    You brought up many points and I have little time right now, but after a couple of weeks researching T-amps I found quite a few posts on forums in which the poster rated the Charlize as the best or favourite, and only one person who preferred a different T-amp and Charlize was 2nd. So from what I saw Charlize is highly regarded wherever you look. I saw no negatives and that is the best sign Smiley since it doesn't take much to make people complain...

    To be fair, I did a lot of A/B testing this arvo (again) the top end of the little valve amp isn't too bad at all, and overall the sound is very good, but the T-amp just sounds cleaner and better tonal balance, and overall, and this is the big one, the T-amp just sounds more natural, more real, and this is where it wins big time (proviso - on my speakers). Also it wins by sounding good no matter what type of music, so I guess it wins on quite a few points. Yes I was shocked Jonas, absolutely. A little cheap energy-efficient amp putting out great sound. I have no doubt that Charlize will rock my little ebay baby to sleep.

    I have not liked SS amps in the past, I built a gainclone and it was good for SS but didn't cut it. So a "digital" amp was way out left field for me. Glad I had a little look Smiley

    hi jonas

    yes, we've come across customers who don't like charlize. also customers who don't like monica, beyonce, eva, sophia etc.

    it's a free country where you are!

    Hello Ian,

    yes you are so correct, it doesn't take "them" much to complain. (Or us for that matter Smiley Smiley )

    To be honest, Only some Tube amps Tweaked to the maximum and some Nelson Pass SE designs we've tried can at all compete with the performance of a Charlize. (Those other amps are even more critical to choice of speakers)
    Tube amps aren't bad in comparison, but you are pointing out exactly what I've found, the clarity and realism takes a lot of efforts, matching and testing to get close to the Charlize kinda sound. Still if seriously never giving up, not needing much power, no budget, then you can to some peoples taste' pass Charlize's performance.. Smiley

    Hello yeo,

    It is hard to believe that some people does not like monica? May I ask what do they like?? HA HA do they like anything at all?
    Still YES monica has of course been improved seriously, so the earliest versions aren't as good as the last ones with
    mojo involved and so.
    So I can understand that some people could find some DAC's that can compete with the early versions of the monica's.
    That someone actually can DISLIKE monica as she is NOW, both monica3 and USB-Monica is hard for me to even believe.
    They must in some way have a system that can't handle good sound??
    I can't think of any other possibilities.
    That they dislike Charlize is also hard to believe, but that they could like something else a little bit better should be possible, in some cases.. Smiley

    Anyway, Free country, yes it is in many ways. It really is, most ways actually.
    I didn't quite understand your statement though, but that's OK.
    We are free, we live free, we are free to say what we want, we are free to go where we want, live where we want in the world, choose whatever to do, almost everything is a free choice to get or buy cause most have enough economical freedom, hospitals is free, all health care is more or less free, education of any kind is free for everyone,
    Yes My country is per definition relatively FREE in most ways.

    BTW, I hope you did not misunderstand the irony of some of the things I listed up there in the last post...  Wink Wink

    What I know now, is that Any day, any time it would take me some hours to setup a system anywhere around here,
    and everyone with they're hearing in working condition would be seriously Shocked.
    AND IT would be easy to do so with Monica and Charlize2, choice of speakers would vary with the size of the room, or if it was outside.

    I am very sure that most people that would have listened to that setup, would think there where something WRONG with they're own system when listening to it after that experience.
    If they are not the type of people that likes a stereo to sound like a whole football team trying to break trough a thin plastic or wood wall  Wink

    Interesting comment on the new amp, looks like a detour to the original intention of this thread.

    have you simulated the power supply with the duncam PSII. Have you seen the ripple riding on the B+!

    Has the tubecad been commissioned. How about the active load.

    No, I haven't done any mods at all to that amp, no simulations, haven't put the scope on B+, it is bone stock, except for reworking the PCB and adjusting the B+ and heater voltages to some happier levels (it runs on 220V not 240V so I have a transformer/line conditioner to achieve that). I was trying to rebuild a 1960 vintage amp with same 6P1 output tubes running pentode and like the DIYParadise simple EL84, to compare to the Mengyue. Eventually that will happen, just having a rest at the moment and enjoying the music... What I liked about the Mengyue was that it is pretty good straight out of the box, but to modify it for better performance I think it best to toss the PCB and rebuild it point to point for ease of trying different components. My plan was originally to try to build something better and then use those changes to modify the Mengyue, keeping the Mengyue as the reference and intact until I found something better.

    Been away too long so I don't know what is new and what is newer in here, but when I saw the pics of the small amp I made a notice that it sort of looks like a small amp I just have ordered from China (a Swede who lives there will bring loads of electronics to Sweden this summer). However it is a 6P1P SE-amp, propably with a SMPS PSUto make it small.
    I will send up some pics when I have it in my hand.

    Mentioned something about pics, here they are.




    Can anyone identufy the amp and maybe even give me a source of it. I have one ordered and paid for on its way in.

    I guess the amp is not very peculiar, but I will try to do some backwards engineering and give you some closeup shots as well.

    I am looking forward to this one. Grin

    Keep us posted soundbrigade, that is so cute!

    http://www.miniwatt.com.hk/products.html

    6J1 pentode driving a 6P1 beam tetrode. I like the 6P1, and they seem to be physically strong too. I wonder if they use a CCS on the anode of the 6J1? I say that because some of the reviews say it is very clean-sounding...sometimes I wonder that the better the valve amp becomes, the less it sounds like a valve amp!?      Yes looking forward to some inner pics!

    Looking forward to your impressions of this amp soundb. Not that I would buy one, I would get a Charlize before that, but the cute factor is almost irresistable...the missus is thinking about one for her PC fullrange 4" desktop speakers I built her...

    One pair of speakers for her, One pair of amplifier for you...

    Fair deal!!!....  Wink

    Better still, buy her the charlize to complete the set and you get the excuse to get a grown-up hifi set....  Roll Eyes
