I have become strong believer in Class D amps [owned Audio Research, Moon, Ayre top models] If you want lot of power, transparency - go for something based on NC1200 or 1ET7040 modules. Buckeye has quite good reputation in uS. If you want something good looking - go for Apollon Audio from Slovenia

I would suspect gain matching between source/avpreamp and amp. Marantzes are going their own way in terms of Engineering [low volts on pre-amp forcing higher gains on power amps, which exacerberates hiss from tweeter] . All I can say Purifi at 20dB gain is silent on Focus.

Hi, it is bit more complex [like everything with Trinnov] and you have basically 3 options, how to get digital out 1) red marking - use DB25 digisnake and have up to 16 digital channels [people use it mostly for active speakers with digital in], this can be set-up in Sources menu. This...

Phone will be pain. Ipad is on the edge, if you want to do anything like target curve, unless you are diamonds cutter or watchmaker.

yes, there has been quite some discontent about this moemtization model. You can find sale for 149 periodically. I have used this windows app on Denon X8500 and it brings everything to whole new level - allowing you to fine tune your sytem. LOT of new options, REW data imports, etc It makes...

You will need to recalibrate. Offers improved control over settings, I think is a no-brainer. Most importantly you will see what Audyssey is trying to do and probably you will find some weird things. You can also experiment with limiting corrections, removing BBC dip etc ...

acoustic treatments should ideally be a solution to a specific problem. Will this IKEA thing do, what it advertises? Probably yes. will it make your system sound better? Maybe yes, maybe not.

Blue trace is speaker measurement - so teoretical capability in room for speaker, measured by sweep. Black trace is real time analyzer of one relatively complex music - complete orchestra, averaged over 1 min. There is virtually nothing above 15kHz,and quite not a lot happening above 8kHz [which...

The same is valid for every cable - I have similar experience with signal XLR cables - StarQuad with higher capacitance vs "normal" XLR cable. Higher Capacitance = less treble.

Interesting - I thought dip between 300-500Hz and 1-2kHz is my acoustics/placement, but I can see similar pattern in your measurements. Now, it looks like this is actually typical in-room response.

I can serve with Class D Amp measurements - violet ones, down there 25A, 225W/400W/425W at 8/4/2Ohm respectively. Graphs are offset by 10dB. Measured at 80dB 2.5m distance.

Something normal - heavier sort, with blackout back. I think from IKEA.

BF’s are great for sure, for their intended use, and one of the few good looking subs I am now going into Double Bass Array setup with 8 subs. Simulated in room 12Hz at 122 dB https://en.wikipedia.org/wiki/Double_bass_array and there I can not use sub with 2 opposing woofers.

It is trapezoidal shape with the lenght of slighltly more then 6m and front wall is longer with 5.5m. so around 32sqm and 3m ceiling height.

Those suggesting to go for Small and 80Hz were right.

re D Class - there are 2 models / modules with higher current Purifi 1et7040 that offers 40A vs 25A of standard Purifi in EU it would be e.g. Apollon Audip or boXem Audio in US people talk highly about Buckeye...

I am really excited about the general state of play for MCH and HT. After really bad years with format wars, obsolete HW etc. We live the best times - lot of immersive audio content, 4K, streaming, more or less affordable processors that are good. D Class amps with tons of power running cool...

And as a consequence -> I am starting to re-build my subwoofer section. Even me being very loyal ML Customer - I need to say, that, unfortunately, ML has its ceiling, if we talk about really serious, high SPL, low FR extension installation. BF subs do not make the cut, as they are [among other...

Some news - I have pulled the trigger and gone full speed to extend my Altitude to 32CH Primary reason being this -> https://www.trinnov.com/en/blog/posts/trinnov-reveals-revolutionary-waveforming-sup-tm-sup-technology/ this will require approx. 8 subs to work optimally, so want to be...
