amplfier

Hello, This is my first post here and I am a newbie in audio science, so I would like to apologize in advance if I use any incorrect expressions or phrasing. My very old audio system recently broke down, but the 4-Ohm passive speakers are still functioning well, and I'd like to keep them for...

Hi all, quick question. I’m looking at two amps from Apollon. The Purifi 1ET7040SA DM Luc Dual Mono Amplifier and the Hypex NCx500 DM Lux Dual Mono Amplifier. The Purifi is power rating is 250/500/950 watts at 8/4/2 ohms. The Hypex power rating is 380/700/700 watts at 8/4/2 ohms. Do people...

I would like to begin with my setting: I am connecting a Topping E70 (ESS 9028 Pro, possibly that chip operates at 1 watt with highest sample rate?) to two KH80 monitor speakers (200W maximum power for each, 114dB). Sampling 32 bit and 96kHz. However, I am listening at only 0.95m, and I control...

This is NOT a review, but an overview of the Aoshida A6 amplifier DISCLAIMER I know that many on ASR completely denigrate tube products, especially the very cheap ones with more aesthetic than functional purposes, as in this case, but considering the probable intended use of an amplifier in...

Hi folks, need some help with upgrading my current amplifier to something more advanced. Currently I have Monolith Liquid Spark connected to the dac section of Fiio K3 (second release). My HP are Fostex T60rp and LS drives them pretty well even on default gain. But I think (or it seems to me)...

Amir measured a dead spot at the cross over frequency right above the tweeter axis. This is readily apparent when playing a ~1.5 kHz tone and results in a musical reproduction that lacks presence: subjectively sound comes from around the speaker, not coherently from within the speaker...
