    Heschl Hal 350 Integrated Amp

    I'd be more than willing to run one in for a few hundred hours. You know, if anyone happened to have a unit that needed running in.
  2. Yes, indeed I do. Yes, I realize it is meant to represent a sharp s, but for the sake of using a word that is easily typed I've been using "GroB".
  3. Is it unroll-able? Or can it be read in its rolled form by anything other than the software that created it?
  4. I thought I'd try the 907NRA through the ML2 Ltds with decoding by Clay's GroB DAC. The top end, mids and vocals are the best I have heard yet. Bass is incredibly tight and focused but could use a little more punch (which was unexpected). As Christmas presents to myself go, it's the best I've given me so far.
  5. I love the idea behind them. Is there anything anywhere that tells you what the little circular acoustic map that they generate actually means?
  6. Ooooh, you take that back. We have yet to have that GTG to cure you of this completely unreasonable love of tubes that you have developed.☢️
  7. One gorgeous Sansui Alpha 707MR. http://yahoo.aleado.com/lot?auctionID=w280940197 Currently cheap but with a long way to go.

    Bottoms out at 6.8 Ohms I believe, very amp friendly.

    They sound just fine on valves for the slower stuff, if you want serious dynamics though then you will need serious current to feed them.
  10. I finished with the Rotel over a week ago but I just haven't been interested in doing much typing lately so it's taken me this long to get to the write up. Work has gone and got me cranky so that didn't help much either. Anyway, here it is, one Rotel RA-1412 write up. Cue the copy and paste noise. It is with considerable mixed feelings that I type this review of the Rotel RA-1412. As readers work their way through this review I would like them to keep in mind that while I will say some things that sound “bad” that does not mean that I dislike the amp in question. I do like it, quite a lot in fact, but that does not change the fact that I hear what I hear. I will also likely make some comparisons and assumptions, those are mine and are based solely on my opinions, obviously yours may differ. I make mention a few times to a “lack of fidelity” which I take to mean a lack of detail/micro-detail/high enough resolution to keep everything together. I’m not exactly sure what causes this, it could be the fact that the RA-1412 was designed prior to the existence of digital media and this resolution was considered sufficient for vinyl and cassette tapes or it could be that some of the capacitors or resistors within it have values that have wandered just enough to cause such an effect in its 42 years of life on this blue/green audiophilic globe of ours. As per usual I was using my YBA Heritage cd100 as a source (DAC duties were partially outsourced to my new GroB DAC but mostly for the purpose of running in). Cables were Aurealis Dragon interconnects and generic 14 AWG stranded speaker wire (which was the thickest wire I could force through the speaker posts). Speakers were my trusty Lenehan S2R stand mounts. Gain. The Rotel has a truckload of it. So much that I made the decision to move ahead with the minus 10db toggle “on” so I had some measure of reasonable control over the volume. Without the muting on the difference between too quiet and too loud was just too small to be practical. OK, on to the sound. Highs: Lovely tonality but a lack of overall detail can mess things up a bit in orchestral listening, also hard rock listening, probably any music that has many instruments playing at once. Never hard or bright but a touch unfocussed on triangle. Brass is a joy to listen to, not hard or bright but very, very “brassy”. If you don’t look for the minutiae then it sounds very nice. Enjoyment score would be an 8.25, detail score would be a 7.0. Mids: Just a bit on the bright side and sometimes a touch hard, sounds great on slower styles but loses significant focus on fast music with multiple instruments active at once. Acoustic strings have a nice addictive air to them. Really nice in the mids, almost reminds me of a slightly unfocussed version of the Rega Elex-R actually. I’ll give it an 8.0 but that can drop as low as a 7.0 on more convoluted tracks. Bass: Full, large and satisfying. Yes, a large and dynamic bottom end but not overpowering. Not so punchy, more a great big rolling and clashing creature that stays in its soundstage cage. It can’t get out so it can’t punch you in the chest. 8.25 Vocals: Loses some focus with hard sung vocals (both Male and Female) but with softer vocals it can really impress. Slow 7.75, hard, 6.5. Soundstage: Big, wide and deep, it feels natural even though it is a bit broad and loose in the placement of instruments within it. Size and entertainment score 8.0, details score 6.75. Overall Performance. Large, full and lightly warm in the bass, carries a big presence that is dynamic and musical in the macro if not so great at the micro. Ability to Emote: 8.25 on orchestral music, slower styles and faster styles where there is rarely more than one instrument playing at once. 7.0 if you’re chasing detail in audiophile recorded tracks. Electric Guitar Test: 8.25, all good here. Even with two guitars going hell for leather there is no problem at all. 80’s Rock Test: 8.25 No lack of focus or detail here, but then that isn’t really the point of most of the rock that came out of the 80s. Overall a very enjoyable amp, but noticeably a product of its time. Since it isn’t an amp with a warm mid range then that lack of detail is readily noticeable. However if you needed an amp for some big speakers in a garage or shed sized area then this would do you proud. Particularly if the speakers were of a similar vintage.
  11. What does it mean for an amps dynamic capabilities if it barely increases wattage with a halving of the speaker impedance? Assuming the speaker in question is a fairly typical one that does drop its impedance as frequency decreases (ie bass frequencies have a lower impedance than treble).
  12. Congratulations Sir Sanders, you win no prize. And, not a typo as such. For a reason I do not understand, most Japanese companies list an amps "Damping Factor" as "Dumping Factor". That's how you know it's Japanese.
  13. And remember there are no prizes for guessing.
  14. I've never used it but if you enter in the total weight of the item it looks to be a total cost estimator. It just adds on postage within Japan to the current auction asking price.and then externally to wherever. I would trust it about as much as ebay's standard postage numbers (which is to say, not very far).
  15. They don't elaborate Blake, those figures are all I've got. I think they are bragging with the two frequency specs, this is how flat it is from 20Hz to 20kHz and the full range within the standard + or -3db range is 2Hz to 180kHz.
