for furthur reading and understanding..... here is the 26 page "cut-sheet" on the Texas Instrument TAS5152 chip...... some very interesting block diagrams http://focus.ti.com/lit/ds/symlink/tas5152.pdf from page 20 - Theory of Operation "In an application with PWM switching frequencies in the range 352 kHz to 384 kHz, it is recommended to use 33-nF ceramic capacitors, size 0603 or 0805, for the bootstrap supply. These 33-nF capacitors ensure sufficient energy storage, even during minimal PWM duty cycles, to keep the high-side power stage FET (LDMOS) fully turned on during the remaining part of the PWM cycle. In an application running at a reduced switching frequency, generally 192 kHz, the bootstrap capacitor might need to be increased in value." seems to me that the TI switching frequencies are much lower than the Tripath switching frequencies of 600 to 700 kHz and sometimes even up to 1.5 mHz

Pretty impressive. ---------------- no - it is not just a marketing designation you can do some reading on the technology on the following 6 page pdf from the tripath website http://www.tripath.com/downloads/an1.pdf some excerpts: "The audio quality of Class-D PWM amplifiers is inferior because of fundamental problems with the PWM approach. The output transistors are not perfect switches and are not perfectly matched, and this causes distortion. The switching of the transistors causes "ground bounce, which adds noise. There is crossover distortion caused by the dead time between when one of the output transistors turns off and the other turns on (like a Class-AB amplifier). Finally, all the energy of the triangle waveform cannot be removed from the audio band with a simple low-pass filter, and what remains is distortion. Instead of using PWM, Tripath Class-T amplifier processors use proprietary algorithms and techniques to create the modulation that drives the switching transistors. A Class-T amplifiers processors learn the characteristics of the output transistors. Then, based on the analog input signal, they switch the output transistors with exactly the right timing to eliminate Class-D PWM problems: transistors not being perfect switches, ground bounce, output transistor mismatches, dead-time distortion and residual energy from the oscillator in the audio band. The result is a high power efficiency, audiophile-quality audio amplifier a Class-T amplifier. If one were to compare the waveform before the output filter of a Class-D PWM amplifier to a Tripath Class-T amplifier, some significant differences would be evident. The waveform for a Class-D PWM amplifier would be a pulse-width varying digital signal at the fixed, 100- 200kHz, frequency of the triangle wave generator. The waveform for a Tripath Class-T amplifier would be a complex digital waveform of varying frequency. A Class-T amplifier switches the output transistors in a fashion similar to spread spectrum technology, at a varying rate up to 1.5 MHz and averages 600kHz to 700kHz. What this difference means, in addition to significantly better audio quality, is that a Tripath Class-T amplifier can use lower-cost inductors and capacitors for its output filter while obtaining the same amount of filtering as a Class-D PWM amplifier. A Class-T amplifier also has lower electromagnetic emissions than a Class-D PWM amplifier broadening its potential application." meanwhile - other "digital" amplifier chip manufacturers sometimes refer to their amps as PWM amps - even Class D Texas Instruments is one that uses that nomenclature http://www.electronicstalk.com/news/tex/tex685.html "Texas Instruments is the clear leader in the digital amplifier and Class D audio circuit market", said Will Strauss, founder and Principal Analyst, Forward Concepts, who recently released a report entitled "Emerging markets for Class D power amplification".

Thanks again. ---------------- because you do like to crank it up on occassion and your price range, i would recommend a good solid state amp that is known to work well with horn speakers i will recommend the amp that i use with my KLF-30's that has the guts to handle anything and everything that i can throw at them it is a Carver Professional ZR1000 digital amp based upon a tripath digital chip..... it provides 225 watts per channel @ 8 ohms - plenty of headroom for your LaScalas and yet it has a very good sound at low levels with a very smooth sound in the upper registers (btw - no connection at all with Bob Carver and Sunfire Corp) there have been several recent threads on the Sonic-T digital amp and the Teac digital amp.... these low power and low cost designs sound great but will not allow you to "crank it up" there is none of the harshness commonly associated with other solid state designs.... and i do occassionally like to listen to recordings of Maynard Ferguson (screaming trumpet player).... if this amp can make maynard's recording sound good on my KLF-30's, it can make almost any music sound GREAT on horns!!! it has been called the "poor man's bel canto"..... (bel canto is a digital amp that costs well over $2000).... the unit does come with a fan for cooling - but after talking with carver tech support i disconnected the fan and the amp never even gets warm (fan has been disconnected for the entire time i have owned the amp) http://www.carverpro.com/zramps.html you can find these amps occassionally on audiogon and ebay (as well as the larger ZR1600 model)....but a brand new model online goes for about $825 http://store.yahoo.com/djgear/cazrpoam1.html i've used this amp for about a year and a half and it is the best amp i've ever owned (over 6 different amps) and one of the best amps that i have ever heard all of the above of course is IMHO and others may offer other suggestions.... but i know that this amp would make your LaScalas sing!! good luck in your amp quest!

