    Forte II with single ended or push pull integrated tube amps ?

    in 2-Channel Home Audio

    Posted

    hi,

    I have a pair of Forte I's paired with a Cary SLI-80 kt-88 pp

    amp. It's a very satisfying combination, particularly in the

    triode mode. The system can seduce you with its warmth and charm,

    or overwhelm you with its power and dynamics, take your pick, it

    can do both.

    I have a pair of Wright Mono 3.5s paired with 1979 Cornwalls . I have

    never used them with the Fortes, but I would guess the sound

    would be much alike. The SETs are much different.

    Less bass impact for sure. More midrange and treble transparency for

    sure. A more delicate sound and in some ways with some types of

    music, more lifelike.

    Is this accurate re: high efficiency speakers

    Hi,

    from a thread on Audiogon

    "01-19-06: Audiokinesis

    I agree

    with the posts pointing out that a high efficiency system usually has

    better dynamic contrast than a low efficiency system.

    Let me try to explain why. It's a nasty little secret almost nobody talks about.

    Theoretically,

    a loudspeaker's output will increase by 3 dB for a doubling of input

    power. In practice, this is ALMOST NEVER true. The reason is power

    compression (also often called thermal compression), and its primary

    cause is voice coil heating. As you increase the power going into a

    voice coil, it heats up. As it heats up, its resistance increases. As

    its resistance increases, more of the power going into it goes into

    overcoming that resistance (heating it up still more) and less goes

    into actually producing sound.

    Let me give a few numbers as an

    example (drawing on measurements posted by Bill Roberts on Audio

    Asylum). At normal volume levels, the typical 86 dB efficient speaker

    may well only give you an average of 2.5 dB increase in loudness for a

    doubling of input power. So let's say you have an 86 dB efficient

    speaker playing at 80 dB average volume level, and along comes a +20 dB

    peak (quite common). This speaker will compress the peak and you'll

    only get about +17 dB. On the other hand, a high-efficiency system (say

    96 dB efficient or higher) usually has negligible power compression at

    normal listening levels, and will more than likely give you the full

    +20 dB that the peak calls for.

    Once again, this is a

    generalization - I'm sure there are exceptions, but unfortunately this

    is something nobody measures and includes in their specifications.

    Differences

    in the power compression characteristics of the various drivers within

    a speaker often cause the tonal balance to change with volume level,

    with woofers typically suffering from more power compression than

    tweeters and therefor many multiway systems sound dull at low volume

    levels and bright at high volume levels as they've been optimized to

    sound right at medium to medium-high volume levels.

    On another

    note, bass reflex loading only increases efficiency in the region of

    the port tuning. It does nothing for midband efficiency. The reason why

    bass reflex speakers are usually more efficient than sealed box

    speakers is that the driver parameters most suitable for reflex loading

    include a more powerful magnet system, which is what raises the midband

    efficiency.

    Hope this helps some.

    What volume?

    in 2-Channel Home Audio

    Posted

    hi,

    with my Wright Mono 3.5s and the Cornwall Is listening mostly to jazz measured 10 feet from the speakers

    with a Radio Shack digital meter max levels fast recording

    late night soft 65 db

    late night loud 70 to 72 db

    daytime soft 70 to 75 db

    daytime loud 80 to 85 db

    so most of the time the Wrights are well within their parameters

    rocking real loud at a party with the Forte Is and Cary SLI-80 - rock not jazz and not often 95 to 105 db

    good listening

    At last, we agree! Hook 'em, baby!

    Half-time. UT 16; USC 10.

    But

    that dough's going to insurance companies, who have employees, who earn

    pay-checks, who buy things from the companies who pay premiums - and

    they have shareholders, who receive, who buy things from

    companies who pay premiums.

    If the economy started out with

    $1MM, and you shuffled all the money around into premiums, attorneys -

    whatever example you want - in the end, the same $1MM is in the

    economy.

    Yes but 2.4 % is nonproductive, it's going around in circles supporting the tort system, not the economy.

    It's late here in PA. I'm going to watch the game and go to bed. You can have the last word.

    A good debate. Thanks for being civil.

    good listening

    I don't think it's incorrect reasoning. For example.

    We all pay for liability insurance, auto, homeowners, and if we own a

    business or are a professional for corporate insurance or professional

    malpractice insurance. The higher premiums means less disposable income

    to spend on goods or services and less money to stimulate the economy.

    In the case of a small business less money to distribute to the

    employees as income or benefits or less employees.

    The rising insurance rates corporations are experiencing are passed on

    to consumers in the form of higher prices. Goods and services

    cost more, demand is decreased when prices are high and therefore less

    goods and services are produced. Corporations don't grow as fast

    and less jobs are produced. Corporations become less competitive

    compared to foreign corporations, which don't incur these nonproductive

    costs, and thus sell less on the world markets .... less growth

    & fewer jobs.

    Insurance does not cover all of corporate liability and reserves are set

    aside to cover the cost. Less money therefore for R&D and product

    innovation and less growth. Less money for dividend distributions

    to shareholders. Less money to stimulate the economy.

    A corporation which experiences a large class action settlement or

    threat of one ( take the drug company Merk as an example )

    usually experiences a decline in stock values. 50% of Americans

    own stocks. Again a loss of income and less disposable income to

    stimulate the economy.

    Lower stock prices for a company means the company has a diminished

    ability to raise capital for growth or R&D. Less corporate

    growth and fewer jobs.

    BTW Texas is ahead 16 to 7. I'm with you on this one.

    "Golly! You mean 2.4% of our GDP is just sucked right out of the economy"

    The short answer to that is yes. Everyone pays the price. For the

    economy it's a negative feedback system. It doesn't matter if

    it's me or some who won a judgement against me who has and spends

    the money. The dollars are fed into the economy and the economy is

    paying a 2.4% premimum to run.

    The price paid is 1000 dollars a person. An average family of 4 with an

    average income of 68000 dollars with 75% (51000 dollars) of that

    as disposable after all taxes are paid pays $ 4000 more for the same

    good and services then if the tort system was nonexistant.

    That's 8% of their disposable income.

    That's too much,

    Tort lawyers don't create wealth, they just redistribute it. I

    becomes

    a cost to the rest of us that pay for it by paying higher prices

    for goods and services as the cost of litigation is passed

    on.

    The amount of wealth that seems in our country compared to the rest of

    the world, excessive. The cost of torts is project to

    be 2.4 percent of our GDP in 2005. That's more then

    1000 per person per year.

    The injured in our society deserve to be compensated. It's up to all of

    us through our legislative system to determine if we as a society want

    to continue to keep paying at this level. I for one think the

    cost is too high.
