    Topping LA90 Review (Integrated Amplifier)

    Ah you mean, can I hear the ultra-low distortion at full power? Haha, agreed no. I am indeed talking about being able to get acceptable levels of distortion/noise as the signal goes far below the maximum output level. So, if there were amplifiers whose distortion/noise levels stayed at some...

    Topping LA90 Review (Integrated Amplifier)

    Raal SR1a with modded cables and connected to a transformer to get that kind of sensitivity. Headphone amps work great for driving things with high impedance, but mostly not so great for low impedance, and most would heat up internally a huge amount in those kind of conditions, if not get...

    Topping LA90 Review (Integrated Amplifier)

    I'm still puzzled on the "why do you care so much to judge" thing. You also don't know my application. Yes my example above is technically a headphone, but it was one that is meant for being driven on speaker amp taps given the low impedance. There might be cases where it might dip as low as...

    Topping LA90 Review (Integrated Amplifier)

    This is getting ridiculous. You really want to make the argument that going beyond what is necessary is equivalent to the fancy audio cable snake oil thing?? It really feels like you're making such an argument without actually considering the data. 2 things: 1) fancy audio cables don't even...

    Topping LA90 Review (Integrated Amplifier)

    While I would mostly agree, it is getting in the Zone of some headphone amps, and as someone who can hear the noise floor on some supposedly low distortion amps, pushing further into the zone of "no-way can we hear distortion or noise" has appeal. Well-made speaker driver units decrease the ...

    Topping LA90 Review (Integrated Amplifier)

    I'm not sure why you're spending all this effort dissing the Topping LA90, which is a confirmed achievement in low distortion measurements at anywhere near that level of power output at any price, much less sub-$1000 which is unheard of in the audiophile world. If you don't need or want this...

    Topping LA90 Review (Integrated Amplifier)

    True, but the profit vs. build cost margins were WAYYY higher "back in the day". From an inflation-adjusted point of view, the $500 - $1000 stereo from ~1970 would be like 10X that in current pricing. The $5000 - $10000 category of amps and stereos indeed have much more customer service/etc...

    Topping LA90 Review (Integrated Amplifier)

    Does anyone have a measurement of the idle power of one of the LA90 units yet? I did a search and couldn't seem to find any comments on the thread about it.

    Schittius vs. Topping 50 Stack - Amp Power vs. DAC Specs?

    I have both a Schiit Modius/Magnius and a Topping D30 Pro/A50s stack. My current summary on measurements and things I've used them for: Schiit Modius/Magnius: Strengths: POWER!!! It produces insane maximum power for a headphone amp, you can run it at high power and it doesn't seem to...

    RAAL-requisite SR1a Ribbon Headphone Review

    FYI to those on this forum. I got the TI-1a and modulo the question of how you do the OB compensation, in my current limited listening sessions, it sounds close enough to identical to the old amp/ribbon interface box that I couldn't really tell the difference except that it's of course much...

    RAAL-requisite SR1a Ribbon Headphone Review

    I ordered one of the new TI-1a adapter boxes yesterday after the announcement, and should have it in maybe 1 1/2 to 2 weeks from what they told me, and will report initial findings back to the forum. Personally, I like the idea of the OB compensation not being done in analog in the box. I'm...

    Center channel for Home Theater

    At various times in the past, with my living room AVR (Yamaha series AVR), I'd tried both L/R and L/C/R configurations, even tonally matched ones. For my own results, their "virtual center" mode has worked quite well, though admittedly with a loss of center localization when sitting far enough...

    topping a30/d30 pro stack vs a50s/d50s stack

    Your comments above presume that a balanced amp requires a balanced input. It depends entirely on the electrical implementation of the balanced amp, and the only ones that have the property of requiring balanced signals are ones that keep the separate legs of the signal and amplify them...

    Are headphone balanced cables snakeoil?

    Picking up this thread again to mention yet another effect related to the crosstalk issue and the superiority of using 4-wire "balanced" vs. 3-wire "unbalanced" headphone cables. Specifically, if you use a resistor-based "headphone volume attenuator" which is the standard way to do attenuation...

    Topping A50s Headphone Amplifier Review

    Hmm, I just rechecked the numbers, and I think I was limiting a bit on the maximum output of the A50s for the HE-6se and comparatively overshot for the A30 Pro. Shows what I get for going too fast estimating! Correcting the A50s formulas, it's ~2V + 6db = ~4V. Then, ~4V @ 64 ohm = ~250mW...
