However, the HA-02 really makes my DT990' 05 and K501 sing I never really enjoy these two headphones as they sound "boring" to my ears, very enjoyable/musical, full-bodied and refined.

Thank's shiosai,

It seems that, as others have also reported, there is a special synergy between Edition 9 and the RPX-33. The only problem is that I have a feeling that the HA-02 is precisely what my HP-DX1000 needs to really shine. Well, well, I can't buy two amps (at least not according to what I've been told by my wife

) so I'll prioritize the performance with my Edition 9's.

Unfortunately it didn't cure the hum so I switched back to the DHA3000.

What you're describing sounds a little like an issue I ran into with one of the 408A tubes supplied by Yamamoto. It is very microphonic and occasionally upon powering up creates some evil hum in whatever channel it is assigned to, currently the right. Powering down, waiting, then powering back up again typically eliminates the hum. One bizarre thing I've noticed is that sometimes I get the slight hum (in both channels) others have mentioned yet at other times the Yammy is essentially dead quiet. I'm not sure what to make of that. I am waiting for Brian at Venus to ship out another set of tubes.

Superpredator: That's interesting. It's pretty much what I experience myself!

I bought some spare WE408A's so I'll bring some home and try replacing them the next time I get bad hum.

This is what prompted me to buy several 408A's. I had to play around a bit before finding a set that had no microphonics in the HA-02. It was worth the effort, though.

i think i read earlier in this thread that one cannot really tube roll with the 408As...that the differences are very minor. is this true? or have some of you found 408As that make a noticeable difference?

Ancient Chinese Secret

- kidding aside, just make sure that I make regular visits to select H-Fi shoppes in town. There are a couple of folks that I've run into since living here whom, IMO, have a good ear for picking out gems that otherwise get lost in the musical wilderness.

When ordering an Almarro A318B for my other office earlier this week, the chaps there introduced me to another gem entitled "Hearing the song - Listening the Silence" (TopMusic TM-SACD9011.2). Story goes that this TopMusic rep was so taken by the Almarro when hearing it in Hong Kong, that he remixed some of his favourite Leslie Ritter (folk singer) & Scott Petito (studio musician) tracks via mostly Almarro equipment thinking he could bring it to another level sound/recording wise. Apparently, the Ritter/Petito duo (hailing from the Hudson Valley - me olde stompin' grounds before coming to HK) are renown for some really unique full bodied folksy music.

Well, not knowing what the original sounded like and having only listened to the CD layer, I can tell you this is one beautiful collection and not just another sultry female voice retread. You can check it out here . . . http://www.topmusic.com/sacd9011.2.htm. Will probably get a chance to hear it over the Yammy tonight and am expecting great things.

Cheers,
Garry

Agreed - I should think that this CD would be tailor made for the K1Ks . . . methinks you'll be glad you did.

Cheers,
Garry

I haven't noticed a huge difference in sound. (Hey, I'm 62 years old. I'm lucky to hear at all.) However, I did have to play around with tubes to eliminate all tube noise. My amp now has a dead quiet background.

Interesting “Drift” in the thread- Music. I think it speaks highly of the HA-02 and it’s ability to present the music.

Interesting and profound observation . . .

Llistening now to the new CD referred to above, I'm thinking to myself "wow, this is real music" and then caught your post. Couldn't have put it better.

Cheers,
Garry

PS - This new CD sounds just fab via the Yammy - if one fancies this genre, I think you'd be in for a real treat.

This is step two if the replacement tubes don't do the trick.

Can you post some info on where you are finding the 408A tubes?? ebay sellers I'm guessing? (Which kind of makes me shutter these days.)

 

[slwiser]

http://www.sphere.bc.ca/test/tubes-we.html#catalog

This is one place that I have found. No endorsement though only because I have no experience with them. I found this site after I purchased a set of five off ebay for myself in anticipation.

Note that the description of the amp that I got suggests that a balanced pair should be used and that the supplier will provide these when needed.

This is where I bought my stash of 408A's. Good service and very friendly. The shipping costs are a bit high, though.

Yamamoto HA-02 is in the house....

Initial impression is that this amp has an ability to imbue whatever emotion is in the music right into my heart, beautiful music out of the Ultrasone Edition 9s.
