Trudno to wytłumaczyć, bo oba wzmacniacze sa klasa dla siebie w polaczeniu z W5000. WA ma wiecej ciepla i po wymianie lamp inne rysowanie szczegołów. Oba polaczone interconnectem AT-RA5000.
HA5000 to skonczone rozwiazanie. "Pradu" wystarczy spokojnie. Problem z HA5000 jets taki, ze musisz miec transformator ja uzywam marki "CAPTORA" i to podobno audiofilskie rozwiazanie ale tak do konca nigdy nie bylem pewien czy to max mozliwosci teo wzmacniacza - zawsze to kolejne ogniwo. WA2 uzywam z PS Audio kablem zasilajacym a HA5000 "tylko" z normalnym sznurem.
Jesli angielski nie jest problemem to ponizej moje spostrzezenia :
It really comes to preference. With AT amp you feel like this is complete sound I mean it cannot be better and I have to admit imaging is really top of the line and most of the sound aspects are more than good but with WA2 you have a tube rolling at hand and this is like looking for the holy grail,if you know what I mean. You always hope that next tube combination will sound even better and so on so on ....
I\'m listening to new Katie Melua CD and in the last piece on this CD her voice in some moments is on the brink of being sibilant on AT amp but on WA2 I do not hear this the only thing that I hear is here voice that is definitely more intimate and emotional on WA2.I have to admit that on AT amp detail might be more pronounced but at the same time W5000 sound a bit hot in treble department. At least for me. It is really hard call as I think detail level might be the same but because different character treble in AT amp is more apparent. There is nothing wrong with AT amp and I do believe this is one of the best if not the best amp for W5000 but I just feel like W5000 are better matched with tubes . I cannot notice any harshness or sibilance when run through WA2 but with AT amp on some records this \'puzzles" me a bit. I\'m not so sure whether I like it or not. Maybe warm interconnects but I\'m not so sure about it. Another thing that bothers me with AT amp is the power cord. I\'m not so crazy about power cords but I do hear the difference and as AT is 100V unit I have to run it through "CAPTORA"adapter and thin normal power cords - I would really like to hear this amp on native 100V voltage just to be sure that this is the end for this amp. Why AT is not offering multivoltage units is just beyond me.
I\'ve been always about emotions in music and especially voices. I think W5000 reproduce voices very well and I found only 2 or 3 records where I can hear slight "nasal " coloration.
To represent it better for the voice only:
Katie Melua CD "The House" - track 12 The house.
on W5000 and AT amp sound believable but voice is a bit on the light side and a bit close of being sibilant,
on W5000 and WA2 same voice - pure joy and oh so crystal clear yet appealing, proper balance between detail and decay.
on HD650+SDv2 and WA2 she sounds like she gain couple of kilos. There is no veil but it is just a bit darker. It has it\'s own mood and I can understand why some people love Sennheiser house of sound , heck I like to listen to Norah Jones from time to time and I like HD650 for that task but for Katie Melua and other voices - especially in classical music this just does not work for me. I do not think that sound is like a lot bigger than W5000 or AKG but she just sound older and heavier in a way that I do not like. And more prominent less controlled synthetic bas. I hate new technologies but at least this CD comparing to the previous one is not bad from engineering point of view.
AKG501 (modded - flattered pads and blue tac sealing for more bas - this is version number 2 I think)and WA2 - very close to W5000 , voice very intimate , not sibilant at all. Maybe even a bit more 3D. Kind of pushed slightly towards the front of the soundstage.
AKG701 and WA2 - surprisingly close to AKG 501 - a bit less believable - a bit less body in the voice, good detail but voice sound kind of hollow? Not complete. Closer to being sibilant than AKG501.Less 3D too. Less apparent and merged with the soundstage. Like not being the leading actor and more like a part of the whole sound. This just confirms I should sell most of my cans and maybe get something new. This one will be leaving my shelf quite soon.
HD424 and WA2 just out of curiosity - not a surprise but same story as HD650 darker changed. not in the same league as HD650 that\'s for sure. But not like totally bad for such an old model. But this is 2000Ohm version and WA2 cranked at 12 o\'clock.
OK, this became a bit longer than I intended and it is close to 200 AM here in the country of tulips so time to bed."
