Yamaha A-S2000 новое слово в стерео от этой фирмы?

Про виртуальный рынок - так, там и товары свежее и интереснее, чем в реальных магазинах. А чтобы не облажаться, и существует инет. Посидишь денек над мучимым вопросом, будешь ой, как эрудированный! А потестить можно и в маг. съездить, да только там не всегда "горячее" есть, скорее старъе. Я перед покупкой Ямахи 2000, с другом возмамерился ее прослушать - болт!
Еще недели две назад, нигде не было. Первым в очередь на привоз записался, где только можно было. Сейчас обладаю, и хоть не слушал до покупки, чичуть от непроверенного действия не раскаиваюсь.

Подытожим:
Это усилитель и он усиливает сигнал. Сайт Миллераудиоресёч, проводивший тест, признал усилитель не прошедшим его по одному параметру: "зависимость искажений от частоты в децибеллах". Почему тогда он прошел зависимость искажений от частоты в процентах - фиг его знает.
Короче, все эти цифры никак не отражаются на звучании, а вот о звучании нам сейчас расскажут Дмитрий Волк и Vinyl Recruit.

Очень классный аппарат (это про Yamaha 2000 усилитель), взял с ним СД Ямаха 2000, балансный кабель Chord anthem и акустические Би-вайринговые провода Qed silver anniversary xt, сетевой фильтр Furutech e-tp80e и такие же силовые кабели Фурутеч. Хотелось собрать сразу, что то приличное, адекватное стоимости усилителя и сидюка. Надеялся на хороший результат, очень приятно, что не ошибся и даже результат превзошел ожидание - пробирает до дрожи и хочется слушать и слушать. Про аппараты - качество сборки и отделка - высшее!   Акустику взял Wharfedale evo 2-50 http://www.wharfedale-audio.ru/catalog/detail.php?qid=18358&gid=120171 в черном лаке, понравились внешне на рекламной картинке в журнале "What hi*fi?" . Доволен до усра..и. По моему, Ямаха вполне подружилась с Английскими проводами и акустикой. Великолепно играют вокальные партии, электронную музыку, классику, джаз. Детальность и звуковой образ офигенный, никакого окраса. Рок не пробовал, не очень люблю.
По поводу сравнения - у меня в другой комнате стоит д/к с проектором Панасоник и все такое (до сих пор доволен, собирал лет пять назад) но основной упор тогда был на видео. Сравниваю с аппаратурой друга, у него дорого - колонки Вест лейк и все под стать им (правда у него плохая, для звука, комната), так он когда услышал, как звучит Ямаха..., расстроился бедный, потому, что в деньгах, у него аппараты на порядок лучше.
Еще, я, в свете надвинувшейся эры Хай-Ди, взя ресивер Ямаха 3800 и к нему..., если интересно напишу и про это, т.к. Ямаху усилитель воткнул в Ямаху ресивер, ну и т.д...
