Aleph 5 + Dunlavy 4

Thanks again !
I did see Drubin's comment on impedance match !
I got a ratio of 46 = 23k/0.5k, how is it ? Maybe this number accounts for a little bit bass shy. AI L-1 or Aleph P of my once candidate won't improve this ratio. I did do something on the primary points of my back and side walls, the reflection is kinda under the controll and no toe-in is applied.

About my source, do you mean cd-63 or cd-63 plus AA gears ?
Do you think a Perpetual p3a replaceing DDE with some upsampling trick will help ?

Hi Felix, I did try following the manual and the essential points (wide separation and distance) but the long wall setup and toe-in. Long wall setup is not the option for my listening room arrangement. In my past experience, I do not like the sound when PSB is toed in. What is the theorectical benefit of toe-in ? image and directional treble ? not bass I guess. Thanks !

Thanks for the responses !

Drubin, I guess what I want to know is if A/D combo is what it should be or a little bit bass-shy, especially both KSA and PSB are known for their bass performance or too exagerated. In fact I'm not sure if I need more power. Right now my preamp points to 10-11 o'clock position in pretty loud listening leve while the previous Aleph owner pointed to 3 o'clock driving Maggies 3.6.

Sean, yes it is big change (and improvement). In fact, I like them very much. I just want to know if the bass of my previous system is too exagerated (or slow and muddy) or the current one is just right (quick and tight). Thanks for your opinion !

My cable is Audioquest midnight-2 driving by ARC LS-3B, AA DTI-PRO32, DDE V3.0 and Maratz CD-63. The roomm is about 16Wx24Lx17H. The speakers are along the short wall (not as suggested, I know) but 10.5' apart. 2.5' from the side wall, 7' form the back wall without toe-in. There is no front wall since it faces a open dinette/kitchen (15'wx22'L). The listening position iss about 11' from the center of the speakes. Is it good or any improvemnt can be made except "along the longwall" ? Thanks !

Viggen,

you thought sounds like "you know what you are talking about" to me. Did you imply something like Z6 or Z8 ? I know low resistanve is better, how about capacitance and inductance ? Which direction is better ? I found www.audionet.de/pdf/english/highendnews_amp1.pdf. The reviewer switched from midnight to Z6 and gained significant improvement. What do you think ? Thanks !

I just took off the grille and checked. I think, for mids, the felt is designed to limit both vertical and horizontal dispersion equally and for tweeter, the felt limits a little bit more vertical dispersion than horizotal dispersion. I guess that this patented design explained why the first direction is still kinda under control in my setup (2.5' from side wall and not toe-in). Last night I tried the toe-in. Just like my past experince, I can not experience any expected improvemnt. When I toed in PSB, I can experinece much stronger treble energy and a little bit better image but not SC-4. Maybe I should try it again ! I did find one thing, my old listening spot seems to be in the null of bass band. If I moved 0.5' forward or 1' backward, the bass is mucg stronger. BTW, as mentined, I do not have back wall to my seat so I wonder if it is from the standing wave caused by the reflection from the front wall or the kitchen. very interesting !
