-Would you prefer the Sonicap, Mundorf Supreme or Dynamicap as the tweeter cap and why?
"I" probably would have used the Sonicap or Mundorf Supreme S/O. But, I am not you. I do not have your equipment, nor was I considering Dynamicaps to start with. As I have previously stated. The cap on the high-pass of your speakers is known to be grainy, gritty, bright, and forward. When you say "lusher top end", I picture you merely running from the factory cap. Maggies are not bright/forward on top by nature. When moving away from the factory cap, "I" do not feel a quantum shift is in order. Hence, the Sonicap. This was reinforced by one of my customers that tried many caps in that position (including the Dynamicap). My belief is that many of the folks that have used warmer caps (Obbligatos to Dynamicaps) would appreciate a bit more sparkle even though they appreciate the shift away from bright/forward/brash.
As for the Dynamicap, I'm sure you can find it. I always found it's flavor to be a useful tool in certain applications. I never liked the build quality, or the QC. So, dropping them when the price doubled was an easy decision. If you do buy a pair of 10uF, pay for the epoxy version ($2 each). Also request 1% matching of value and ESR. I found both to fluctuate wildly.
-What have your 1.7 upgraders said after their upgrade project was completed about the sound enhancement?
Most were not specific in their desired improvement, and they were equally nonspecific in their acknowledgement of their newfound performance. Those that were more specific leaned towards better bass, more dynamics, and more refined highs. But, not all. One customer removed the 12ga coil because he felt it made the 1.7s bass heavy. He went back to the factory coil. He was the only one to do this. He tried several caps in the high-pass including the Mundorf Supreme S/O, but found he liked the Sonicap better. The 1.7 is a mixed bag, unlike say the 1.6.
I too would now agree with rollo, 'the speaker is the speaker'
I'm not included here. As stated before, this statement to me is more of "the exception rather than the rule". I only touched upon his statement because it is somewhat applicable to the "1.7" IMO. And of course, I spelled out why in my previous post.
After this project I also may consider coupling capacitor changes to my Classe CA-200 power amp and/or speaker cables (using IXOS currently) as well but one step at a time
I generally go to the XO first, but perhaps not here. Based on the speakers in question along with your desired results and associated equipment... Their is a strong argument for analyzing your cables, and coupling caps (upstream from your amp). You do not want to swing too far in one position. You may find yourself tuning differently once other issues have been addressed. Are you using balanced out of the pre, or single ended? Balanced from your oppo? Which 6922s are you using, and why? What percentage of the time are you using each source? Which sounds best? I did not think your pre had a phono stage, so what are you using for a phono amp? Which model IXOS speaker cable, and what length?
Not sure how to make this 'custom Alpha Core 1.4 coil order on the Sonic Craft site so I have included my e-mail address below for pricing and payment.
Four years ago, we went 100% ecommerce. So, you will need to create an account on our website. You can add items to your cart. Once you start into check out, you will be given shipping options.
