What HiFi amplifier? What type to choose?

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.

@@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

[@PearlAcoustics]

@@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

[@humanitech]

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

[@matthewtaylor7355]

I purchased a 600gbp 300b amp from China sounds xcellent... The price was the clincher... The mark ups on audio as soon as it hits the UK is laffable.. Guitar shops r usually cheaper than hi fi shops for repairs... Their no crap approach is good.. And they sell very cheap interconects £3.99

[@Csnumber1]

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!!!

[@carlitomelon4610]

@aulker62 Thats 87db @ 1 metre from 1 Sebelius speaker....most of us listen at closer to 3 metres away which needs 3w for 87db for this speaker. Nevertheless the point is that you hardly ever use more than 10 Watts ;-)

A great explanation that makes things so simple, in a pleasant way that makes us deepen more in the magic of sound and in the world of amplifiers where there will always be contradictions in search of perfection. Listening to someone with so much knowledge and experience I can’t resist asking their opinion about the monoblocks " Bel Canto SET-80" that I’m thinking of acquiring. I will continue to absorb and delight myself and his wonderful videos, which reach all over the world. In this case to Portugal. Thank you

[@PearlAcoustics]

Thank you Antonio!

[@osbert43]

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.

[@PearlAcoustics]

Thank you for your kind appreciation. Agreed, some manufacturers were making very good output transformers. But even that technology has advanced in recent decades. But that does not necessarily mean ’sounding better’. Feel to contact us via our website to see if a listening session can be arranged. Enjoy your music and wonderful amplifier.

Hello Mr. Lovegrove, a real fine job you’re doing and “…..you took the words right out of my mouth…..” ;-) ! Congrats that’s pure audiophile realism and I wish that there would be more people like you in this business. ‘Cause there not much people which know that for example 0.5 Watt even on a 85 dB speaker means room volume.

A danish hi-fi magazine once made a test together with the danish Quad import whether they could hear the difference between a Quad system and a selected high end system. 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.

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.

[@ericb9426]

Another great talk from a UK perspective. Was waiting for you to get to damping factor which you did. I think the hard rock music of the late 60s/early 70s was a big push toward the AB amps.

[@rolandlickert2904]

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 think nature has turned my top end filter to max.

[@PearlAcoustics]

Thanks for your kind comment. The lack of treble could be a bit of both? Aging capacitors and or tweeters (most likely tweeters) that can easily be replaced and aging ears, that prove a more challenging reality (although our brains are very good at compensating).
