Based purely upon the 2-channel 'high-end music system' products i've personally heard,my choices would be:
Aesthetix & Aesthetix 'Signature' (Integrated amp.,outstanding hybrid pre/power amps. & phono stages)
Audio Research (CD players,DAC's.,integrated amps.,pre/power amps. & phono-stages.ARC components organic,naturally rounded & near-analogue sound,will have clients salivating - providing they've the means!)
Avalon Acoustics (Innovative design & use of technology.Eerily realistic & revealing speakers)
B&W (iPod dock,600 & 800 series speakers)
Bryston (Great CD player for the money - when properly set-up,DAC's,electronic crossovers,integrated amps.,wide variety of very competent pre/power amps.,external power-supply & a 20 year guarantee on most products.Says it all)
Chord Electronics (Highly resolving CD players - Even if they are quirky & un-ergonomic designs,DAC's.,integrated amps. & pre/power amps.)
EDIT:EMM Labs [Upsampling CD/SACD players,transports & DAC's.Which use Ed Meitners' proprietary software to upsample CD's(44.1kHz to 48kHz) & SACD's(2.822MHz) from their native sampling rate to double DSD's sampling rate ie. 5.644MHz!]
GamuT (CD player,integrated amps.,pre/power amps. & speakers)
Michell (Tonearms,turntables & accessories)
Nagra (Awesome CD player,DAC's.,pre/power amps.)
Plinius (CD player,integrated amps. & belting pre/power amps. - esp. Tautoro/SARef. combo.)
Peak Consult (Truly engaging,natural sounding speakers)
PMC (Speakers which punch well above their class.Perhaps,a nod of recognition to those not of the hoy-paloy!)
Rega (CD players,integrated amps.,pre/power amps.,speakers,tonearms,tuners,turntables & accessories- see above!)
EDIT:Simaudio - Moon (CD players,DAC's,excellent pre/power amps. - esp. 3 chassis P-8/W-8 combo.,multi-channel amps. & processors)
SME (Power-supplies,tonearms,turntables & accessories)
Sonus Faber (Always great looking but,now,even greater sounding speakers - particularly the Cremona & Homage collections.Shedding their previous saccharin syrupy,warm sound for one naturally smooth & sweet but,much better at resolving & revealing the music)
Spectral (CD player,interconnects/speaker cables,integrated amps. & mind-blowingly brilliant pre/power-amps.With expressive dynamics,holographic imaging & 3-dimensional sound-staging you'd be willing to give your right arm for!)
EDIT:Tannoy (Dual-Concentric driver loudspeakers.Produce a really coherent & grown-up sound - esp. Prestige series)
TEAC Esoteric (crisp sounding,full-scale dynamics retrieving & incredible detail resolving CD/SACD players,DAC's.,integrated amps.,pre/power-amps.,master-clock & speakers)
VPI (Synchronous drive system,tonearms,turntables & accessories)
OK.So i chose more than ten.
If i had to,i'd consider removing(only consider mind) Bryston,GamuT & Rega.
Any thoughts?
