Στo 6moons ετοιμάζουν reviews του νέου line-up της Coda (όχι Koda, Coda - όπως λέμε www.coda-continuum.com !).
Προς το παρόν υπάρχει μόνο ένα preview αλλά είναι αρκετό για να δούμε ότι εξακολουθούν να βγάζουν "γομάρια" ενισχυτές σε σχετικά προσιτές τιμές. :violent:
Aντιγράφω τα spec των μονομπλόκ ($10.000 το ζευγάρι, τα 50 πρώτα watt σε τάξη Α):
"Specifications are 450/900 watts into 8/4 ohms and the amps are stable into a 1-ohm load. Bandwidth is DC or -3dB at 5Hz to 100kHz depending on the chosen input. Distortion is < 0.03% from 10Hz to 20kHz, with both channels driven into 4 through 8 ohms. Gain is 26dB, current capability 150 amperes peak, slew rate 50 V/microsecond, input impedance 50Kohm and 1Kohm for RCA and XLR, output impedance 0.04 ohms from 20Hz to 20kHz and noise better than 110dB referenced to rated output." The following is for the drag strip fans amongst us: "The power supply uses a 3kVA toroidal transformer with independent rectifier and 80,000uF of capacitance." That's serious iron. "Weight is 62 lbs and dimensions are 17" x 6" x 14" WxHxD."

"When Coda Technologies' Mark Ward inquired about a review on their new X Series, I hadn't kept up with developments in Sacramento since my review of their Unison integrated. They now had 450-watt CX monos, a matching CSX stereo version at 330wpc and the 220wpc CSi Limited integrated, all sharing the same VMosfet front end. The 'C' designation refers to Continuum, once a separate Coda brand, now an integrated entity. It's no secret that Coda built electronics for InnerSound and Legacy. Add that the company's formation goes back to the early Threshold days. To hear the latest iteration of upscale muscle amps from so long-lived an outfit was a rather attractive proposition.
With Coda's ramped-up EU distribution, dispatching loaners from French importer Kapra Audio to Cyprus would prove easy so I signed on.

"X features a wide range of design topologies and components ported from both the broad lineage and the most recent advances in Coda products and design topologies. This include a high non-bridged current design; a new vertical Mosfet voltage gain stage; a true standby mode that turns output bias current on and off; parts upgrades by way of Mills custom copper-nickel alloy wire-wound emitter resistors, IXYS high-speed rectifiers, Black Gate and RelCap capacitors, Vishay resistors, WBT top line gold binding posts and WBT or Vampire OFC RCA connectors.

"The CX monoblock uses a similar output stage topology to that of the flagship Coda Amplifier System 200 whereby all output devices are paralleled rather than bridged to provide exceptional power and low-impedance drive capability. In addition, the classic bridged-design drawbacks of decreased load intolerance and redistribution of harmonics towards the unfavorable odd harmonics are avoided. Differential JFET inputs and a new vertical Mosfet voltage gain stage provide exceptional rejection of noise and contribute to the circuit's inherent DC stability. This allows direct-coupling at the balanced input without servo circuitry. The front end is designed to provide a slew rate of 50V/us without entering Class B operation as is common in many other designs. The amplifier's excellent high frequency design insures superlative linear operation. This latest-generation Coda output stage is capable of producing peak currents in excess of 125 amperes peak with unmatched linearity and speed. The bias section is designed to produce a precision transition with no abrupt changes in distortion or output impedance. This "Precision Bias" technique yields seamless performance regardless of the complexity of the load impedance. With such linearity and bandwidth, only 6dB of feedback are used to maintain damping factor while permitting the minimal-value custom emitter resistors to provide current limiting only under such extreme conditions that would exceed the output stage's high current capabilities. One advantage of this is a high degree of immunity from interactions with complex speaker loads or cables."

Και μερικά λόγια για τον Preamp, απο τον κατασκευαστή:
"Features include 1 balanced and 3 unbalanced inputs; tape and processor loops; balanced and unbalanced outputs; full remote control including mono, mute, learning and multi-device preprogammed functions; the latest digitally controlled attenuator utilizing the Burr-Brown PGA2320 SMT device; ultra-high class A biased JFET output stage with programmable gain on all inputs from unity to +18dB; shielded toroidal transformer and over 19,000uf of low-ESR capacitance utilizing top line BlackGate capacitors for maximum filtering for the multiple audio section analogue voltage regulator outputs. There are also carefully selected and evaluated audiophile-grade parts, rigorously tested using both objective and subjective techniques including PRP and Holco audio resistors; BlackGate, Nichicon and RelCap capacitors; Fairchild Stealth rectifiers and Vampire pure billet copper RCA connectors. The enhanced styling with graphite anodize and stainless steel accents matches that of the new Coda CSX and CX amplifiers.
"Specifications include a frequency response of -3dB at 5Hz and 200kHz; distortion of <.01 % from 10Hz to 40kHz at 5V peak into 600 ohms or higher shunted by 1000pF or less; independently variable gain on all inputs from unity to +18dB in 1dB steps; a maximum output of 10 volts peak; noise of >100dBA referenced to 1-volt output; 20K input impedance on RCA or XLR, output impedance of 50/100 ohms RCA/XLR; crosstalk of 70dB at 20kHz; power consumption of 10 watts; weight of 14 lbs; dimensions of 17" W x 9.75" D x1.75"H; and lastly, a warranty of 10 years."