(and every newer CD player was better than the previous one) here are several models of "changers" that the Absolute Sound magazine picked as best products in their respective price ranges for high-resolution digital sources Sony DVP-NC685V - 5 disc DVD/CD/SACD changer - (recommended earlier in this thread) - MSRP $250 http://www.soundandvisionmag.com/article.asp?section_id=3&article_id=632&page_number=1 "With all due respect to the venerable CD, I began my listening session by popping in the six-channel SACD version of Shania Twains Up! The catchy title tune features Twains honey-sweet vocals in the front left/right channels along with guitars, piano, synthesizer, drums, and bass guitar. Guitars, piano, and synthesizer also appear in the surround channels, with just a dash of reverberated vocals. The taut kick drum and bass guitar get the subwoofer channel all to themselves, which creates a rock-solid foundation. In the center channel theres only a touch of reverberated vocals and the piano track, but the mix makes great use of spatial cues, adding to the song but not drawing attention to itself. Overall sound quality on the Sony player was first-rate, with the kind of clarity that youd expect from a pop recording on SACD. The synthesizer and guitars in particular really jumped out of the surround speakers with terrific punch and aggressive energy, without ever sounding harsh." Sony DVP-CX985V - 400 disc CD/SACD changer - MSRP $400 http://www.epinions.com/content_115454348932 "The sound quality of CDs and DVD depends on the receiver and speakers you use, provided you employ the changers optical or coaxial digital audio connection. If you use the analog 5.1 out (which you have to do for SACD), the sound is excellent (if your receiver and speakers are good enough). The changer even provides bass management for all formats it plays, including SACD!" Integra DPC-8.5 - 5 disc DVD/CD/SACD/DVD-audio changer - MSRP $700 http://www.hometheaterhifi.com/volume_11_3/integra-dpc-85-universal-player-9-2004.html "Auditioning the Integra has really whet my appetite for DVD-A and SACD. If a $700 multi-format player can go this far with those formats, I can only imagine what a far more costly player can do with them. I now understand what Secrets Editor John Johnson meant when he sent me an e-mail stating that the $8,000 one-piece Classé SACD player blows my transport/Theta Redbook CD combo out of the water. (At least, until the Theta Gen VIII acquires the ability to decode SACD bitstreams - Ed.) The Integras strength in audio lies with reproducing high-resolution formats, especially SACD. It gives enough of a sense of these formats potential to deliver a satisfying listening experience. Those accustomed to live performance, especially of orchestral and choral music, will note a lack of bass and treble extension. Equally apparent is that the Integras enviable degree of clarity, depth and air on high resolution formats are achieved in part by eliminating detail that might otherwise muddy up the image. What you end up with may have an overly quiet, slightly sterile sound that will never be mistaken for the real thing. But taken on its own terms, it is also quite pleasing. (My own experiences with SACD are that the detail is there, but just not so much in your face. And, the bottom line is that a high end CD setup can still outperform a modest priced DVD-A/SACD setup, which is why I asked Jason to review this player. Nevertheless, DVD-A and SACD are big steps forward, keeping the overall price the same - Ed.) The Integra DPC-8.5 offers a degree of musicality that makes it highly competitive. If memory of the now-discontinued $299 Sony SCD-CE775 5-disc SACD/DVD-V changer (auditioned in a very different system) serves me right, the Integra represents a giant step forward. It also sounds a lot better on SACD and DVD-A than the $499 NAD 541i did on HDCD-encoded CD. For $700, the Integra DPC-8.5 is a noteworthy achievement. And thats simply in two-channel audio. When you add in such bonuses as DVD-As video options, multi-channel DVD-A and SACD, along with DVD-V, you realize just how far weve come in a remarkably short time." perhaps you need to get out more btw - i am not an "audiophool" and never plan to be one

it does all come down to your style of listening if you listen to compressed music with little dynamic range, a low powered amp might very well work in your situation but try to use the same low powered amp with very dynamic music/soundtracks and you will experience more than a few problems dynamic soundtracks/music can easily contain fast transient peaks that require 10 to 20 times the average power output during the rest of the program... listening to your music at 1 watt (for example) as your average level.... the peaks can easily reach 20 watts or more no amp is perfect.... but an amp that cannot handle extreme dynamic peaks is one that would not be welcome in my system and for SPL calculators.... the following is one that takes room boundary effects, number of speakers, and listening position distance.... http://www.myhometheater.homestead.com/splcalculator.html
