a mint unit of Concert Fidelity CF-080LSX3 V3 hybrid preamp with remote control

This is a work of art from Masataka Tsuda san, and is one of the finest preamp in the world and the best I have owned
This unit features dual 12AU7 preamp tubes and EZ81 rectification tube in the power supply

Sound wise, this preamp is extremely transparent sounding, with excellent microdynamics and natural timbre
The bass is powerful, taut and fast
The mids is hard to describe, as it has the best traits of both tube and solid state. It is transparent yet musical and natural sounding
The top end is well extended, open with excellent dimensionality

It has 4 RCA inputs and 1 RCA output with selectable gains of 6dB or 12dB
Remote control for volume selection is also included

This are our KS AV SOLUTION Goals.
1. Dialog clarity - As the majority of the story in any movie or show is conveyed by dialog, it is essential that it be clearly intelligible.
2. Localization accuracy - Movie soundtracks are replete with sound effects placed throughout the sound field to increase immersion, realism, and dimensionality of the narrative. These pin-point sounds can include cars, airplanes, punches, gunshots, moving objects from left to right or from top to bottom, etc. Some of the sounds are targeted to positions where speakers are expected to be, and others are in-between speakers, formed by "phantom images."
3. Sound movement - The sound designer or mixer of media content can decide to move pin-point effects around the sound field to extend the action on screen, further enhancing the sense of realism for the audience. This can include things like cars traversing the screen or headed back behind the audience, airplanes flying over, or any other sounds that put the audience in the middle of the action. The sounds will move between speaker locations and phantom images, so timbre-matching is important.
4. Sound field immersion and envelopment - Many scenes in programs call for an even, enveloping, and immersive sound field. Sounds to set an ambience, such as wind and rustling leaves, or music and reverberation can be employed by the sound mixer and should be distributed evenly throughout the space without specific localization. Immersive sounds may involve any combination of speakers, with timbre matching also being important.
5. Tonal balance (timbre) - Also known as spectral balance or timbre, this basic frequency domain notion is sometimes one of the hardest to describe, measure, and tune. Ideally, all tones in the audible spectrum are reproduced in the entertainment space, appropriately balanced in a way that matches the original production environment. The broader the frequency range of a sound, the more it may be affected by its reproduction accuracy. Deviations in tonal balance by as little as 1 or 2 dB can profoundly affect the audibility of sound effects, the character of music, spatial balance, and frequency balance of the soundtrack.
6. Dynamic range - Multimedia soundtracks can contain upwards of 100 dB of dynamic range — the difference between silence and the loudest burst of sound. On the quieter side may be music passages, ambience sounds, subtle cues, reverberation tails, and many other types of subtle sounds that need to be reproduced faithfully. All sound peaks such as gun shots and explosions should be reproduced without distortion or limiting in the amplifiers or speakers.
7. Bass impact - Multimedia soundtracks use a lot of bass effects to convey action, realism, mood, and dynamics. They can extend to 20 Hz and lower with peak levels of up to 115 dB SPL. Add the complexity of standing wave resonances in the middle of the bass range and it becomes evident that is an inherently challenging range of signals to reproduce. It is very common to have wide bass variations from seat to seat, with differences of up to 25 dB in frequency response. However, dynamic, punchy, loud bass is a big favourite of audiences, so it is crucial to get it right.
8. Audience coverage - Seat-to-seat variations in sound quality should be reduced to a minimum so that everyone in the entertainment space has a similar experience. Bass variations are the toughest to control, followed by localization and immersion. There are many ways to ensure consistency throughout the space, using proper equipment selection, placement, acoustical control, and calibration practices.

HiFi Audio Equipment Discussion / Re: Tube amplifier basics

« Last post by Ed on December 24, 2023, 10:18:14 AM »

Hi Watchdog,

Thanks for your sharing which I find very informative and practical 👍

Just a quick question if cost permitting whether the usual recommendation of tube preamp with ss power amp is necessarily better vs the other way round with ss (or passive) preamp and tube power amp? I listen to a broad range of music particularly classical music and thus value transparency above all other attributes so that I can better hear each performance/recording as it is. My limited experiences has so far led me to using a ss preamp with tube preamp, with the thinking/feeling that it's probably better to keep the transparency as far upstream as possible and leaving the nice bits of coloration towards the end 😅 I know all these are highly dependent on the gears used but just good to learn from you and others if such rationale makes any sense at all and real life experiences 🙏

Many thanks,
Ed
