试试以下设定:
crossover: 60 Hz
speaker: large

也是新的落地音箱?那听一阵子先(给一个星期吧)。音箱线不要用太细的,大概14 awg或以上。低音不足就把音箱拉近靠墙。
再来就试pure direct mode (听音乐2.0)。

AV功放都是推灵敏度高的箱子,你的主音箱的参数是什么?好久不玩了已经忘了AV箱子的参数,好像4欧 92db-94db的箱子适合AV功放,你的箱子要是8欧83-89db左右灵敏度,AV功放就歇菜了,推不动。
倒反了。8 ohm 易推,4 ohm 难推。多数音箱所标的impedance是nominal impedance。8 ohm nominal 有时候会dip到6 ohm。很多AV receiver都不能推4 ohm nominal音箱。

http://en.wikipedia.org/wiki/Nominal_impedance

引用:
The impedance of a loudspeaker is not constant across all frequencies. In a typical loudspeaker the impedance will rise with increasing frequency from its dc value (see diagram) until it reaches a point of mechanical resonance. Following resonance, the impedance falls to a minimum and then begins to rise again.[20] Speakers are usually designed to operate at frequencies above their resonance, and for this reason it is the usual practice to define nominal impedance at this minimum and then round to the nearest standard value.[21][22] The ratio of the peak resonant frequency to the nominal impedance can be as much as 4:1.[23] It is, however, still perfectly possible for the low frequency impedance to actually be lower than the nominal impedance.[17] A given audio amplifier may not be capable of driving this low frequency impedance even though it is capable of driving the nominal impedance, a problem that can be solved either with the use of crossover filters or underrating the amplifier supplied.[24]

In the days of valves or vacuum tubes, most loudspeakers had a nominal impedance of 16 Ω. Valve outputs require an output transformer to match the very high output impedance and voltage of the output valves to this lower impedance. These transformers were commonly tapped to allow matching of the output to a multiple loudspeaker setup. For example, two 16 Ω loudspeakers in parallel will give an impedance of 8 Ω. Since the advent of solid-state transformerless outputs, these multiple-impedance outputs have become rare, and lower impedance loudspeakers more common. The most common nominal impedance for a single loudspeaker is now 8 Ω. Most solid-state amplifiers are designed to work with loudspeaker combinations of anything from 4 Ω to 8 Ω.[25

Set your expectation ...
也是Pioneer Elite用户。几个月前买来跟垃圾Pioneer HTIB比,看电影听歌样样好(那时候也全换上了Polk的5.1 HT音箱)。感觉天跟地一样。之后又买了后级功放(200w/ch,3 channels)推一对前置跟中置,音效又更好了。音压过足,很震撼!再来又乱七八糟加了外置解码DAC还有一些好线,音乐感又更好了。

搞到现在看电影跟听音乐彻底分开,又是一番天跟地。其实Pioneer Elite用来看HD电影还是很过瘾的,尤其是那些surround DSP,毕竟是analog stereo无法办到的。我就是用它来做surround processor。也是为什么我不想卖掉它的原因。

If it really makes you unhappy, get rid of it.

你级别没看清楚,这款不是Elite。先锋的噪音过高,就是用好的preamp改善一下,如果你把略好点的同级别的其他名牌,你会得出不同的结论。
VSX-1325-K就是Elite。是Pioneer Elite VSX-33。VSX-1325-K is model# specifically for sale in Futureshop only.

至少对这款功放来说,我认为是这样。在扬声器设置菜单里,我来回切换SW的yes-no (不接SW),听不出任何差别。
你试过Pure Direct了?在remote control有个auto surround button,按几下换去pure direct。pure direct 应该完全bypass DSP(包过LFE to subwoofer,EQ,等等)。

很奇怪,我把图像放大到400%,没看人任何Elite的标志。销售商巴不得把Elite的标签贴到上面,可惜的是,你说的特别制造相当于VSX-33,这是个很老的型号了,我记得以前处理掉的一款不是33就是38,令人失望,真的
Policy issue。Futureshop不可以买Elite。但是规格是完全一样的。

试过,没有区别。其实到现在我只是测试低音力度问题。DSP只会影响音质,还没有特别留意(也不必要了)。
结论是VSX-1325不够力推你的Klipsch floorstand往更好的音质(这个音质是你的expectation)。实话实说,我的Elite是要加上一台纯后级才来得爽。它们推的音箱也只是bookshelf size(2x 5.25 mid woofer for each front bookshelf)。当你说你用的是Klipsch floorstand 我就笑了。。。退掉VSX-1325吧。再往上玩就更花钱了。

110W @ 0.08%先不谈是不是一样型号了。
I don't disagree,虽然我不能很具体领会那个0.08%THD的效果。但是在一堆更好的器材比较下,耳朵很容易分得出什么是好什么是不好。

Back to the point, set your expectation。Nothing is perfect。

我当年就是从package开始,到5.1,到7.1,差点到了9.1,后来转向了双声道,真的走了不少弯路。
出发点跟你差不多一样。可能是读了很多你写在这里的经历,所以走少了弯路。

Agree!看来要加一台纯后级单推落地箱。这样只需要带pre输出的低档receiver就行了,毕竟看电影音质不是主要诉求。
买二手的就可以了。Receiver的amp section用来推surround setup,纯后级用来推主要音箱 - front and center。

sgyyz 给说说你听音乐用的一套系统(大约多少预算)和HT系统对听音乐的区别有多大, 音箱也是分开的吗? 不是现在很多DTS等多声道音乐录制, 如果用双声道系统会听不全?
预算得问你自己了。便宜有便宜的玩,贵也有贵的玩。HT系统还是可以听音乐,就是细节没那么丰富有力度。但这又跟你听什么音乐有关。有些人喜欢听electronic,trance,那种没什么细节又低频打心口的,估计HT+subwoofer也能胜任了。我自己>90%听vocal jazz。

音箱也分开。我想以后要换房子的话home theater跟music listening room一定要分开的(玩疯了)。

现在听音乐two channel都用英国牌子。就喜欢那种British sounding,有点厚音,高音不尖锐刺耳。现在的two channel setup:
Integrated Stereo Amp: Creek Evolution 2 (80w/ch @ 8 ohm)
Speaker: PMC TB2i bookshelf
Source: Arcam rDAC (using asychronous USB)

我几乎都不听DTS多声道音乐。我喜欢的音乐全都两声道的,没影响。要是多声道我就用HT来播。我也只用电脑做transport来播放digital files (flac,aiff,wav,apple lossless,ape,mp3)。我不用CD机。觉得没这个必要了。

我也买了这个receiver,那要不要退了呢?
如果退了,我买什么样的来推 Energy RC-70的音响?
你连箱子都还没开就想退啦?至少开箱接上玩一个星期要退才退嘛。又不用你付钱。可能你用会有惊喜呢?

因为您没有比较V部分。A只是AV中的一部分且往往是次要的部分。
AV receiver本来就是一个entertainment hub,或是AV distribution center。All-in-One,very nice!买来比音质然后失望有点跟自己过不去。我就很喜欢我的Elite。
