What HiFi amplifier? What type to choose?

Тәжірибелік нұсқаулар және стиль

Ever wondered what the difference is between Class 'A', Class 'AB' and Class 'D' HiFi amplifiers? What's the difference in their sound and what should you look for when choosing an amplifier for your system? Also (from 38:17) Harley Lovegrove, the technical director of the loudspeaker company 'Pearl acoustics Ltd.' talks about how sound is converted into electricity and how that is amplified so that the loudspeaker's drive cone can convert the electricity back into sound. The video is interspersed with clips from the charity work for young classical musicians that Pearl Acoustics invests a sizeable proportion of its profits in.
(The intro. and outro music is 'Philia' written and performed by Stefan Meylaers, and taken from his piano suite 'The Four Loves').
Editorial 'errata' note: During this video I refer to 'Push-Pull amplifiers and attribute them to Class A-B amplifiers. This is not always true, and in fact I failed to mention that 'Push-Pull designs can be used in Class 'A', 'AB' or 'B' design. For example; in some Class 'A' amplifier designs, pairs or multiples of transistors (or Tubes) are configured in such a way that they start off in Pure Class A but switch to supplying their current in both directions (push-pull), once a certain output current is used. Sorry if any confusion was created. Thanks to those who took the time to comment on this topic.

    There are so many self-proclaimed experts that it is so refreshing to listen to these clear, articulate lectures delivered by a a classical recording producer, and they chime so well with my own experience, not as an "audiophile" but as a music-lover.. Thanks.

    @@PearlAcoustics Many thanks for this great video ! , making it very nice explained and intuitive. I have a question and I hope you can answer, Just got a very rare power amp ADCOM GFA555 MK2 Nelson Pass design, bought it from the US and it was new and never opened from the original box, so it was in the original manufacturer box for more then 20-25 years, all I can say It is sound amazing, it is connected in my setup to used ADCOM GFP565 pre amp , and now I explore very nice and chip tube pre amp Fosi audio tube P1 with GE5654 tubes by Riverstone audio the sound is incredible. So do you think should I replaced the electrolytic caps inside the power amp ? I have removed the top cover and the internals of course looks as new and I have the Bias been checked by me and is as specs . Thanks in advance

    @@RanTausi Hi. What I am about to tell you is my ‘opinion’. And as such, do not want to proclaim myself as an expert, so please take it as that - an opinion. My rule is, if it sounds good, and there’s no buzzing, hissing or excessive cone movement when idle, then leave it alone and simply enjoy it. 20-25 years is not old for an amplifier of that quality. In the old days (pre-1980’s) - people used oil filled capacitors and they definitely had a habit of breaking down. But todays modern components (and I include amps of the last 20 years) are generally way better made. Do enjoy it and look after it. Best wishes - Harley

    Thank you so much for this video and the others I have viewed thus far. I’m nearing 60 and been into music listening equipment for many years. It took me many years to find the right amplifier for my Quad ESL57s and only after living with the others (Quad ll’s, 303, Leak even a pair of Altec Lansing 1569A mono blocks) before hearing it all come right with the Radford STA25. My point is the exercise of finding the right amplifier can be a journey of many years of listening before you arrive at your musical bliss. Again, wonderful videos but they do have me wanting to hear those Sibelius speakers. They look beautiful. One point I might add is that although internal components have generally improved, I’d argue that many output transformers of yesteryear are equal to those of today.

    Good evening 🌺 from my humble country ❤️ the Philippines Mr Lovegrove... This is my second video for the day from Pearl Acoustics. Very informative easy to understand explanation of the types of amplifiers. My son just bought a NAD C338 or 388 from his Christmas bonus. I just bought a can of electronic contact cleaner and the baffless for my Coral 6CX will be done by Friday next week. It's a 98dB coaxial drivers and I am excited about hooking it up with what I think is a good baffles sporting a similar rectangular port like your speaker 🔊, my favourite Sibelius speakers. My favourite Class A integrated amplifier is the Musical Fidelity A-1 or A1X. I heard a brand new one 20 years ago and I am hesitant to buy a second hand ✋ unit because of its price (they are kinda pricey considering they are used units and I don't know its history) and how hot they operate but since I got a lot of education from you sir, I don't think I will be using beyond 2w/chan for the kind of speakers I have. The 86dB Celestion 1 I have when I put them in a box similar to your Sibelius is around 93dB because it plays loudly at pleasant levels. I don't crank the volume that much. I just played a direct to disc LP and my neighbor in front hum the melodic right up when I plan to change the record so I put the same LP and spin it back. Just an update, I made a similar box like your nice Sibelius instead of making an adjustable port as warmly suggested by my carpenter. He needs the extra cash to take his wife out for a simple dinner and grocery for the holidays.

