Be patient with the trends-ta10, It sounds very thin and light in the first week. Mine took about 3 weeks to really sound good.

Anyone who have modified it with a subwoofer out, so you can use subwoofers with it?

Any suggestion what parts i should use if i want to modify it with sub out.

Best Regards David

Yes I'm gonna give them some time in my system, although at the moment I'm only willing to go back to my Hiraga and my 300B SET's. The Trends are getting a bit on my nerves. Funnt thing though is that my girlfriend askes me all day to get the volume of the music down while I'm playing not at all as loud as I normal do, it's just that their is something very nervous in the sound wich give you listening fatigue after a couple of minutes. Sounds just like cheap solid state with lots amount of overall feedback and incapable power supplies.

Maybe the Trends don't like my 6 meters of CAT5 speaker cable. Have to try to bring them closer to he speakers but at the moment I don't have any long interconnects. Think I'm going to make some cheap ones out of ordinaary coax cable just to try if this helps.

Has anyone looked at the output filters in the Trends ? Seems like a copy of the TA2024 evaluation board with the addition of some extra 10nF caps on the output. Anyone tried some better quality caps on the output filter ? Would be hard to find I guess, size is an important issue here.

Would shielding the output filters with Stillpoints ERS sheets be sufficient (happen to have a spare sheet lying around) or would an additional copper shield be better ? I'm thinking of shielding the input caps as well, trying to ged rid of that anoying nervous sound.

All I can tell right now is that out of the box, brand new these things have nothing to do with high-end audio what so ever. But I'm not giving up so don't draw any fast conclusion out of my observations, yet.

Well, your subwoofers would have to be quite sensitive to take advantage of the Trends. You do not have to do anything special. Either they will work or they won't.

I have made Pano's Rf Shield and think that I have got an amp with a much more silence background. Turning to battery power had about the same effect. Nothing to pinpoint but everything much calmer. I think both tweaks are worthwihle. Otherwhise the ver 1.1 is a very competent amp.

Sjef,

Very interesting ! You seem to be helplessly guarded by your girlfriend to whatever she wants. Be glaad !

However there is no biased response from the Trends Ta-10 so
if you prefer tube sound like the Hiraga or 300B-sets thats it.
Nothing wrong with the Trends.

6 meters of diy cat 5 speaker cable? wow, I thought 3 meters was the maximum recommended. How long did that take you to braid? I actually have some cat 5 on order now for that purpose.

I second the suggestion for battery power if you have a chance to try it out; it turns down the fatigue and adds a little more body for me. Going back to the included power supply gets on my nerves after listening to battery power for long periods now. The hiraga and 300b amps are very well regarded, so I don't doubt that you may like them better. Maybe your equipment or ears just don't synergize with the trends.

Got to stand up and be counted! Seriously though, you under estimate this little guy. Pano. is too modest to speak up but I will since I have been the proud owner of the "shep"1" for a while now. What's that? A fully revisited version, la P. This is not a good amp this is a great one. Transparent, detailed, sweet, whatever you want. I have heard the Hiraga in question, or at least one from that era. It isn't even close to the Trends in bass, treble or resolution. I would be happy with it forever but for the low power issue which has to do with my speakers, and is no reflexion on the amp.

I'm using 75cm long bulk anti-cables, very cheap ... but really really good, I tried Vdhull, Audioquest, Sonic link and Nordost but they all added something bad to the sound.

It's about 1,25 dollars per foot!

I also use their IC's

Once I find time, I would also like to do some mods for my trends, But I find it calm enough as it is, just the right balance.

Pano's RF field looks very good, but I would not know where to find the needed stuff for that.

(still have that skynet 8080 SMPS but not using it)

Today I have made some first simple mods to one of the Trends. I have glued some "Sirex" damping sheets to the bottom and the top of the enclosure and also added some Stillpoints ERS sheets to the top, the bottom and wrapped some around the aircore inductors.

Compared to the unmodded unit things have really opened up, much much more detail, better dynamics, stiffer low/mids. The whole sound spectrum shifted a bit upwards though wich you might like or not, I thinks that's a little withdraw with this mod. It's still no competition for my other however but it's getting really better and it doesn't get on my nerves so much anymore (RFI ?). I think the rends does have a very serious RFI problem inside.

In the next days I will try to ad some kind of heatsink/Sirex damping and ERS shielding to the Tripath chip and the input caps as well.
After that I will have to experiment with the power supply and maybe the input caps.

Has anyone tried the difference between the Bennics and Auricaps ?
