Listening to it right now as I tweak a crossover for a JBL k2 clone.

OK, this is 100% IMO, no support, no measurements.

From the very first day I started playing with single-driver speakers, I'm heard that EQ of any sort "sucks the life out of the speaker". Well, most wide-range drivers have a rising response, and a rising response gives the impression of "life" and "detail. Slapping a BSC filter on a hot speaker brings the response more or less into balance, and means the rising response is ameliorated. The speaker becomes less hot, and the "life" and "detail" become muted.

I don't have any problem with anyone who likes a hot speaker. Your ears, your hobby. But I strongly believe that this issue is one of balancing the FR or not. I can't listen to a hot speaker. Most will set off my tinnitus. I like a reasonably balanced speaker. YMMV, yada, yada.

OK, there's my testimony.

Bob

DSP vs no DSP ?
I've first hand experience of this with the Fostex FE127e, too hot out of the box, and BSC 'sucked the life out of it' - I moved on, to other drivers.

But I'm still interested in first hand experience of the DSP-in and DSP-out test. I'm quite surprised (almost) nobody has tried it !

I'm not sure what any of this has to do with the miniDSP products at this point. A DSP in/out test is something you probably experience every day. Probably most of the CD's you listen to or audio you stream, or whatever, has been DSP-processed at some point in time.

You're asking for subjective opinions, but I suspect you're looking for the answer you want to hear before arriving at your conclusion. The only person that can answer your query is you.

No, I only read that one sentence of your reply and completely ignored all the rest.

I've been using a 2x4 minidsp together with nanodigi for several years. I've never used analog inputs so I can't comment on that. But I can tell you that replacing the on board digital volume pot with an analog pot (alps) was a huge improvement in terms of SQ.
I am satisfied with the onboard dac.

LXmini SL's new speakers are based on minidsp 2x4 using analog input, so I guess ADC is not a major issue for him.

Yes indeed, my question is not about 'any DSP' nor is it a search for negative or positive opinions on the use of DSP. I want to know about the minidsp and it's use between source and power amplifier. My reason is twofold - a)I've been thinking about making an analogue pre-amp with tone controls but this is such an old fahsioned approach I thought a DSP approach might be more flexible, b) my single full range driver is not 'flat' in my room and some EQ would be welcome

I'd like to hear that the darn thing is transparent and is therefore, a real bargain that can be used without thinking twice about it. But it will take $ and time and effort for me to evaluate it although as you rightly point out this is the proper way. However, I can only evaluate it in my current system and it may not be very typical (it's mono for starters). So asking for opinions from others provides me with additional information to consider.

There's always a danger that people who buy it will defend their purchase by telling me it sounds good even if it doesn't. That's why I value opinions from people like Bob, who I know to be objective.

The best explanation that I can come up with is compression. It seems to kill some of the dynamics of the music. It is only opinion. No facts. I still use it to prototype speakers as it helps me dial in crossover possibilities. I am just a rookie.
