    New Matrix M-Stage?

    Bait and switch?  Looking at the Hlly website and his eBay store is interesting - they have those Little Dot amps, but then Hlly-branded amps that look identical.  In the case of the Matrix, that would make it a clone of a clone (I'm speculating, of course, since as of now they only have the...

    Phono Preamp

    First off - I haven't used any of those, so I can't speak to them specifically.  However, when considering a vinyl playback system and specifically a phono preamp, the cartridge being used is very important - probably more important than the turntable itself, because it is the signal from the...

    Most neutral, accurate headphone amp/preamp in the 300-500 range?

    I have the M-Stage.  Neutral?  Accurate?  Yeah, I'd say so.  Since amps don't actually do anything on their own, their performance has to be taken in the context of a system - in my system the M-Stage let's the HD580s and DT880s sound like I expect them to - strengths and weaknesses.  I think...

    Appreciation of the sound from speakers vs. headphones

    I've had a variety of good stereo equipment over the years, and I've always preferred speakers to headphones if I could listen to either.  My first good stereo had a Superphon Revelation + pre, B&K EX442 amp, AR ES-1 turntable, Nak BX300 tapedeck, JSE Model 1 speakers (JSE used the same infinite...

    B stock Sennheiser 600 and 650

    I bought B-stock HD 580's way back in 2000.  As delivered, the headphones had a cutout in the left speaker.  It was caused by the cable not having a good connection.  I pulled the cables, carefully cleaned everything and reinstalled - no more problem.  I still have the phones and they still...

    Digital Music Storage and Playback Options

    Olive makes a couple of interesting products that can be used together or independently.  The main server (complete with CD burner and large HD) is on the pricey side at over $1,500, though.  Haven't heard them, so no idea how good they sound.  http://www.olive.us/home.html   JB

    Matrix M-Stage amp review: simple, cheap, and excellent.

    The pre-amp outs do not mute when a headphone is plugged in.   JB

    Discrete PHONO PreAmps vs integrated PHONO PreAmps in Audio Receivers

    Think about going used!  For a preamp, I wouldn't hesitate to pick up a classic design from the early 90's or even 80's - there's just not much that goes wrong over time with these things.  For example, there's a Threshold Fet9 over on Audiogon right now for well under $1k that is probably at...

    NAD C 375BEE Integrated Amplifier Does anybody had heard it?

    LOL - you are kidding about the efficiency of a Class A amp, right?  Class A's biggest inefficiencies are at low levels, where the output devices are biased with at least enough juice to develop half rated power - and if it's not developing half power at the speaker terminals, then any extra...

    Discrete PHONO PreAmps vs integrated PHONO PreAmps in Audio Receivers

    A couple of less obvious points in addition to the two already mentioned:   -  a receiver is built to a price point;  any phono stage is likely to be an afterthought much like the headphone jack.  Having said that, I was surprised by how good the phono stage of a budget Marantz integrated...

    NAD C 375BEE Integrated Amplifier Does anybody had heard it?

    Quote: Like I said, I had that Marantz in my system for a month.  I know they claimed it could be switched to run class A up to 25 watts but I never believed that.  The heat sinking just didn't seem to be there to dissipate that much heat, and it didn't run hot enough (My 50wpc Threshold...

    Matrix M-Stage amp review: simple, cheap, and excellent.

    I recently bought one of these when my living situation changed (divorce, moving to an older apartment building with thin walls, etc.).  As a result, I have been selling off all my old stereo stuff (and it was some pretty nice stuff).  Turntable, integrated amp and speakers are all gone, along...

    NAD C 375BEE Integrated Amplifier Does anybody had heard it?

    I really doubt you're going to find a truly class A amp, integrated or not, in the price range you seem to be looking in.  The closest I can think of are the low powered Monarchy Audio amps, but I have no idea if those are still in production or what Monarchy might be charging these days.  The...

    List of amps that double as stereo amps

    Portal Audio Panache - what I'm using. If you're into the single ended tube sound, may not be your cup of tea. Powerful, with reserves that I don't think I've tapped into yet. Captures much of the midrange magic of my old LFD Mistral integrated (another SS integrated), but with better bass and...

    bada ph-12 "hum" - help!

    Grounding issues can be caused by connecting equipment via analog connections - what do you have hooked up to your system? Have you tried disconnecting one piece at a time? I was able to resolve my hum problems by not connecting my TV to my stereo. JB edit: this article is very helpful in...
