Help - amplifier matching problems


I own a pair of Aerial 7Bs and am using a BAT VK-30 as a pre-amp, a Theta Miles CD player and a Classe CA-100 amp (100wpc into 8). I love the sound except for the bass, which is a bit fat and not taught enough. Thinking that I needed more power, I purchased a Krell KAV-250a (250wps into 8). After letting the Krell burn in for 100 hours, I did a side by side. The results, I miss the Classe midrange. The Krell clearly controls the bass, does not have that "tube" coloration and is much more powerful. However, it sounds cold and I believe the soundstage dramatically disappears. Can anyone suggest a good match, or should I keep the Classe and get more efficient speakers? Thanks in advance.

Why don't you bi-amp using the Krell for bass and the Classe for the midrange and tweeter?? I would think that would provide great bass and sweet midrange/treble performance.
Jtinn, it has been brought to the attention of more than a few folks that you have a tendency to post & recommend brand names of products that you sell in your store. We've also noticed that YOU have never mentioned that you are indeed an "audio professional". As such, we think that most audiophiles and consumers would consider this offensive and self serving. The fact that you've used the Audiogon discussion forums as an advertising campaign without making your affiliations clear says more about your ethics ( or lack of them ) than we ever could.

The fact that you've been a "cheerleader" for a few other brands that you carry on a somewhat regular basis can only help you and your store. We state this in terms of increasing public awareness of those products and the increased demand for them due to brand name recognition and the amount of recommendations that they get. The funny thing is that you yourself are doing the recommendations, putting those product names in the limelight and creating the increased demand for them. We can see how one would find this type of "free advertising" quite convenient even it it lacked both tact and ethics.

Potential customers and forum readers should be made aware that Jtinn is indeed involved in selling / marketing / representing specific products and as such, might be construed as biased towards these products. At the same time, Jtinn might also tend to steer folks from another make / model that he doesn't sell in his stores. While many view his input as being "fair" yet "unbiased", you need to better understand where he is coming from. That is, you might have thought that they were "fair" until you knew about his "bias" and affiliations. That could put a whole different slant on how his recommendations are / were received.

We consider it a shame that someone that could have been considered a very friendly and helpful dealer might now be considered a "manipulative rat" with something to hide. Rather than be up-front about one's affiliations to begin with, they might now come across as someone that was trying to manipulate the market to their advantage. Too bad they didn't do the right thing to begin with as all of this would have been avoided. Sean

PS... You and your partner were given fair warning in the thread regarding "ethics" and business professionals.
Sell the Krell and get another Classe CA-100 and bi-amp the speakers. With the rest of the money get a good set of speaker cables, Harmonic Tech maybe. I promise you will thank me.
I think Sean has a legitimate point, but makes too much of it. Commercial affiliations should be disclosed, but it is also true that every one of us has biases and makes recommendations based on what we prefer. I assume that one of the primary reasons that jtinn sells BAT (assuming that in fact he (she?) does) is because he prefers it to other brands that he might sell. We all do the same thing with respect to the equipment we prefer to buy or recommend.

But to the point: Aeriels need lots of current. I like the biamping with another CA 100; that offers good value. I also think that a much bigger Classe might be a solution. I drive 10T's with SimAudio (damping factor >800) and the Aeriels are very taught and punchy. Frankly, I also like the BAT idea, especially as I have a vague recollection of JA expressing some concern about impedence matching with BAT, but I think that was in connection with one of the tube amps. Sorry for the vague reference, but worth a bit of checking.
If you still have both amps,I would second the bi-amp trick,I also agree with Sean,good luck,Bob