    Thanks for a very informative outline of amplifiers. We are all very lucky to have such a diversity of quality equipment to choose...to hopefully match the sound signatures that we personally want or would like to hear for our budgets. My favourite combination is to use a valve preamp and class d power amps. As class d power is very strong, neutral and highly efficient and then the tube pre allows (and can be further tuned) to provide a little more additional harmonic warmth and dimensionality and the sound can be further tweaked by rolling different tubes..which is fun. Sadly tube power amps for me are great but too expensive to run as good power tubes are often very expensive for the better ones. But you are right Chinese hifi gear is fab, often very well designed and built and very affordable...the only one small caveat regards warranties, service and support ..primarily due to location and logistical issues of course. But I have never had any issues or problems...after all many western brands are also made in China too. Thanks again and keep up the great work

They could detect the difference but it was very difficult. Regarding design and quality of components, the Jean Hiraga “Le Monstre” was famous for it’s ability to play with almost every loudspeaker. It had so much power reserve that it continued playing long after the power was dis-connected.

    Excellent video. I enjoy the long format. As you said, second hand amps should be tested on cheap speakers, PLUS be left running for hours to prove thermal stability.

    You would love both the sound and exceptional build quality of the Yamaha AS-801 Integrated Amplifier!! I’ve auditioned quite a few of Amps and landed on this A/B Amplifier, rated at 100 High Current amps, this amp which can be had for $699.00 on sale, (originally priced at 899.00) sounds as close to that smooth tube sound for the money as anything. Mated with a pair of KLH Kendall Towers rated a 96db, the ease at which the pair produces recorded music is never fatiguing and just a joy to listen to for hours. I owned the wonderful sounding Luxman LV105u, Tube Integrated amplifier, which I lost, well really stolen from a dealer I took to for servicing 15 years ago. It was such a wonderful sounding amplifier and beautifully designed. Nothing in its price range, I paid 1200 for it new, that I purchased ever matched its warm signature…..until the Yamaha! I haven’t heard the Heigl, but it’s been a delight to have at my home, which is a relatively small space….perfect for music listening!! Another great video….Loved it!!!

    I'm happy with my NAD C388 its future orientated because it can up-grated by adding MDC Modules into the amp such as BluOS (streaming etc) for an affordable price meaning you don't need a separate streamer that cost much more.I did had all types of amps during the last 50 years and all sounded great(including a QUAD).However today the technology move much faster therefore I choose an integrated amp that can keep up when new technology is available.Beside that I always liked fast and dynamic amps.

I have had a great deal of fun upgrading amplifiers with much better modern components, including electrolytic caps, wire wound resistors, speaker binding posts and even RCA sockets. The resulting improvements are clearly audible and I have no doubt these amps will go on for many years. I look forward to more of your videos.

    Great video. I listen to Zu speakers which like the Sibelius have no crossover. There is a full range 10 inch driver and a super tweeter that handles harmonIcs above 12k. The tweeter is protected with Clarity cap to prevent damage. I’m driving them with a Naim Nait 5Si integrated amp. I am considering moving to Sibelius. I like your approach to audio.

Go to any tradeshow and it's old, grey men wall to wall, and that explains the type of music 'audiophiles' always seem to listen to and therefore the types of systems they rave about. I'd be very interested to listen to the views of someone with a more electic range of music interests.

    @@mediapc4747 I listen to a lot of different genres myself. What do you imagine is different? I mean different genres, Death metal, EDM, Salsa, Punk, Brit Pop... etc. I personally wouldn't use a Sibelius. I much prefer the clarity of a 3-way. A good 3 Way can sound very coherent. But at the end of things, if we listen to death metal on a monophonic Bluetooth speaker, why a Sibelius should be discarded? At the end one would end up enjoying the music, quite frankly.

    Most welcome to hear from a true professional on what is otherwise 'Hi-Fi bs'. I remember building a PA design by John Linsley Hood in the early '70s which provided up to 25W in Class AB but with adjustable pre-set quiescent current in the output pair which varied the proportion of Class A amplification - see Wireless World Magazine of July 1970. Its specification seems ideally suited to your definition of 'it's the first watt which counts'. Anyway, my recollection is that the amplifier sounded so good that my friends came round just to have a listen and one at least counted it as a reference standard! Sadly, the transistor pair specified was fairly frail and has long since been discontinued. Modern replacements may not be up to the mark.

    Thanks for your kind words. Your amp sounded wonderful, I bet. However, I would not write off modern transistors, there are some really incredible products out there! Remember, when you built your amp, solid state transistors were still rather new technology 😉 time to rebuild it!

    @@PearlAcoustics In a way, I have done so. My current equipment includes amplifiers with Power MOSFET output stages. I like to think of them operating like potentiometers where the speaker joins to the wiper which moves up and down (resistively speaking) at audio frequencies! Half way to tubes, don't you think? Changing subject slightly, there's a lot going for sensitive, wide range single speakers as in your design. If money has to be spent anywhere, then it is the speaker you need to address for quality of experience. If you have to revert to a multi speaker approach, there was once a Yamaha design which used electroststics for the mid/high range and a massive, high density slab of polystyrene (measured in square feet) for bass. It sounded pretty good. Brings a whole new world of meaning to 'plane wave'.
