Yaqin tube amps: any further thoughts?

[Hearingaid]

Sorry it has taken me awhile to get back to this forum. I think we all know the story, Kids, Wife, life.

First let me say I was a die hard transistor guy. I have right now all Classe Delta series components.

So I ventured into the tube world with not much knowledge, but have been educating myself over the net.. I have found out not to take myself to seriously having been in this hobby for at least 20+ yrs. I do take my music serious.

Anyhow I am not a professional reviewer of any sort so please for give me for any mistakes or misunderstandings. I will be as honest and subjective as I can. Just stating what I hear and what music I listened to

So here we go.

First off the packaging and shipping carton (which was double boxed) was out standing.

Instructions were very good all was in order,clear English,even some info on biasing(good for us newbies) I would still check out the internet for a video on biasing just for comfort sake.
After unpacking the quality is quite apparent. Solid heavy construction along with fairly decent power cord as well as nice binding posts they look like WBT? Seem to be very good quality.

Now lets plug it in. Everything. Does what it should, tubes glowing (El34's) along with 6J1. Little blue glow by volume control.

I hooked to my old Sony 999es DVD,super audio cd player. Using transparent music link super RCA interconnects. That's pretty much it for components. I also am using Kimber cable 12tc and WBT banana plugs.
The speakers are DC10audio Berlin mini monitors.

All my listening was done in Ultra Linear mode. Did not have time to do A/B comparisons between the two modes.

I let everything warm up for 5-10 mins. The first song I played was from Diana Krall Love Scenes track 4 "Miss You So". My first thought were how come at quater volume it seems a lot louder than my Delta serries CA2200 amp. ( I've read that tube amps have more current which gives it more volume) this is not what I know only what I've read.

Next I skipped to track 1 "All or Nothing at All" of the same album.
Something still seemed amiss. Volume was there but it needed something. It sounded hollow, but I couldn't quite put my finger on it.


Thats when I thought I should let the Yaqin run for awhile and see if it could get better. So I popped in Holly Cole collection Vol.1 and let repeat for about 14 hours.

After the 14 hour burn in or whatever we want to call it. I played Dire Starits the very best of track 3 "Romeo and Juliet" this amp did not let me down keeping the volume between 1/4 and 1/2 I could really not believe this. The vocals were realistic the bass seemed fast and open. Time to switch to track 5 "Private Investigations". All the sound is there I could hear the glass breaking in the back ground. The breathing the creaking of door and when the bass came in it was not lacking or at least I did not feel the need to turn it up. The little Yaqin seemed to be in good control all musical nuances.

Next I played the cd Midnight oil's "Blue Sky Mine " track 9 "One Country" this time I was more than surprised at how this little amp made me feel. The distinctive voice of Petter Garrett was crisp and clean. The bass and guitars were upfront and clear. I next skipped to track 10 "Anartica" I can not lie I pushed the amp on this song I put it to 3/4 or more. Expecting the bottom to fall out or the unit to basically shut down. Not gonna happen. Everything once again was it should be the haunting voice of Mr. Garrett was, well haunting! When he cuts in with the phrase " one place left in this world"

I am very pleased with the Yaqin ms20-l. I think from experience the little amp needs some time to warm up. I have been running it now for about 30-40 hours. It seems to be getting better every hour. Oh yes I did replay the Dian Krall cd. Much, much better atfter the 14 hours burn in. I did not think that it would make so much differance, but take your time and let this amp do its thing. For it will not disappoint and I have to say I am hooked tubes.

Just let me say in retrospect I love my Classe gear
It can produce pure magic and I love it.

I just have to say for anyone looking to get into tubes for a budget price before they make a move into the higher end markets. You should at least give this a serious listen. Well that's it for now. I would like to thank Mr Song Gao very friendly fast service. He has an e-bay site look it up he is in Ontario, Canada.

I also have ordered a shanling cd3000 top loading player. We will see how these mate together.

Thanks for reading. I would love your feed back. Thanks.

Thanks for your comments, Hearingaid, and welcome to AR forums.

It would not be unusual for tube amp (or any amp) to need 100+ hours before it sounds its best.

This thread is a little outdated, but I want to add a little to it.

I own the Yaqin 13S which is an update of the 10T. Right from the beginning it sounded better than most ss amps I've listened to, but I discovered that with the right tubes, this amp really shines way above the norm. I use Svetlana winged =C= for power and Full Music for preamp duty. The result is a truly holographic soundstage with solid images throughout. The best way to describe the sound is that it sounds real, real instruments and real people populating a 3D space.

Only twice have I heard soundstaging and imaging this good and that was with relatively very expensive SS gear. I think the SS gear in those systems produced a bit more air between instruments than the Yaqin, but the Yaqin sounds better is some ways too.

To make a long story short, it doesn't get "much" better than this. I realize too that I might have just gotten lucky and the synergies just fell into place with my system.
