Tekton Double Impacts

I don’t think a 50ft RCA cable is a good idea.

Very true. Also, even with an XLR cable it would be highly preferable to choose a cable having low capacitance per unit length (e.g., no more than around 25 or 30 pf per foot, and preferably less), and to drive the cable with a component having low output impedance (e.g., no more than two or three hundred ohms or so, and preferably less).

However, given the several fine suggestions that have been made of suitably priced amps that provide only RCA inputs, I would seriously consider using one of those amps in conjunction with a Jensen transformer that would accept an XLR input and provide an output that would be connected to the amp with a short length of RCA cable. That may very possibly even work better than an XLR to XLR connection, because there is a substantial body of anecdotal evidence indicating that the sonic quality of the XLR input circuits of many modestly priced amps is inferior to the sonic quality of their RCA inputs.

A suitable transformer would be the Jensen model PI2-XR if a stereo amp is being used, or a pair of PI-XR if monoblocks are being used. The PI2-XR is available here for $250. (That page shows a PI2-XX, having XLR connectors for both inputs and outputs, but you can specify RCA output connectors after clicking the "purchase" link). Further details can be found at the Jensen site.

Good luck. Regards,

I got the Impact Monitors in this weekend (in Farrari yellow), I'm very impressed. All the comments re: the Double Impact apply - airy, 3-D midrange & extended, clean highs, beautiful sound-staging, very dynamic with good bass response (paired with my Emotiva DSP10 subs). I listen primarily to Classical orchestral and solo piano.The 6 tweeter array seems to unravel orchestral textures better than a traditional cone midrange driver. The drivers are different than the top half of the DI's: 2 SB Acoustics
6 1/2"  mid/bass drivers and 7 Tymphany tweeters. These compare favorably with any Monitor I've heard-

@almarg Thanks for that information. Learned something new today. I will likely invest in that no matter which way I go with the amp. You are thinking it would be cleaner to input any amp RCA from the Jenson piece? And are you sure the transformer won't degrade the signal? I tend to lean toward a "less is better", minimalist view of a signal path. Don't throw anything in that isn't really needed because it's likely to degrade the signal. But if you feel this will allow a cleaner signal to reach the amp, and it will replace lesser circuitry in the amp, then it certainly makes sense and really isn't adding anything since it eliminates a circuit within the amp itself. This then puts the JOB amp back into play for me too. I wish JOB didn't have a Soup Nazi return policy to allow an in-home trial. That may actually push me to the Odyssey offering instead.

You are thinking it would be cleaner to input any amp RCA from the Jenson piece?

Not necessarily "any," but some and very possibly most, especially in the price range you are considering. Based, as I said, on anecdotal reports that have been provided here and elsewhere.

And are you sure the transformer won't degrade the signal?

I haven't used Jensen transformers myself, but a number of highly experienced members here who have **very** high quality systems have reported excellent results with them.

I tend to lean toward a "less is better", minimalist view of a signal path.

Likewise in my case. But there are exceptions to every rule, and I suspect this is one of them.  And as you alluded to, the transformer may be simply taking the place of a low quality op amp device that is used in many designs to interface between a balanced input and an unbalanced internal signal path.

@333jeffrey - Thanks for the response. I'm a "HUGE" live music fan and my goal is to have that kind of reproduction in-home. Looks like I better give Eric a call and see what I can find out about this Mini-Ulf!
