    It's nice this channel is introducing and reviewing entry level products.
    For cables, I also like the ones made by World Best Cables on Amazon. They are a step up in isolating noise and making sure grounding is done correctly.

    The thing you have to remember with Tubes is they were often measured as TRUE RMS power, not peak power.
    a 5Watt rated Tube amp can, and often will, out perfrom a 50watt peak rated modern solid state amp. A lot of Guitar amps still have tube output stages and they deliver plenty of sound output. Don't get too focused on watts, it all depends on the way they are measured.

    Spikes directly couple the item in question to the floor, generally not a desirable effect. Isolation pads are almost always a better option, provided they are well-executed.
    Your speaker wire looks thinner than what they used to wind that toroidal transformer, rather undersized.
    That amp looks like a great build for the money.

    Greetings! I'm running the Douk Audio Pro G3 with BT amp, pushing a couple of Boston CR75 speakers. Okay, here's my questions: I'm wondering how much better this amp will sound, and I'm especially concerned that it does not have bass or treble controls. It also does not have BT, but I can add that. I'm really interested in good, sweet sound, and so if you have a recommendation in the compact amp department, that would be great. Without bass and treble controls, I'm concerned I won't be able to tame the bass or highs if needed. Your thoughts?

    • @2DudesAudio
      @2DudesAudio  4 года назад +1

      This amp is fantastic to replace yours, the only thing like you stated is that you definitely would benefit from a solid pre amp with tone controls if you wanted. This amp has a warmer sound than typical solid state comparators. Kinda reminds me of the sound a GE 5654 tube. Warm mids. Soft highs. Full bass. But it is solid state after all so dont expect it to be as obvious of a sound change compared to tube rolling.

      Cladvik that's a different Amp by a different manufacturer on Ali express. There are several very similar Amps to the Fosi Audio HD-A1 in black or gold from other manufacturers based on the same design. But you don't know the quality as little to no reviews of them. Some of the components in them are different using cheaper capacitors, transformer etc.
      At least with the Fosi Audio HD-A1 it has has had quite a few reviews on Amazon, the Fosi Audio Web Store and this RUclips video. Most of the reviews very positive, a very good performing stereo amp for a reasonable price.
      You are better off paying a few pounds/bucks more knowing that you are getting a genuine Fosi Audio HD-A1. Rather than a cheaper Amp which looks almost the same but could likely be inferior sound bad with cheaper components used inside.

  • @YesICanHearIt

    Dude those speaker wires are not shielded. I've not heard of anyone using shielded speaker wires. I've seen some sold that are twisted (making a twisted pair) which might help if the wires are near a leaky transformer or other AC magnetic field. You can twist your own but it's hard to keep a good twist. Otherwise, nice video!

    I tried this amp with a couple of dacs, one using CS4398 and another AK4490. While it is warmer sounding than other amps, it tended to veil the sound and was far less resolving than an amp I compared and kept, an Aiyima A-04. So it affected the performance of the dacs in a negative way, IMO. For the price it's fine, well built and if you like the sound, great. I would have kept it if it were more resolving with midrange and highs but keeping smoothness rather than veiling the sound, smoothing over the layers within music which are there. The Aiyima sounded better overall "to me" and allowed the dacs to shine in comparison. So I guess the Fosi amp held the dacs back from their potential, IMO.
    Also the Fosi hummed a bit and got significantly warmer going from 8 to 6 ohm speakers. Not sure if it could really handle 2 to 4 ohm loads as it states.

    • @C--A
      @C--A 4 года назад +2

      The Aiyima A-04 is a cheap class D amp with average specs and high THD. The Fosi Audio HD-A1 is class AB and has good specs and quite low THD.
      Its a much better Amplifier spec wise and sound quality wise. The online reviews and two RUclips reviews back this up.

      @@2DudesAudio I don't think I did as I tried three, I wanted two for myself and I am not saying they were bad units although one got quite hot in comparison to the other two so sent back for that reason.
      I could hear the hum which FOSI said was normal and from 4 to 5 feet away which I would have to accept if used on desktop. BTW, I did rate the unit a 4 out of 5 as it is well built and decent while leaving room for FOSI to improve...maybe they did. I was surprised however that an inexpensive class D could be more transparent with sources, dacs, cds...the only way to find out is to get one and review it if you care to do that. I chose the Aiyima A04 which also received good feedback from users.
      As one or two others stated, there is room to improve. But for a couple of hundred, you can't argue with the price which makes it very competitive in the class AB market. Although if you purchase these in quantity overseas, you can get them for half the price unit wise. So, every product from every brand has to have a good degree of markup...there it is.
      How about a comparison with a similarly priced Emotiva? As a reviewer, you are going to get people's opinions, experiences and such and hopefully everyone stays civil. It's part of the hobby and part of reviewing. Invite people to leave opinions on their own experiences. It makes it more useful rather than appearing to be a fan club. Nothing against FOSI, I think what they are doing is great and should be encouraged to continue. The Chinese manufacturers are producing quality at an affordable price...keep it up. Cheers.

    The SMSL M100 is a great little DAC under $100 but don't buy it based on the high sample rates they tout, its mostly marketing BS. Most mainstream music at best is 16bit/44.1khz and a lot of it because of the loudness wars is much less. Very little music is actually recorded with audiophile playback in mind. A lot of 24bit audio is just remastered or upsampled 16bit and 32bit audio is pure nonsense. On the other hand great video, I got a Fosi HD-A1 on the way.

      Also you should look into Tidal. Full MQA support up to 32 bit 318khz. So it's very useful. Just cause you havent heard it or seen it doesnt mean it's not out there.

      @@2DudesAudio - I had Tidal for a while year or so ago but rarely used it, I have Spotifiy now and really don't use it either, just keep it for some reviews I have planned. I have hundreds of gigs of WAV & FLAC music at home on my music PC so that gives me plenty of selection. I have plans to try some MQA content in the future, but right now the premium DAC cost and only source being Tidal doesn't work for me. I've done a good bit of reading about MQA and many agree its supposedly better sound mostly has to do with its remastering process than high sample rate. I lot of MQA is just upsampled and remastered from original analog sources like studio tape which is less than CD quality. But like anything else if someone likes it that much then go ahead and enjoy. The standard redbook 16bit/44.1 with dithering is capable of 120db of dynamic range and 20khz which means with a good audio system it should be completely transparent to any human deliving nearly perfect audio playback. The answer isn't hi sample rates its just better recording, mixing, and mastering.
